Dishwasher Heating Element
The heating element is responsible for providing the thermal energy necessary for flash evaporation. Over time, the resistive coil inside the element can fracture due to repeated thermal expansion and contraction cycles, resulting in an open circuit. Without this heat, the air temperature inside the tub remains too low to hold moisture in a vapor state, causing it to condense back onto the dishes.

High-Limit Thermostat
This bi-metal safety component is designed to interrupt power to the heater if it detects an overheat condition. If the internal contacts fail in the open position or the bi-metal strip becomes decalibrated, it will prevent the heating element from energizing even when the control board requests heat, leading to a complete failure of the drying phase.

Rinse Aid Dispenser Assembly
Modern dishwashers rely on rinse aid to reduce the surface tension of water, allowing it to sheet off surfaces via the Leidenfrost effect during the final heated rinse. If the dispenser actuator or gasket fails, the water remains in droplets which possess higher thermal mass and are more resistant to evaporation, resulting in wet dishes and spotting despite a functional heater.
