Commercial Dishwasher Instructions

Commercial dishwashers are heavy-duty professional dishwashers commonly used in restaurants and other businesses. Most commercial dishwashers are used much like their domestic counterparts, though maintenance on the commercial washer is a bit more extensive. Learning to use and care for your commercial dishwasher takes just minutes.

Setup and Use

Before using your commercial dishwasher for the first time, you must set the water softener, fill the salt reservoir and add rinsing and cleaning agents. To set the water softener, turn your commercial dishwasher off and set the program selector to "Stop." Follow the prompts on your commercial dishwasher to set the water softness level.

Fill the salt reservoir with 5 1/2 pounds of salt. For best results, use a coarse-grain reactivation salt. Do not attempt to use gritting, table or agricultural salt in your commercial dishwasher.

Fill the appropriate reservoir of your commercial dishwasher with a rinsing agent to prevent water spots from forming on dishes during the drying phase. Be sure to use a rinsing agent that is specially formulated for commercial dishwashers.

Add liquid or powder detergent to the appropriate compartment in your commercial dishwasher. Never use detergents formulated for domestic dishwashers in your commercial dishwasher.

When loading your commercial dishwasher, situate the dishes so that every surface can be reached by the water jets. Do not crowd dishes or they will still be dirty at the end of the washing cycle. Load smaller, delicate items such as cups, saucers and glasses into the top rack of the dishwasher. Larger, heavier items such as plates, bowls and saucepans can be loaded into the bottom rack.

To operate your dishwasher, turn the program selector knob to the desired washing program, choose your drying preferences and press "Start."

Care and Maintenance

Proper care and maintenance will help ensure that your commercial dishwasher continues to function at its best. Proper care and maintenance include keeping the inside and outside of your commercial dishwasher clean. Should the outside of your dishwasher need to be cleaned, wipe it with a cloth that has been dampened in a solution of mild soap and water. Never use harsh chemical products to clean your commercial dishwasher, as they may damage its surface.

Periodically inspect and clean the filters in your commercial dishwasher's wash cabinet. Keeping the coarse, fine, flat and micro filters clean is essential for optimal operation of your commercial dishwasher. Remove all of the filters and clean and dry them before replacing.

The spray arm of your commercial dishwasher should also be periodically inspected and cleaned. Unscrew the spray arm, rinse it clean of any particles and reattach.
