Hi. I've got a problem with a Baxi 105e that has stumped me. When running the DHW the burner ignites for around 12secs then goes out. Shortly re-ignites for 12 secs again and then goes out. This will repeat as long as the DHW is being called for. It also happens on the CH once the rads are up to temp. There are no lights flashing to indicate any warnings or faults either.
I have changed both temp sensors, flame sensing probe, checked the incoming power supply and all the obvious ones. I'm down to the problem being either the PCB, the plate heat exchanger requiring cleaning or the gas valve perhaps.
Has anyone ever come across this type of fault before and could you please help me out if you have?
Many thanks. Nick
