How to Clean a Commercial Dishwasher
If your commercial dishwasher isn’t adequately cleaning dishes, a simple cleaning of the appliance can save the day. Follow these easy steps and repair dishwasher for just one hour.
Step #1 Remove and Clean the Spray Arm
Remove the dishwasher arms and clean the holes from food debris or limescale, which is common in areas with hard water. It allows access to the appliance filter for cleaning.
Step #2 Submerge Spray Arms in White Vinegar
If you need to clean spray arms, even more, soak them in white vinegar to eliminate any remaining debris inside the holes.
Step #3 Inspect the Pump Impellers
There’re two pump impellers in a dishwasher: the wash impeller and the drain impeller. The wash impeller circulates the water and pressurizes the spray arms while the drain impeller drains the machine. Double-check them for damage and make sure they’re working adequately.
Step #4 Check the Food Grinder
The food grinder chops food particles remain on dishes, so they can easily pass through the drain part of the machine pump. If food debris isn’t finely chopped, the food particles could block dirty water from draining and more likely to be recirculated throughout the machine. Control the food grinder, and if it’s damaged, you must replace it as soon as possible.
Step #5 Remove Food Particles from Coarse Filter
This type of the filter is the mat at the bottom of the machine that collects debris that could block a dishwasher from draining. Use a Shop-Vac or similar products to eliminate existing food particles.
Step #6 Drain Reservoir Cleaning
Take off the cover of the drain reservoir and remove any food debris that has accumulated.
Step #7 Eliminate Residue
Mix baking soda and white vinegar to make a semi-thick paste. Spread this mix onto any residue with a brush and allow the paste to sit for 10 minutes. Then, use steel wool to scrape off the waste. Rerun this action until the bottom of the appliance becomes completely clean.
Step #8 Control the Water Inlet Valve
The water inlet valve is positioned at the front of the device and allows water to enter the appliance. Too much water will make water to flow out the machine while insufficient water produces poorly washed dishes. If the water inlet valve is blocked or damaged, it fails in providing adequate water levels in the appliance, and that’s why a machine isn’t cleaning well. If the inlet valve is blocked, replace it immediately.
If any of these tips and options don’t help, you must call authorized service or professional to pinpoint the “symptom” and to provide an adequate solution for your commercial dishwasher.
