Miele H 2455 B ACTIVE fault codes
Catalytic rather than pyrolytic — Miele’s product data describes it as PerfectClean with catalytically enamelled liners. The three pyrolytic codes cannot appear on it.
Codes on the H 2455 B ACTIVE follow the same Miele scheme as the rest of the range. Where a code behaves differently on this generation, the code page says so.
Miele fault codes
Every published Miele code. Open a code to see which models and years it applies to.
- F33The pyrolytic door lock will not open. One of only two codes Miele’s own manual acknowledges, and the one where cutting the power is the wrong instinct.Get it checked
- F32The pyrolytic door lock will not close, so the clean cannot start. Miele have you check the seal for a foreign object, which is often the whole answer.Get it checked
- F55The safety switch-off has operated after an unusually long run. Miele say the oven is ready for use again immediately — off, on, and carry on.Usually simple to fix
- F134The sensor is reading the cavity as too hot. Miele give no owner remedy for this one, and they conspicuously withhold advice they publish for a related code.Stop — call an engineer
- F23The pyrolytic clean never reached temperature, and Miele name the reason: too much loose soiling in the cavity. Clear the worst of it and run it again.Get it checked
- F44A technical fault, and Miele give the only reset duration they publish for an oven: 20 seconds off at the circuit breaker, not a plug.Get it checked
- F60Insufficient ventilation. Miele publish a free fix for this one: check the air duct is not covered or blocked, then disconnect the oven from the power and reconnect it.Get it checked
- F38An electronic module fault. One of only two Miele oven codes with no owner remedy at all — their answer is to book a repair, and nothing else.Get it checked
- F54The food probe is faulty. Pull it out of its socket and Miele say the message disappears — the oven works normally without it.Usually simple to fix
