Boiler fires and runs fine for 5-10 mins, then alternately cuts out and relights interminally until I switch it off. Will do the same after approx to 10 mins. The heat sensor has been replaced, a smoke test conducted and passed and the pump is working fine. I am now at a loss at what the problem could be. This is a Baxi Bermuda gas fired central heating back boiler with electronic ignition...any ideas?
Needs tune up change filter and nozzle and check electrodes are clean with no build up and clean out chambers

Think this post is in the wrong category!
sorry that was for oil --check the gas valve screen/filter for debris also valve internal pressure regulator spring may be failing ---check the thermocouple for carbon build up and in proper position or possible failing --last would be moisture in gas feed
Hi John...is there any reason that would make the boiler run too hot aside from the heat sensor not working? I have had a new heat sensor fitted, yet the problem still remained. Today I had a new PCB board installed and still the problem remains. The rads and water heat very quickly and normally the boiler would shut off until the heat went below the room stat..but it doesn't. Hopefully these description will assist in an answer
Sincere regards
Cassie
