“If there are too many dishes loaded in the washer, the chances of overheating go up greatly,” says Mark Stoltzenburg, an HVAC/R-MAR program director/instructor at the Midwest Technical Institute. “Many of the components inside have a safety device to protect them from overheating, but by overloading the dishwasher those devices have a harder job, and component failure is more likely.”
Using the delay cycle
“Even if the delay start option is invented to deliver comfort and convenience, in a mechanical point of view, your appliance works harder to warm the water to the required temperature for dish-washing,” Smith says. “A harder and longer operation always impacts service life and reliability.”
Forgetting to empty the food trap
Extra food particles that don’t come off dishes from an initial rinse gets collected in your dishwasher’s food trap. To avoid clogging, Family Handyman recommends lifting up the arm at the bottom of your dishwasher to empty the food trap about once a week. It might be making your dishwasher mouldy.
