Potterton Suprima 50 HE Boiler problem

Hi, I have a Potterton Suprima HE 50 boiler that was working fine until Saturday. The boiler will fire up as normal for a few moments but then go on to lockdown. According to the fault board indicator (the lockdown light is the only one alight and is flashing) that this is an air pressure signal fault. Any ideas what the problem may be and what is needed to fix this? Many thanks Jaime

Don't know about the 50 HE but my Suprima cct. board failed after a service visit.

Check the solder joints with a magnifying glass where the mains connector is mounted. In my case, flow solder bath techniques did not provide enough time/heat to make sound joints.

1st. service job is to unplug the connector!

I too have a Suprima question.

Apparently the "green" light sometimes comes on, boiler does not start up, and only works again when the green light is pushed. Of course, it behaved perfectly when I was there. (And it is a two-hour drive away.) Is this a symptom of the PCB issues that others have been going on about? Or have I got wrong end of stick?

Pcb or module?

You mean the reset button? Pushing the LED won't achieve an awful lot

Probably, but not really possible to say anything for definite

As Ed Sirett (ex of this parish) once said, its the only boiler where he changes the pcb then looks to see what else might be wrong

Flex the circuit board? ;-) Which in a Suprima, might even work...
