Baxi combi boiler model 80eco, intermittent fault on the PCB. Boiler sometimes fails to fire up when hot water tap opened or when heating set on timer. After checking the PCB I found that if I unscrew the cover and leave the PCB hanging down on it's hinges it works fine, but as soon as it is closed back up it starts to fail again. The only way to get it working then is to turn off the power and wait 10 minutes before switching back on, this works for about 30 minutes before failing again.
I have tried re-soldering all the joints on the PCB, but still the same. All electrical connections appear to be fine.
The problem started about a month ago but is getting worst.
Anyone come across this or similar, or anyone got any ideas.
We have been in touch with Baxi who want £300 to come out, and try to fix.
