The washer shows H2; this may indicate overheating or a 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 the heater and NTC: Remove the rear panel and check for limescale buildup on the heater (visible through the tub opening if removed). Replace a heavily scaled heater.
Test the 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.
