How To Fix A Commercial Dishwasher That Won’t Clean Dishes?

You need clean dishes to serve your customers food, but your commercial dishwasher is showing problems and the dishes are not coming out clean. Your staff member will have to clean dishes manually when the kitchen runs out of clean dishes, which will increase the workload and slow down your service. Therefore, you must have it fixed by a commercial kitchen appliance repair expert quickly.

In case you want to do something yourself, here are some things to check if your commercial dishwasher won’t clean dishes.

Change The Detergent

A detergent makes it easier for water and the dishwasher to clean the dishware. However, some detergents may not go well with the dishes, types of stains, or the type of dishwasher you have while some detergents are outright bad.

So, your commercial dishwasher not cleaning dishes may be because of the detergent. Therefore, try changing the detergent and determine the right amount you need to add for each cycle.

A simpler way to choose a dishwashing detergent is to check out which detergents similar restaurants or canteens are using and use the same one if your dishwasher is also similar.

If you want to know which detergent is the best, it depends on various things. However, a good detergent should produce less foam, could break down dirt on the dishware, could remove scale, and must not be corrosive or have volatile substances.

You should make the decision factoring in your dishwasher whether it’s a high-temperature dishwasher or a low-temperature one. You will need a sanitizing chemical for low-temperature dishwashers while for high-temperature models, you don’t need any.

If you don’t want the slightest change in your food or drinks’ flavor, don’t use low-temperature sanitizers and use a high-temperature dishwasher.

Use Rinsing Aid

If the dishes come out comparatively clean, but you notice spots on them later, they may be due to hard water or mineral deposits on the dishware. You can add a rinsing aid in the final cycle to avoid these marks on the dishes, glasses, and other items.

A rinsing aid is 90% water and 10% other things like alcohol, citric acid, etc. It reduces the surface tension of water so it’s removed from the dishes more easily. As water is removed from the dishes before drying, the minerals that cause spots are also removed with water.

You should correctly determine how much rinsing aid to use depending on the dishwasher and the hardness of the water.

Install A Water Softening System

The last point was about removing mineral buildup on dishes that is caused by hard water. However, hard water also causes other problems even if you use a rinsing aid for resolving one problem.

Hard water reduces foam formation and thus reduces the cleaning ability of water even when detergent is used. This may be why your commercial dishwasher is not cleaning dishes well enough. You will need to use more detergent than usual and may have to increase the wash cycles to get clean dishes which will reduce the efficiency of the dishwasher and increase dishwashing costs.

A better method of fixing this problem is the installation of a water softener. It’s a type of water filter that gets rid of minerals from water which are responsible for scale buildup on dishes.

As you will use a water softener, your detergent will work better, your dishwasher will be more efficient, and you won’t need to use large amounts of rinsing aid.

Clean The Dishwasher

Hard water doesn’t only cause spots on dishes but also leaves white scales or limescale inside dishwashers and other appliances as well. This can clog critical parts of the dishwasher that help in cleaning the dishes.

So, whether you install a water softener or not, make sure you or your staff clean the dishwasher at the end of every business day. During the cleaning process, remove food particles, gunk, and debris from the dishwasher first before thoroughly rinsing and washing the interior of the dishwasher with warm water. Then, allow it to drain.

After this, clean the spray nozzles with white vinegar to reduce limescale buildup on them. Empty and clean the filter of your commercial dishwasher. Afterward, move to the wash and rinse arms of the dishwasher and clean them.

Regular cleaning and descaling a dishwasher are two different techniques. You must be cleaning your dishwasher every day as mentioned above while descaling should be done depending on the hardness of water in your facility and how quickly the limescale layer forms on the interior parts of the dishwasher.

For descaling a commercial dishwasher, follow these instructions:

  1. Fill your dishwasher with water.
  2. Mix the descaling product in the water.
  3. Let it be for one hour.
  4. After an hour, run a complete wash cycle.
  5. Check the dishwasher for limescale. If there is still limescale, repeat this process.
  6. Once you have checked that there is no limescale left, drain the dishwasher.
  7. Fill the dishwasher again for a final rinse cycle.
  8. Let it air dry.

Rinse The Dishes Before Putting Them In The Dishwasher

This is a common practice in most professional kitchens, but in case your staff is not doing it, instruct them to do so. Rinsing the dishes before putting them in the dishwasher makes cleaning easier for the dishwasher, the dishes come out squeaky clean, and the dishwasher doesn’t get too dirty too quickly.

When rinsing or handwashing the dishes before their wash cycle inside a dishwasher, don’t use a household detergent because it can lead to foam formation inside the dishwasher. This foam formation can affect the efficiency and washing capability of the dishwasher.

Clean The Spray Arm

You will be cleaning your dishwasher at the end of each day, but if your commercial dishwasher is not cleaning dishes and you want to try something yourself, clean the spray arm. It’s the component that spins and sprays water on the dishes. If it’s clogged, it will spray less or no water, so the dishes won’t be cleaned.

You can simply remove the spray arm from the dishwasher and manually clean it. If the dishwasher still doesn’t clean dishes and you notice it’s due to the spray arm, you will have to replace this component.

Check The Detergent Dispenser

The detergent dispenser is responsible for releasing detergent. A blocked or defective detergent dispenser will only lead to dirty dishes at the end of the wash cycle. So, turn off the dishwasher and check the detergent dispenser. Clean it and if it’s defective, have it replaced by getting help from an expert. Similarly, if your dishwasher has a rinse aid dispenser, check and clean it as well.

Moreover, you should also check other related components like the detergent dispenser’s door spring, the wax motor, and the bi-metal switch (older dishwashers).

Make Sure Your Dishwasher Is Filling Up With Water

During the wash cycle, the dishwasher must fill up with water. If it doesn’t, the dishes will be left dirty. This can be caused due to a faulty float, malfunctioning float switch, clogged or damaged inlet valve, or a bad door switch. Have an expert check these components.


The issue of a dishwasher not cleaning dishes can happen due to many factors. You should begin with smaller things like cleaning the dishwasher and then move to checking the components of the appliance. It’s better to leave this to a commercial dishwasher repairs Northern VA technician who will completely inspect the machine and perform repairs as required.



How To Fix Your Commercial Dishwasher?

A commercial dishwasher is used continuously during busy hours for ensuring clean and sanitized dishes. If the appliance shows problems, it can affect the workflow of your commercial kitchen. Your best option is to call in a commercial dishwasher repairs expert to inspect the unit and perform repairs, however, you can try some fixes yourself. Let’s look into some commercial dishwasher problems and their fixes.

Fixing A Commercial Dishwasher

Leaking Commercial Dishwasher

Door Seals

The doors of dishwashers also have seals. This is common in many appliances to seal air and moisture. In commercial dishwashers, a seal is to prevent water from escaping the unit. With usage, these rubber gaskets or seals become hard. When they do, they can’t keep water inside the appliance. In turn, water leaks out of the dishwasher during wash cycles.

So, inspect the seals of the dishwasher. If they are not soft or are damaged, consider a replacement. They should be replaced by a professional.

Water Inlet Valve

This is the valve that supplies water to your commercial dishwasher. Any problems with it will obviously lead to water leakage. You will notice a pooling of water near the appliance. So, check that the valve is fit and not loose. Then, look for cracks or damages on the external housing. Then move to the connecting hoses. They should be secured well. If the issue is anything other than a loosely fitted valve, consider a replacement of the inlet valve.


These are seals applied to the joints to make them watertight and airtight. Rubber and silicone O-rings are common. Both of these types deteriorate with time. The elasticity diminishes and the seals no longer remain effective.

They are used in various parts of a commercial dishwasher like the tap fittings, float valves, drains pump, rinse pump, and others.

You will need to check these components of the dishwasher to determine which O’rings are broken so you can replace them. This should be done by a professional.

The Commercial Dishwasher Not Draining

Drain Pump

If your commercial dishwasher is not draining water, the first part to check is the drain pump because it drains water from the appliance. Look for blockages in the pump. Moreover, check the pump for collapsed bearings. A sign of collapsed bearings is a noisy dishwasher. Lastly, the drain pump itself may be faulty.

After checking the above things, you should know that other components also impact the functioning of the drain pump. A control board failure won’t signal the drain pump to drain water, so check the control board, select switch, timer switch, and inlet valve as well.

Drain Impeller

Impellers in a commercial dishwasher create a sucking force for spraying water or other solutions on the dishes or draining the water. A spray impeller sprays water while a drain impeller drains water. If your commercial dishwasher is not draining water, check the drain impeller.

A drain impeller wears with age and can be damaged if any object comes in contact with it. A professional can determine if the drain impeller is fine or needs to be replaced.

Rinse Pump

If you checked the drain pump and it was fine or it was clogged or faulty and you replaced it, but your commercial dishwasher is still not draining, check the rinse pump. It can also wear over time and fail.

So, look for signs that indicate you need to replace the rinse pump. The first is that your dishwasher won’t drain properly. The second sign to look for is noises coming out of the pump during the end of a wash cycle.

The Commercial Dishwasher Is Not Filling

Water Inlet Valve

A water inlet valve has a filter that removes various kinds of particles from water. Once it becomes clogged with particles, the dishwasher will take more time for filling or won’t fill. This filter is easy to access so check the filter and clean it.

Float Switch

Typically, it should move freely. However, if it sustains damage due to age or any foreign objects, it can stop the water from flowing. So, the dishwasher won’t fill.

Timer Control

It controls various components of your dishwasher. Whether your commercial dishwasher is not draining or stops filling, it won’t start or is showing other issues, don’t forget to check the time control and make sure it’s functioning properly. Hire an expert who can replace it.

The Commercial Dishwasher Won’t Start

Power Check

Check if your appliance is plugged in. You should also check the circuit breaker if it’s not tripped. These actions should ensure that your control panel receives power.

If your control panel has power and the dishwasher is still not starting, you should check the doors.

The Doors

The doors of a commercial dishwasher have relays that signal the machine to start. If the door is not closed, the dishwasher won’t start. This is why the dishwasher starts functioning when you close the door.

However, if you shut the door properly and the dishwasher is not starting, the relays connected to the door may be malfunctioning. They are not signaling the control board that the door is shut and begin the operation. So, replace the relays.

Motor Relay And The Motor

The motor relay is responsible for turning the drive motor on and off. So, any malfunction with this relay will result in the drive motor not turning on. Therefore, the dishwasher won’t start.

However, if all the relays are functional, then the drive motor itself can be faulty. This should be checked by a skilled dishwasher expert.

Wet Dishes

Overloading Or Poor Stacking Of The Dishwasher

Dishes are dried by the circulation of air. An overloaded dishwasher will have dishes stacked too near that won’t have enough space for air circulation. So, they will come out wet after the wash cycle. Moreover, improper stacking of the washer will also give similar results.


The thermostat in a commercial dishwasher regulates the temperature of the water that is used for rinsing the dishes. It tells the heating element how much to heat and when to turn it off. If the thermostat is faulty, the water will either not heat or overheat.

Heating Element

Heating elements heat the water to the temperature you set using the control panel. These instructions are sent to the thermostat and it signals the heating element to heat the water and reach the right temperature.

If your thermostat is fine, then the heating elements could be malfunctioning. The heating element should be checked by a professional to know if it’s faulty.

However, there is a sign that can show you when to give attention to the heating element as well along with the thermostat.

If your commercial dishwasher overheats water, it can be a thermostat issue because the heating elements are still heating the water. But if the water isn’t heated at all, it can be either the thermostat or the heating element. So, check the heating element only when the water is not heating at all.


A commercial dishwasher can run into many kinds of problems, so you and your team should know some tips to fix the unit. But if the cause of the issue can’t be determined or you want to fix the appliance quickly, call in a commercial appliances repair Alexandria technician.
