Hello,
My boiler is on the blink for a while now and after searching the net got the feedback of the PCB's being the most common fault. How do I get at it and how does it come out? The model I have has the door on the front side to access the controls. That pulls off but I presume I have to take off the whole cover to gain access to board! Any suggestions would be great,thanks.

common fault with potterton suprima now updated pcb cheapest probably get british gas to fix they do a on demand fix that includes parts and labour pcb costs approx £150

If a registered Gas-Safe engineer can do it - anybody can...

Unless covered in conductive material - like carbon dust or moisture for instance - cleaning will achieve nothing.

You do not qualify or explain "on the blink". Go here nevertheless...

Intermittent connection faults on electronic circuits can sometimes be traced by tapping gently with a wooden spoon.

Boiler PCBs are subject to failing Electrolytic Capacitors - they tend to fail over time and particularly in a warm environment - and boilers are warm environments.

Good luck...
