Washer shows H2; may indicate overheating or heater relay fault.

Safety Warning

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Heater relay stuck on PCB, Limescale buildup causing localized overheating, Faulty NTC giving incorrect readings, Wiring short causing heater to stay on

How to Fix / Troubleshooting

Safety first: Unplug the washer immediately if overheating is suspected (smell of hot plastic, excessive steam).

Step-by-step checks:

Inspect heater and NTC: Remove rear panel and check for limescale buildup on heater (visible through tub opening if removed). Replace heavily scaled heater.
Test NTC: As per H1, verify correct resistance and response to temperature.

If the heater is being energized when it should not be (live testing required), the PCB relay is likely stuck and the board must be replaced by a professional.
