​Monitor your machine to ensure dishes are clean

If your dishware and utensils aren’t as clean as they could be, they could sicken a guest (or at least leave them with a negative impression of your operation’s cleanliness). Make sure you maintain and clean your dishwasher to ensure it performs as it should. Ecolab advises to first avoid overcrowding the washer, since overlapping dishes can impede water flow. Then monitor the functioning of the unit by checking your gauges’ minimum temperatures, chemical concentrations and pressure measurements against those shown on the data plate. Clean the unit’s wash arms and jets regularly as they may become clogged with food or sediment buildup. Finally, Ecolab advises regular de-liming of the machine, since just one-quarter inch of lime scale can make a heating element use 39 percent more energy.
