Self-cleaning (pyrolytic) oven function not working (AEG & Neff)
✅ Safe to check yourself
This is a common, low-risk check most people can do safely. Always unplug the appliance (or isolate power) before touching internal parts.
Quick TipTake a photo of the appliance's model/serial number sticker now — you'll want it if this does end up needing a part or an engineer.
Pyrolytic self-cleaning ovens burn off food residue at very high temperature (typically 400-500°C) rather than requiring manual scrubbing, and the function refusing to start has a few genuinely common, checkable causes before it’s a fault.
What to check first
- Check the oven door is closing and locking fully — pyrolytic ovens have a safety door lock that engages during the cycle (given the extreme temperature involved) and won’t start the function at all if the door isn’t detected as properly shut.
- Check you’re not trying to run the function while the oven is still warm from recent cooking — some models require the oven to be at a safe starting temperature before pyrolytic cleaning can begin.
- Check for a delayed-start setting that may have been accidentally set, making it look like the function isn’t starting when it’s actually just waiting.
- Remove oven racks and accessories first if your manual specifies this — some models won’t start (or will warn you) if standard non-pyrolytic-rated accessories are left inside, since these aren’t designed to survive the extreme cleaning temperature.
When to call an engineer
If the door locks properly and accessories are removed but the function still won’t initiate, the door lock sensor or the control board’s pyrolytic safety circuit may have a fault — this needs a professional diagnosis rather than repeated attempts, given the temperatures and safety interlocks involved.
