How to clean a commercial dishwasher?

The simple mistake of not cleaning a dishwasher can create an embarrassing situation and harm your business. Cleaning your commercial dishwasher daily will ensure it doesn’t get clogged up with gunk. Dishwashers don’t automatically clean themselves during the dishwashing cycle just because they are dishwashers.

Showers don’t clean themselves in use, actually becoming dirtier when you’re using them. Commercial dishwashers are also susceptible to this. It will lead to your dishes not getting cleaned if your filters and jets are clogged and the limescale accumulates. So it’s important to clean a dishwasher. In this article, I’m going to tell you how to clean a commercial dishwasher?

Do commercial dishwashers use detergent?

Do commercial dishwashers use detergent


In commercial dishwashers, the detergent and rinse aid dispensers are often incorporated into the machine and automatically add the solution when the cycle is complete. In contrast, under-counter dishwashers have a sanitizer pump, detergent pump, and rinse aid pump, so this is generally not an issue for vertical and conveyor dish machines.

It is mainly used to clean dishes in both low- and high-temperature dishwashers. Dishwasher Detergent is used to clean dishes in either type of dishwasher. Some commercial dishwashers accept powder detergent only, and some accept liquid or solid detergent. So commercial dishwashers use detergents.

Which detergent is best for a dishwasher?

DESTAIN – Commercial Dishwasher Liquid is something you should check out. Phosphate-free and made from a biodegradable mixture, it boasts of low toxic levels. Designed specifically for commercial machinery, this liquid detergent produces low suds. Liquid dispensers and detergent pumps are the best way to apply them.

So this dishwasher is best for commercial dishwashers. Because we must use an efficient detergent which cleans all components of dishwasher properly. Some dishwashers are too fast in chemicals that it could harm the components and make the dishwasher useless.

The amount of maintenance allocated to a commercial dishwasher determines whether it will last 10 or 20 years. Commercial dishwashers in high-volume establishments that are poorly maintained are typically lucky to last seven to ten years.

Those same commercial dishwashers will last around 15-20 years if cleaned and delivered regularly. So there are some ways to prevent build up in your dishwasher:

Turn off the power:

Whenever you clean a dishwasher, first of all, turn off the power. It is not only necessary for the dishwasher but also every electrical appliance. Because water can cause electric shock and become the cause of death. So plug out the dishwasher before cleaning it.

Commercial dishwashers automatically start when the door is closed so separate the adapter from the faucet also or turn off the power.

Remove food residue:

It’s very important to remove food residue from the dishes because these tiny particles of food cause clogging. If you put dishes in the dishwasher with food particles it will cause a hurdle in draining of water and results in clog of your filters and jets.

So before loading dishes into the dishwasher, scrape dishes spray them so that tiny particles of food are removed. So make sure dishes are always cleaned thoroughly before the dishwasher and sprayed with a spray cleaning agent.

Use the correct detergent:

Every detergent you use for dishwashing or your dishwasher is not the same as what you use for washing dishes. Follow the manufacturer’s instructions and choose the detergent recommended by them. Save some pennies by choosing a cheaper option as it will affect your reputation in the market.

So make sure you are using the right detergent. If you are using a glass washing or machine dishwashing detergent, you must use one with added phosphate (Not ordinary dish solvers).

Wipe down the interior:

When you are done washing dishes, clean the interior of the dishwasher. Unclog the filters or holes. If you do not wipe the dishwasher after washing the dishes then it would be the cause of vandalization.

So rinse the dishwasher with warm water and detergent while using a cleaning cloth or spray nozzle. So that it does not cause any problem in the future.

Drain the dishwasher:

Once you have cleaned the dishwasher from the inside, drain the tank and then fill it back up with water. Remove the cover of the dishwasher and let it air dry.

Do not put the cover of the dishwasher wet otherwise it would cause rust. Which is harmful to the dishwasher. So be careful.

Clean the spray nozzles:

Cleaning the spray nozzle is very important. Because hard water builds up on the nozzles. So use white vinegar to remove hard water from the nozzles. White vinegar is best as a cleaning agent.

Clean the screens, filters, and baskets:

So the next step is the cleaning of the screen. As we know the dishwasher glass screen helps to see us the wash cycle. If the screen is dirty then you could not see the dishes that either these are washing or not so for cleaning the screen using a clean cloth.

Now cleaning of filters and basket is also important as a screen. So clean the debris from the filter with a hand or brush. And then rub the filter with detergent using a brush for cleaning. Also, clean the baskets of the dishwasher using a brush or cloth.

Clean, wash/rinse arms and jets:

Clean the arms and jets of the dishwasher so that the water holes would be clear. Wash or rinse the arms and jet with warm water so that it would be easy to clean the water holes. Water holes are blocked because of food particles or debris. So if any part of them is damage replace it after cleaning.

Top off detergent:

Ensure that the feeder tubes run freely after you have filled them with detergent. Rinse the aid compartments after filling them with detergent. Both of these steps can help clean the dishwasher after each use.

Run a cleaning cycle:

Run a cleaning cycle after adding detergent to the commercial dishwasher. By polishing the interior of the machine one more time, not only it will prevent dust from accumulating inside the machine, but it will also give you the chance to listen out for unusual sounds or hurdles/problems.

Ensure the parts you removed while cleaning has been properly reinstalled if these issues occur. So whenever you clean a dishwasher, in the end, run a wash cycle so that you could know, is the machine is working or not.

Air out the machine:

Now finally the last step is to air out the machine. For this, open the dishwasher door or top of the dishwasher so that the air circulates and helps to prevent the bacteria buildup.

How to  descale your commercial dishwasher?

When hard water builds upon the components of the dishwasher, it would damage the dishwasher and cause failure. Hard water occurs because of minerals such as calcium and magnesium. Then these minerals harm the components of the dishwasher and do not let the dishwasher clean the dishes efficiently.
