Boiler wont fire Potterton Profile 80e

DaveRob · 15 Feb 2008

This is the first time I have used this site but you seem to have been able to solve most things so I thought I'd try you with my problem.

I have a Potterton Profile 80e last night then heating was on and then just went off. The boiler was calling for heat for both CH and HW but wouldn't fire. Switched off and fired up again the plot lights but continues to spark at the pilot assembly. Does this mean the ignition/detection electrode detector is no longer sensing the flame and therefore prevening the main solenoid from opening to fire the boiler.

Assistance Appreciated

Sounds very much like flame rectification fault

is that the piece of metal in the flame with a wire going to the pcb.

I take it that it is more likely to be that than a fault within the pcb

It is the piece of "wire" within the flame, could also be the lead or the PCB

There the pilot burner, the ingnition and then a piece ot metal attached in the flame the wire from this then runs to the pcb

could be as simple as a partially blocked pilot
