Heater Assembly
The heating element is the primary component responsible for reaching wash and dry temperatures. When the internal resistive coil fails, the dishwasher stalls in its cycle waiting for the water to heat up, causing it to run for hours before eventually triggering the 'HE' error code. Replacing the full assembly ensures the heating path is restored.

Thermistor Assembly
The thermistor monitors the water temperature and provides resistance feedback to the main PCB. If the thermistor is out of calibration or faulty, it may report an incorrect temperature (too cold), preventing the timer from advancing to the next cycle stage.

Main Power Control Board
The main PCB contains the mechanical relay that switches high-voltage power to the heater. If the relay contacts have oxidized or the solder joints have cracked due to thermal stress, the heater will not receive power even if the element itself is functional.
