Baxi 80he Flame Failure

[xabugax]

Hi guy's. I have an annoying problem which seems to be getting worse. Not sure what is causing it. Please can you point me in the right direction.

When the boiler is in the water only mode all is well. When its on the rads, it tries to fire and and goes to flame failure OR if i unplug the pressure sensor pipe from the gas valve we have heating! - but this then trips out after heating up and we have flame failure again. then it's a chore to reset. is the gas valve faulty?

Trap is not blocked, tempreture sensor was replace a coup0le of days ago by a fitter who thought he'd fixed the problem.

Any help would be appreciated.

It needs a service

It has been recently serviced and is a definate fault. The boiler itself is only a couple of years old. The flame failure light blinks.

I know what is wrong and as above

It needs servicing (correctly)

I second Baxpoti on this, from the symptoms described it is something that would be rectified if the gas safety checks forming part of a complete service are carried out.

Who serviced it and what instruments did he use?
