What to check when buying a used commercial dishwasher

Choose a used commercial dishwasher around the items you wash and the demand during your busiest service. Check the basket dimensions and loading height against your largest plates, utensils and containers.

Ask to see a complete wash cycle and examine the results instead of relying on the machine simply switching on. Look for leaks, damaged baskets, blocked wash-arm jets and visible limescale inside the wash chamber.

Confirm the electrical supply, water connection and drainage arrangement, including whether a drain pump is needed. Ask your installer which water-treatment system suits the machine and your local water conditions.
