Before you begin putting the items in a dishwasher, it is important to make sure that you close the drain. After closing the drain, press the fill button and wait for the dishwasher to get filled.

Make sure that fill the water approximately 3 inches from the bottom of the pan. Once the water is filled, the next would be to check the temperature of the water.

Remember, the optimal temperature for water is about 140 to 155 degrees. After that, you may add detergent, additives, and sanitizer.

The first step was to prepare the dishwasher for washing and cleaning. In this step, you will have to sort out the pots, dishes, glasses, cups, pans, and plates.

For the plates, you must stack them from small to large. We know how the plates can have very strong food crusts if kept untouched for a long.

Since the commercial dishwasher cannot scrape off every hardy food crust, you can pre-rinse the dishes to ease the process of cleaning.

Once you have placed the dishes in the dishwasher, close the door and press the start button for about two seconds.

After the plates are washed, you can load cups and glasses in the dishwasher for washing. Feel free to repeat the process if required.

3. Draining and Cleaning Process

Once the washing process ends, turn off the power of the dishwasher. Then, lift the drain ball assembly and remove the pump screen. Finally, wash and clean the pump screen.

After the pump screen cleans up, place it back in the dishwasher. Don’t forget to repeat the same removal and cleaning process for the accumulator tray.

As for the last step, make sure to check the washing arms of the dishwasher. If the washing arms require cleaning, you can rinse them thoroughly before starting the next round.

A little pro tip is to operate the commercial dishwasher at a full load. It is because when the dishwasher works, it uses a lot of power and water. So you will successfully save water and power from waste by running the dishwasher at full load.
