How Dishwashers Work?

A dishwasher is a household appliance that washes dishes in some or all of the following steps: pre-rinse, wash, rinse and dry. Dishwashers are typically made of stainless steel with white plastic handles and controls. Your dishwasher may have an electronic display panel to set cycles and options. It’s important to know how your particular dishwasher works so you can care for it properly! Basically, the machine follow these steps:

1. Adding water: Cold water is pumped into the machine.

2. Heating the water: The heating element at the bottom of the machine heats the water to meet setting temperature.

3. Adding detergent: Machine automatically opens the detergent dispenser at the right time.

4. Washing the dishes: Shoots the hot water through jets to get the dishes clean.

5. Draining the dirty water.

6. Rinsing the dishes: Sprays more clean/ heated water on the dishes to rinse them.

7. Draining again.

8. Heating the air to dry the dishes off (if the machine has this function and user has selected that setting).

How Dishwashers Work

In this blog post we’ll show you how a typical dishwasher works by highlighting the various parts that make up your machine, as well as what each part does during the cycle. We’ll also discuss any common problems people might experience with their dishwashers!

What is the structure of Dishwasher?

A dishwasher is an appliance for cleaning dirty dishes in your home. After you wash with water and a bit soap anywhere, it will be stinky because food residue was still remain on dish until we cleaned them with dishwasher . So people invented good machine that have good performance for cleaning. It looks like similar as washing machine’s plumbing part but there are many differences between them.

Its size much smaller than washing machine . Also water temperature difference is big inside these two machines too; where as washing machine use water around 60 degree Celsius and dishwasher can use high temperature water around 80-120 degree Celsius.

First of all: there are three basic parts of the dishwashers operation: plumbing (water supply), electrical (power input) and controls (programming). How these three systems interact determines whether your dishes come out clean or not.

The water is turned into steam by the heating element, goes up through the spray arm and comes back down to be drained out. In between, a material called “soap” is added. Soaps are chemicals that you can buy at the store. there are lots of different kinds and they all work differently (another story). When soap gets wet it breaks up into many smaller pieces — this is called “dissolving”.

Since dishwasher detergents help clean your dishes by making it easier for water to break up grease, food particles & stuff, it’s very important that you use enough detergent or else your dishes won’t get clean. if you don’t put enough in the machine before starting (or even better: add more during the wash cycle), your dishes will come out dirty.

The water (and soap) drain down into the bottom of the dishwasher tub and then back into the plumbing through a trap & drain hose. a “trap” is just two pieces of pipe that are connected together to stop any ground, mineral-y stuff from coming along for a ride with the water (like it’s supposed to).

The plumbing system also has a heating element in it. this heats up some of the water as it travels towards its destination: your dirty dishes. here’s how that works: coldish water goes into one end of something called “the main hot side heat exchanger.” inside is another piece of metal — it’s shaped like a T and it’s called “the heat exchanger”.

Cold water goes in the bottom of the T and hot water goes through the top. so as the warm water flows up through the pipe, it passes right by all those dishes that are sitting there waiting to get cleaned. while it does this, some of that hot water (which is now steam) gets turned into drops of mist or fog: humidity! yeah!

Turns out they control things like how much detergent gets added, when stuff happens during the wash cycle (drying & heating) and most importantly: WATER TEMPERATURE!! although we think of dishwashers as hot, as you can see from the diagram above they actually get pretty cold. for example, here’s a typical water temperature cycle:

Once the wash starts (that’s when you push that button on your washer) — the water in there is 104 degrees Fahrenheit. it goes down to 95 during pre-rinse & rinse cycles and then back up to 110 or so during use of the heat element.

At this point we should say “don’t touch this stuff” because it gets steamy. Although dishwashers are safe to run, taking things out of them when hot could be dangerous (as we know from some bad stories). Also: don’t put any dishes in while it’s still heating up because you’ll probably burn yourself!

Pipes, hoses & other stuff: if you already know about plumbing systems then you can probably tell us a lot more than we could ever tell you. so instead of telling what’s inside your dishwasher (there are lots of things in there) let’s talk about the parts that connect it to all the other parts.

At this point I’m going to pretend that we’re talking about a full-size machine that connects the sink from above and has an external drain hose on the back side. but if your washing machine doesn’t look like this, don’t worry — most dishwashers work pretty much like this one (just smaller). Here it is:

The water supply comes into the bottom left and flows out the right side. there’s a filler hose on the left that you use to fill up your machine with water before each wash. the drain pours down into a larger pipe and then goes along until it reaches the garbage disposal — this is how all of your dirty water gets rid of itself (and you probably already know what happens to most of it).

When you’re ready to empty out your machine, just press that drain button (or “open” if yours doesn’t have one) and everything comes rushing down!

In between is something called an “accumulator.” turn off both the hot & cold supplies at their sources first (don’t mess around in there!). Now take a look at where they meet up in the middle of your washer. There’s a trap right in the middle and then you should see two hoses coming out on opposite sides. They should look like this:

Connect these to a big basin (basins are bowls) — one can be under your sink where all that plumbing comes together, or you might have something like this already built into the countertop. If you don’t know what I’m talking about… that’s okay; just call a plumber!

More stuff: so far we’ve covered pretty much everything about water usage & flow control and now we’re going to finish by taking a quick look at some other stuff that either heats up or cools down during the wash cycle. If you want to see how the heating element works, just clean up all the dishes and throw out some hot water in the sink.

Turn your faucet so that there’s a small stream of water flowing into that drain — now go look at the bottom of the disposal. You should be able to see a long coiled wire coil wrapped around an iron rod (or something like it). As this thing gets hot it starts to bend over & over… making larger & larger circles.

This is essentially what happens inside your wash machine when they build it with something called an “induction coil.” instead of using electricity (like we do for our stoves), they use heat by sending an alternating current through a metal object!

Because these coils are positioned right inside your dishwasher, all you can see is a device with lots of dials & buttons. But this is what controls the amount of heat being applied to your dishes!

The other thing we wanted to show you was the air dryer. if you look at the back wall there should be something like this:

This is just something that hot air comes out of so that it will dry off your dishes (along with anything else wet) while they cool down slowly — as opposed to letting them sit in the drying cycle for too long which would result in more water left on them than normal.

Some machines even have an “air-only” option where no drying takes place. either way, those devices don’t usually arrive in the box until they’re needed (usually after your warrenty ends )!

What are some dangers of dishwashers?

How Dishwashers Work

Dishwashers can help you avoid many germs, but there are still a few dangerous situations to watch out for. Always pay close attention while your dishwasher is running. If something is stuck in the machine, it may prevent the door from closing properly and cause injury if someone opens the door while it’s washing.

While dishes usually do not stack themselves, kids often like to play inside closed dishwashers when their parents aren’t looking. Keep an eye on young children when you open your dishwasher or turn it on so they don’t climb inside.

Finally, water inside a dishwasher can get very hot! When loading glasses or any breakable items into your machine, make sure you open it gently. Always keep a safe distance and make sure children don’t touch the door or open it while the dishwasher is running!

Tips and tricks on using dishwasher.

The dishwasher is often the best option for cleaning dirty dishes and small kitchen appliances. However, it can do more than just clean your dishes. Here are some tips and tricks to help you get the most out of your home’s built-in or portable dishwasher.

Wipe down items before placing them into the dishwasher to reduce water spots on easily scratchable surfaces like glasses and plastics. Spray a non-abrasive all purpose cleaner onto any nooks and crannies on plates, cutlery, cups and bowls prior to running a cycle; this will ensure that no food particles remain behind for ‘hard water’ deposits to build up over time.

You may also wish to run your very hot water tap for a few minutes before starting the dishwasher to ensure that no hard water deposits are present in the internal pipes of the dishwasher. Always make sure there is enough room in the soap tray prior to placing plates, cutlery or cups inside; if space is tight, you may risk damaging your dishes or glasses and will also be unable to fill up all compartments with dirty dishes.

Make sure you’re loading items into the machine correctly. Items should not be too close together – this could result in chipped or broken glasses or scratched surfaces on ceramic crockery; it’s also important to make sure that items such as plastic containers are placed onto the recommended rack when cleaning them. Dishwashers can help prevent fires!

It’s very important to ensure there is no food on any items which are being washed in the dishwasher. Wet sponges and cloths left in the machine can potentially cause fires if they come into contact with an electrical component inside the machine or underneath a base.

Make sure you place plug-in appliances like kettles, coffee machines, slow cookers and hot water bottles onto the bottom rack of your dishwasher once they have been used; this will prevent a fire occurring within these appliances due to heat from other dishes above them rising up through the cable holes within the racks.

If dirty cutlery has been placed into stagnant water in a sink prior to running your dishwasher, it may be filled with bacteria from that water. This bacteria can potentially cause food-poisoning. Ensure that cutlery and dishes are thoroughly dried before placing them into the machine or they might not come out clean and may cause an odour inside your dishwasher.

You should also ensure that any juices from meat products have either been fully drained off or have not seeped to the bottom of plates; this will prevent staining, especially on glass items. If after several uses you find that your glasses are coming out streaky after being cleaned in your dishwasher, check to see if there’s detergent residue at the bottom of your bottle; you may need to adjust how much is used per wash or use a different type altogether (eg liquid instead of powder).

How to clean the dishwasher?

The most efficient way to clean it is when everything has dried out and cooled down.

Clean the inside of your dishwasher with a mix of baking soda and vinegar, which will neutralize the bad smells that have built up. Keeping your kitchen appliances clean will keep food from building up on them and creating more odors, as well as keeping them in good working order.

If you don’t want to use vinegar, or it doesn’t work for you, use lemon juice instead. In some cases bleach can also be used safely but rinse well afterwards to make sure there isn’t any residue left behind that could damage your dishes if they are washed afterward.

If you need to clean between these components, spray a mixture of water and white vinegar on the surfaces and use a clean rag or sponge to wipe.

You could also boil a pot of water on the stove with baking soda added to it, then pour it into your dishwasher before running through another cycle in order to get rid of any smells. Baking soda is very good for this purpose because it will soak up odors very effectively.

Because these ingredients are mild enough not to harm any plastic components you can even just put your dishwasher on its regular cycle with water and vinegar or lemon juice added instead of using baking soda if you want something that’s more natural, less expensive, or if you don’t have any baking soda on hand. If the smells persist after doing this you may need to replace some parts in your dishwasher.

You will also want to wash the racks, trays and other components that go on the top of your dishwasher by hand as well. It’s best to do this immediately after running through a cycle so they are still wet from being washed in the machine.

You can rinse them off and then simply rub them clean with a sponge or rag using soap if needed, though usually just rinsing is enough to get all of the food off them. If you need to soak one of these items overnight in order to remove stubborn stains, it’s fine to do so. Just make sure you let it dry completely before putting it back into the machine or else mold might begin growing inside your dishwasher.

Clean Your Dishwasher By Adding Vinegar

Vinegar is an excellent cleaning agent that you can also use to keep your dishwasher clean and smelling fresh. Simply fill the detergent compartment in your dishwasher with white vinegar. Run through a cycle without any dishes inside, and then shut off the machine after it’s done running. Do not open up the machine during this procedure.

The smell of vinegar will disappear within a day or so of doing this step; however, if you find it too unpleasant to run for long periods of time because of the odor, try using lemon juice instead. The citric acid content in lemon juice is quite high which makes it better for removing build up than most other juices and therefore easier on your dishwasher as well as more effective at getting rid of bad smells.

If this doesn’t work, you can also use baking soda instead. Just follow the same procedure, but add a cup of baking soda as well. If your clothes are coming out looking dingy or musty smelling after using the washing machine to do laundry, there’s a good chance that some mildew has built up on it or in it during storage and you need to prevent this from happening with your dishwasher as well.

Simply run an empty cycle every month or two in order to get rid of any mildew that might have grown inside your dishwasher because of moisture due to it being left unwashed if possible, and wipe down the insides when necessary with vinegar so mold is less likely to grow there as well.

You can also use a mixture of white vinegar and water to soak the washer hoses and any other components that may be difficult to get to in order to remove stubborn stains from them. Just pour the solution on, leave it for several hours or overnight if necessary, then wipe off with a clean rag before rinsing thoroughly with water.

If you are doing this often in order to keep your dishwasher running well or because you have hard water deposits, consider investing in a whole house filtering system that will eliminate these kinds of problems completely. You can read about my recommendations for whole house filtration systems here .

Clean Your Dishwasher By Adding Salt And Vinegar

Accumulated food particles and residues along with mildew that grows in your dishwasher can lead to bad smells inside the machine as well as make it less effective overall. Luckily, getting rid of this is quite easy to do without having to use harsh chemical cleaners or spending lots of money on special products you buy at the store. You probably have everything you need right in your kitchen.

Vinegar and salt are both great cleaning agents that will help you kill germs naturally and get rid of old food residue that might be causing odors. Vinegar also helps remove mildew and its nasty smell, while salt is a mild abrasive cleaner that’s very good for cutting through grease and oil buildup as well as other crusty substances that may have accumulated inside of your dishwasher over time.

Simply add a cup of white vinegar and a few tablespoons of coarse salt to your dishwasher. Then run the machine through one cycle with hot water only without any dishes inside. This should get rid of most odors and stains as well as help the machine run more efficiently overall because you will be removing old gunk that could have built up on components in the past, clogging pipes for example or making it harder for water to flow properly throughout the system.

If this doesn’t work, try adding baking soda instead of salt since it is also abrasive. Just make sure not to mix too much baking soda at once into your dishwasher or else you will end up with a really sudsy mess on top of everything else. You don’t want this to overflow in the machine.

If you want to add more than just salt and vinegar, try adding some lemon juice as well. The citric acid will help remove odors even better than vinegar alone without leaving behind the residue that vinegar can sometimes cause, and it’s also a good natural cleaning agent.

If your glasses are coming out looking cloudy or if there are problems with water spots, chances are that there is too much calcium in your water which is hard on dishwashers as well as creates these kinds of problems by building up on dishes while they’re being cleaned in the machine.

You’ll need to have your water tested for this in order to find out exactly what kind of problem you’re dealing with along with how bad it is in order to find the best solution. You can read more about that here . If your water is hard, adding some citric acid isn’t a bad idea since it helps cut through these deposits and remove them so your dishes come out looking clean without hard water stains or cloudy spots on them.

Avoid Using Jet Dry and other Dishwasher Detergents with Silicone Ingredients

Cleaning products like Jet Dry are great for making things look shiny without having to use too much elbow grease, but they also contain silicone which can lead to clogs down the road as well as cause trouble with many other components within your dishwasher over time.

It’s not recommended that you use this kind of product at all because of how harmful it really is even though it is easy to obtain and not terribly expensive, but if you just can’t avoid using it (and probably will use it every once in a while), make sure that you never pour the product directly into your dishwasher.

Instead, try measuring out about half of what the bottle recommends and then adding that amount through the detergent or rinse aid compartment instead of pouring it inside. This should help reduce clogs because less Jet Dry residue will be left behind within the machine , and this will also prevent any build up from occurring between components as time passes by since there will be much less silicone present in general .

You want to avoid getting rid of all traces though because some residue really is needed for things to work properly. In summary, silicones are harmful and will cause clogs over time, but if you can’t get rid of them entirely, it’s a good idea to keep their amount down as much as possible through things like this method.

An alternative that is gaining popularity among many new dishwasher owners is the use of baking soda instead. It’s cheap and readily available at local grocery stores, so there’s really no reason not to give it a try instead of Jet Dry or some other brand which contains this potential problem in its ingredient list.

For more information on how to prevent clogs from occurring within your machine and what steps you should take if they do start even though you’ve been careful about using too much dishwasher detergent containing silicone ingredients , check out the article here .

Unfortunately, it’s hard to tell you simply how much baking soda to use because this depends on a variety of factors such as the amount of dirty dishes that you have, the hardness of your water, and so on. The best thing to do is try adding some in shorter increments until you’ve found the right amount for your machine and habits since they all work differently from each other.

You don’t want to use too much at once because then it will probably start clogging up your machine when bubbles begin building up inside due to not enough water being able to circulate past them through the filter. However, if you only add a little bit at first and then wait a while to run another cycle just in case anything gets caught in the filter, it should be fine.

If you find out that you’ve added too much, then simply wait for the machine to cycle on its own until the bubbles have gone away and then clean out any residue left behind in order to remove clogs later down the road when things might start getting worse while at the same time making sure your dishwasher will continue working properly.

If you use Jet Dry or some other product with silicone within it, follow these steps instead:

1. Add about half of what is recommended through your detergent compartment instead of pouring the product directly into your dishwasher as we talked about above .

2. Run a normal pre-rinse cycle without any dishes being loaded , and then run a normal cleaning cycle afterwards .

If steps 1 and 2 still don’t get things working properly, then you can try the following as a last resort:

3. Empty your machine of all clean water with an aquarium pump. Pour baking soda through the detergent compartment (to clear out any residue), run a short cycle to dissolve it, and then dump everything down the drain. Run two normal cycles afterwards in order to “reset” your machine and remove clogs , but make sure that you only use half of what’s recommend for your detergent since we talked about this above already .

If you are unable to access an aquarium pump or if these steps do not work like they should after trying them several times over, please call your dishwasher’s manufacturer or find another nearby service center where you can have a professional look at it for you as this is something that they should be able to fix relatively quickly and easily.

Remember, clogs are not always due to the amount of detergent added , so don’t hesitate to ask around or try other things out if the one we’ve been discussing in this guide hasn’t worked.

Common question when using dishwasher.

1. How much detergent should I use in my dishwasher?

There are a number of different brands out there, and many of them work great when used correctly , but as you may have already noticed, some of them will require more than others. In fact, if the instructions on the bottle don’t say how much to add for the cycle you’re using, then chances are that it will take either half or twice as much compared to another brand’s recommendations.

Why is this? Well, all dishwasher detergents contain different amounts of water softening agents like sodium silicate or even silicone oil . Both types can help improve the quality overall whenever they are used within recommended limits , but both also have their drawbacks.

Dishwasher Detergent That Contains Silicone Since we’ve already talked about this in our previous blog post , we’re not going to reiterate everything that was said there, but lets just say that using too much detergent with silicone can end up clogging the dishwasher’s jets . If you don’t know if your brand happens to contain silicone or not, then reading the label is usually a good idea for most people.

When it comes to how much detergent should be used for each load, it also depends on how many different types of utensils and plates are being washed by comparing them against one another since those made from plastic tend to require more than those made from something else like china or glass. The same goes for the hardness of the water being used to wash dishes in since setting it to a lower level will usually allow some extra detergent in.

The following guide can be used as a reference, but please keep in mind that there are certain settings on dishwashers that may require more or less depending on how you have them configured . If you don’t see your brand listed below, then simply refer to our previous article for more information instead which has a good number of common brands already covered with helpful pictures showing how much is needed per cycle type.

Pots and Pans – 2 tablespoons

Plastics – 1 tablespoon (3-5 for very hard water)

Dishes & Glasses – 3 tablespoons   *(#19, 2-4 for very hard water)

China – 2 tablespoons   *(#3, 3-5 for very hard water)

Stainless Steel – 1 tablespoon

2. What are the common issues you have with your dishwasher?

a. Not cleaning dishes properly:

Your dishwasher may have a faulty pump, or the spray arms may be clogged with food debris and need to be unclogged. It could also have a timing issue so that if it is set to run for too long it will dry instead of wash, but this would require troubleshooting by a plumber.

b. Leaking:

This can be for a few reasons, but the most common are that there is inadequate slope in your dishwasher drainage pipe or improper installation of overflow tube assembly on the door of the machine (this should be on an angle), and/or insufficient seal around tub to interior cabinet wall.

c. Dishwasher doesn’t dry properly:

This can be caused by minimal flow from the water supply line, improper installation of a control valve to the inlet hot water line, faulty dishwasher main board or faulty door seal.

d. It makes strange sounds:

There are several things that could cause this problem; sound is produced from vibrations in pipes, pumps and motors. The first thing to do is make sure the dishwasher you have isn’t mounted on a wood floor, so some of the sound travels through flooring and walls.

If it is mounted on a wood floor or there are other vibration sources (such as waterbeds), then there are several things that can be causing this issue, including worn bearings, a bad impeller (impellers are located on the front of the motor in most models), a faulty motor or loose pulley. If it is not caused by any of these things, I would recommend having your dishwasher looked at by a repair technician to rule them out of investigation.

e. Scratches on dishes:

This can be caused by several different things, including a faulty spray arm or bad filter screens. To check if the screen is defective, you would need to remove and clean it. You should also look for any scratches that might have been on your dishes as well, these would be a manufacturer defect.

If there are no scratches or marks from manufacture, then you’re more than likely dealing with a defective screen, and should contact the manufacturer for repairs. Of course if your dishes are new it could be that they need to be broken in (this is especially true when it comes to anything made from glass).

3. How often should we clean the dishwasher?

I would recommend once per week, as hard water will cause deposits on inner surfaces and these will not only lead to your dishes coming out dirty, but will eventually lead to costly repairs.   We get asked all the time – what dishwashing detergent is best? We have been using the Cascade Complete Actionpacs for years and we love them. The tabs dissolve quickly and clean off all the food off of your dishes, cups, etc. This is our favorite way to wash our dishes!


Dishwashers are one of the most common household appliances. Whether you’ve just bought your first dishwasher or have been using them for years, there are a few things that everyone should know about these machines. Through this post, we hope to introduce some information on how they work and provide tips and tricks for caring for them along with helpful information their use.
