I have a really weird problem with the above boiler.
When you select either hot water only or with central heating, and turn a hot tap on, the boiler will fire up as normal for a minute or two, then suddenly shut off.
If you then turn the hot water tap off the boiler will randomly come on of its own free will even when the heating is selected off and switched off, and the room stat is turned right down.
With the heating selected on you can get the boiler to come on and off with the roomstat, sometimes by going below the room temperature and sometimes by going above it, but again this seems to be entirely random.
I have gone through the troubleshooting in the manual, and it seems to point to the fan, but this does'nt make sense because if it was the fan then surely the boiler would'nt come on and run of its own free will.
I'd appreciate any ideas,
thanks
