In diagnosing dishwasher performance, which statement reflects too-hot water impact?

• A. Dishes will be untouched.
• B. The foods may bake onto the dishware.
• C. The machine will overcool the water.
• D. The cycle time will never vary.

Answer: (B)

Water temperature affects how soils behave during a wash. When the wash water is too hot, proteins and sugars can set and dry quickly, causing foods to bake onto the dishware rather than wash away. This baked-on residue after a cycle is a clear sign that the water temperature was excessively high. Dishes that come out untouched would point to no cleaning action at all, not to heat issues. The idea that the machine would overcool the water doesn’t align with how dishwashers heat and maintain temperature. And cycle time can vary with load and soil, so it isn’t fixed. So the observation that foods bake onto the dishware best reflects the impact of too-hot water.
