  Heather JamesSep 5, 2025
  If the burner control unit in your Viessmann Boiler is in a fault state, here are some potential causes and solutions: * If valve 1 or valve 2 is leaking, replace the gas train. * If there is an internal fault and the fan cannot reach its set value, replace the burner control unit or fan. * If the safety chain has been opened, check the safety chain. * If there is an internal error in feedback from gas safety valves or the output relay does not respond, replace the burner control unit. * If the safety chain is 'live', check the safety chain. * If it is an EMC fault, have your system tested for EMC interference.
