Blomberg washing machine H1 error code
H1 means heater / ntc fault. The temperature sensor (NTC) is out of range, so heating is blocked or misread..
Often fixable at home · Fault type: Electrical/hardware
Safe checks, in order of likelihood
- Unplug at the wall for 10 minutes and retry.
- Run a warm programme and check if the wash heats.
- If H1 returns, the NTC sensor or its wiring is the prime suspect.
Call a professional when…
Reset first; then the NTC sensor is replaced. If the code returns after these checks, book a qualified engineer.
