Dishwasher Heating Element
The heating element is responsible for reaching the thermal gates required by the control logic to advance the cycle. If the element is open-circuit or has developed a high-resistance scale buildup, the water temperature never reaches the set point, causing the dishwasher to remain in a 'thermal hold' wash state for hours. Replacing the element restores the thermal ramp rate required for the software to progress.

Optical Water Indicator (OWI) Sensor
This component contains both the turbidity sensor and the thermistor (temperature sensor). If the thermistor is biased or reporting an inaccurately low temperature, the control board will continuously attempt to heat the water, extending the cycle. Additionally, if the turbidity sensor is fouled, the logic assumes the water is still 'dirty' and adds repetitive rinse and wash cycles.

Main Electronic Control Board
The control board contains the high-amperage relay that closes the circuit for the heater. On this specific platform, solder joint fatigue or relay contact pitting often prevents the element from energizing despite the element itself being functional. This results in the same 'thermal hold' behavior where the machine runs excessively long without ever reaching the required temperature to finish.
