BoilerFaultCodesTechnical description
Failure during operation – re-ignition unsuccessful
What causes this fault?
This fault occurs when the boiler successfully starts but lose its flame while it is trying to heat your home or water. The most common reasons are a temporary interruption in the gas supply, a blocked flue, or internal components like electrodes becoming too dirty to detect the flame. It can also be caused by a buildup of debris in the condensate trap preventing the burner from staying lit.
This fault is more common in winter, as frozen condensate pipes can cause a backup of water that effectively 'drowns' the flame.
Engineer required
This is a high severity fault. Stop using the boiler and call a Gas Safe registered engineer. Do not attempt gas-related repairs yourself.
