Washer shows E09 and may trip the household breaker or stop immediately after starting a cycle.

Safety first: Switch off the circuit breaker and unplug the washer. Do not reset the breaker repeatedly without finding the cause.

Step-by-step checks:

• Access the heater: Remove the rear panel to expose the heater terminals and wiring.
• Inspect for moisture: Look for signs of water leakage around the heater seal or terminals. Dry the area thoroughly and identify any source of leaks (e.g. door seal, tub crack).
• Check wiring: Ensure heater wires are not pinched or rubbing against the metal cabinet. Repair or reroute as needed.
• Test for earth leakage: With a multimeter, measure resistance between each heater terminal and the metal chassis. Any low resistance (e.g. under 1 MΩ) indicates insulation failure; replace the heater.
• Replace heater if faulty: Remove and refit as described in the E05 procedure, ensuring a watertight seal.

Note: If the heater tests good but the breaker still trips when heating should start, the PCB or wiring harness may be at fault and should be checked by a professional.
