Possible Causes

Stuck heater relay on main control, Faulty temperature sensing circuit, Shorted heater drawing excessive current, Wiring short to heater

Safety First: Unplug the washer; heating circuits are high voltage.

Inspect heater wiring: Check for melted insulation or signs of shorting to the chassis.
Test heater: Measure resistance and insulation to ground. Replace if shorted.
Control board inspection: If the heater is good, the main control's heater relay may be stuck or burned. Replace the main control board if confirmed by diagnostics.
