Which outcome is most likely when dishwasher water is too hot?

• A. The foods may bake onto the dishware.
• B. Dishes will come out with an oily film.
• C. Detergent will foam excessively.
• D. The cycle will take longer.

Answer: (A)

When water is much hotter than intended in a dishwasher, the heat can cause residues on food to dry and bond to the dishware, effectively baking onto the surface. This happens because the intense heat speeds evaporation and solidifies fats, sugars, and proteins onto the dishware before the wash action can lift them away, leaving stubborn stickiness that looks baked on even after a cycle. That’s why this outcome fits best: you end up with foods that seem baked onto the dishes. The other options aren’t as directly tied to overly hot water—the oily film usually points to detergent or rinsing issues, excessive foam comes from detergent behavior rather than temperature, and a cycle taking longer is not typically caused by water being too hot.
