My radiators and hot water keep going cold whilst the Combi is still running in the background. I keep having to re-ignite the flame to get some heat, then it repeats the above after 30-45mins. This has been happening now on and off for several months. Any ideas whats wrong would be much appreciated.

I have a Biasi Combi Boiler M90E.245 where the boiler switches itself off. When switched off you have to re-set the boiler to work by turning it off and on. It works for a short while, an hour or two, and then switches itself off. When working, the hot water and central heating works well.

I'm having similar problems. My Biasi boiler locks out & have just had a new PCB fitted. On resetting it locks itself out again after a minute.

I presume that you mean it goes to flame lockout and you reset it with the red button in the centre of the control panel.

This is probably a gas valve setup problem or a faulty ignition PCB.

However, either will need a competent boiler engineer.

You could call Biasi and ask for their local service engineer. Their number is 0121 506 1340
