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?

No Tim -

The HE is completely different

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

Well she said she pressed the green light - but I suspect that it is the
reset button really. Her eyes are somewhat challenged.

I'll email.

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

Shredder's more the mark

Flexing a suprima pcb ?

how many pads do you think you can break away from the tracks in one go
?
