KP Compass Safe Service Practice Test

When water is too hot in a dishwasher, which statement is true?

Dishes may crack due to heat. The foods may bake onto the dishware. The cycle's energy use decreases. The dishwasher will refuse to start.

Correct Answer:

The foods may bake onto the dishware.

Explanation:

When water is too hot, the cycle dries surfaces quickly and can cook any remaining food particles onto the dishware, causing them to bake on. The heat doesn’t reduce energy use; in fact, hotter water generally uses more energy. A dishwasher starting or refusing to start isn’t usually driven by the water temperature in this way, and while extreme heat can stress dishes and cause cracking in some cases, the most direct and common result described here is baked-on food residue. So this overheat effect best explains why the foods may bake onto the dishware.
