Viessmann 200 and 222 fault fault EE
At burner start, flame signal is missing or too weak
Gas boilerWhat it means
Burner in fault mode due to detailed code 132: at burner start, flame signal is missing or too weak
Likely causes
- Gas supply issue
- Faulty ionization electrode or connecting cable
- Ignition system issue
- Condensate drain blockage
Where to start
- Check gas supply (gas pressure and gas regulator)
- Check gas train
- Check ionization electrode and connecting cable

Safety: Isolate gas and power before you open the case. If you have been into the gas side, do a tightness test, and a combustion and flue check before you hand back. Gas Safe (UK) or RGI (Ireland) work only.
From the Viessmann manual for the 200 and 222 fault. Check the model on the data plate before you order parts.
