Does it switch between HTG and HW ok?

Its still worth a shot anyway. If you take off the front casing, (the user casing with the dials) on the back of that, you will see a little potentiometer switch with 3 settings. Just double check what setting that is on please

There should be 2 screws either side and it will just fold down.

central heating adjustment is set 3/4
gas value pressure setting mode is set to normal op

Was thinking it could well be the board. I've had a few go like this and it was the PCB. Call an engineer out to have a look mate. Sorry I cant help much more and let us know the outcome. Cheers
