Baxi Bermuda 551

[Sutters]

I have a Baxi Bermuda 551 back boiler which recently made 'arcing'
sounds while opening the valve to fire up the burners. After a while
it stopped firing up at all.

I checked the wiring, and found 1 loose (loose-ish ??) wire in the
connector in the boiler. However it still doesn't work.

As a final test I by-passed the internal thermostat unit, but the
value doesn't open and the burners don't fire up.

I am hoping that someone out there has some helpful ideas.

Thanks,

Sutters.

I presume that the pilot lights and stays alight ok - indicating that the
thermocouple and flame failure device are ok?

If so, it sounds as if the solenoid in the main gas valve has died - unless
there are extra interlocks than I had on my 1960's version! Do you have an
installation manual? If so, it should have a spare parts list. [There's a
searchable database on the Baxi site at http://www.partsarena.com/baxi/ but
it doesn't seem to include the boiler part of the 551 - but it does deal
with compatible gas fires.]

Hopefully you can still get spares. You can get gas valves for some Baxi
boilers - and just the solenoid in some cases - from
http://www.pricerightheating.com/ - but you need the part number to be able
to identify the right bit.

UPDATE:
You appear to be able to get spares for a 551 from
http://www.mjtcontrols.co.uk/Applia...ture_ID=11&Appliance_Type=Back+Boiler+&+Fires
(watch the wrap!) - including a gas valve with a new part number which
supercedes the original one.

If that's no good, there are lots more links if you do a Google search on
"Baxi boiler spares".
