this boiler seems to have an intermittent problem with heating/hot water.
When switched on it will work for a while and then cut out.
When the boiler cuts out there is a flashing light which according to the manual denotes air pressure switch failure. I have replaced this part, still same problem.

You have to play with the boiler to get it to turn on(as in kick in heating or hot water) if it doesn't first time round ( switch it on and off, switch it to summer back to winter etc etc)

i have checked the electrical fan seems ok for voltage and resistance.

are we looking at pcb issues?

Any ideas anybody, thanks.
