Evening,
Looking for some help & advice please. I've read similar problems in other threads, so bear with me.
The boiler is locking-out in overheat. Its pretty irregular and so far my local engineer has checked or replaced the thermostats, thermistor, changed the door seal and checked wiring etc. Pump has also been checked and is fine.
Its already cost me a few £'s, however engineer is now suggesting changing the PCB - not cheap and no guarantee. Incidentally, Baxi technical department advised the engineer to double up the door seal, which he's also done?
I'm now considering biting the bullet and getting Baxi out, or getting rid of the boiler altogether! Its around 9 years old and otherwise looks in good condition, and runs well until it locks out!
The overheating lockout only happens when the heating and hot water are asking for heat at the same time. If theyre on separately, it doesn't lockout.
The boiler will fire up ok and runs for 20 minutes or so before going into lockout, again only if hot water and central heating are on at same time. Also, after resetting the boiler, it seems to run fine after that.
I was wondering if both hot water and heating on at same time = increased heat, or something that's affecting the thermostats?
I'm loathe to pay > £250 for a PCB if it doesn't fix it!
Therefore if anyone who has experience with this boiler could advise I'd appreciate some help, or advice. And i hope I've described everything properly...
Thanks
