My aging Wicks 40 Boiler has stopped working
It started rumbling, then it cut out the flame
I think its overheating, so now when hot, the pilot will not light
And when I di get it lit, and start the boiler after its warmed up
the boiler cuts the flame (saftey feature I guess)

Am I right in thinking the probe thingy stick in the side on a coiled copper
looking wire/pipe
has failed and needs replacing? is this called the thermostat or
thermocouple?

Can anyone tell me the real make of my boiler? its says Wicks 40 and thats
it.
Just a boiler stick on the wall, flames below a tank with exhaust tot he
outside and a large square
plate out side on the wall. OR where can I look for model number info on the
boiler?

Plus, anyone know a place I can get the part today? Portsmouth area UK
Thanks in advance

The thermocouple to which you refer is a flame failure device designed
to turn off the gas in the event
of the pilot failing to light or remain alight.

If the boiler is overheating, the reason for that needs to be investigated.

The thermostat turns off the main burner when the water is hot enough,
but shouldn't turn off the pilot.

It would be safer (and legal) to call in a heating engineer to fix it.

ok so the probe is connected to the thermostat
so what is causing the boiler to overheat if the thermostat is working
correctly?
this makes no sense

It can make a great deal of sense.

For example:

- The pump may be broken or on its way out

- There could be a partial blockage in the heat exchanger or elsewhere
in the system.

If the temperature rises quickly enough, the overheat sensing can trip.

However - back to the original point of it cutting off the pilot.

Either way, if the OP is not sure about what he is doing, he should
seek the help of a professional.

The problem may only be the thermostat, but other things should be
checked as well.

Sound advice. The boiler may have a thermocouple which is linked to the
overheat stat, hence when it overheats it cuts the pilot. The overheat
stat may have gone sensitive but is an important safety device. Are
there Trv's on all of the radiators so when the rooms are warm there is
no where for the heat to go? Is the pump failing and cannot get the
heat away from the boiler. A temporaray fix may be to turn the boiler
stat down so that the water temp is reduced and hopefully will not trip
the overheat stat. It may just keep you going until you can get an
engineer in.

thanks for the advice
The rest of the system, pump, valve, tank etc are all new
so its the boiler IMLO
The massive rumble when the boiler is hot, leads me to think its boiling the
water
but, llike you say, if the pumps working, the water should'nt stay in the
boiler long enough
for it to behave like that
No TVR's on the rads, but its been flushed 3 times this year so blockage
maybe not - no black sludge or anything
Thermostat ordered for next day delivery and Gas engineer coming tomorrow
when I ring him to let him know the parts arrived.
I might try lowering the dial on the thermostat to see if it behaves today
as suggested.
thanks again

If it's the Halstead Wickes boiler I think it is, then it has a sequence
board (600503?) - so no thermocouple

Sounds like it's a circulation problem

OP - is your pump working?

I thought he was referring to a thermometer phile.

Yes, you're right, my mistake.

However, it looks like Geoff's explained it.
