Baxi Solo 2 Boiler

[ladygolflover]

My Baxi boiler has "gone out". There are no lights lit and there seems to be no pilot light lit. The boiler therefore is not firing up the heating system when I turn the Honeywell thermostat up.

My hot water is still hot. The appropriate lights on the timer in the airing cupboard are lit saying that the system is on. It's Friday night of course and I can't find a plumber.

Any ideas anyone?

Thanks

try turning the power off to the boiler or the boiler stat to off for 5 mins
is it the rs or pf version

 

[ladygolflover]

Thanks for your time.
It's the PF versin, whatever that means! I've turned the electricity supply off. I'll see what happens.

 

[ladygolflover]

No difference unfortunately.

Hadn't realised how cold it was until my heating packs up LOL.

check that the hot water side of the system is firing up the boiler, if not check the fuse(s) if it does fire for water but not heating then suspect the motorized valve. The pf stands for powered flue as in it has a fan.

pf stands for power flue (has a fan). if there are no lights on the boiler but the programmer is ok i would suggest the fuse is ok, I would expect that the problem lies with the diverter valve or zone valves on your system as these are what will control the boilers operation.

gstens baxi - are you a plumber? Bucks is not that far from me. Do you do house calls LOL

 

[ollski]

There is a fair chance we may be able to give you a very good idea on the fault, but it really would help if you give us a response on the suggestions we give you

 

[ladygolflover]

Sorry Ollski - I appreciate your efforts.

Nothing is firing up the boiler now. Checked the fuse and that is fine. Turned off the electricity for 5 minutes as suggested. Nothing.

Usually the thermostat "clicks" in when turned up but that is dead also.

Did notice that when I turned off and on the power at the wall there was a slight clicking sound in the boiler which suggests to me that power is getting to the boiler from the mains but perhaps something inside the boiler is not firing for some reason.

 

[ollski]

Ah right ok, if power is getting in to the boiler to make it click but no lights are on it would tend to point towards the board.

Sniff it ! The last couple I changed had melted some plastic!

Air pressure switches on solo2 pf is very prone to sticking in the on position after demand for heat has gone ,thus stoppin the fan starting up again when there is a demand for heat again

 

[ladygolflover]

Thank you all for your help. Managed to get a heating engineer to call today. He said it was the thermostat. Fitted a new one. Now have heat. Ah lovely. Warmer but poorer

 

[ollski]

thats exactly where the fault finding chart leads you aswell....textbook

 

[namsag]

Olski if that is exactly where the fault finding chart leads you (text book) how come you came to that conclusion when you had said sounds like the board in your previous answer
