Hello All,

I have have a gas halstead combi boiler 30/90.

My water pressure went down to 0.3 bar and my boiler stopped working. I
got the water pressure back to 1.5bar, but now it will not ignite or
even spark. It is not the air fan switch. Could this be the
thermocouple or a overheat stat switch? If so how can I check this or
is there anything else it could be?

Thanking you all in advance,

Malcolm

There is no thermocouple, it has electronic ignition

Yes, it's probably the OH cut out - which might be resettable

look in your manual

Is there a cutout switch on it, the resettable sort? It may be hidden
underneath if there is one. I had an old boiler about 6 years ago that had
just such a switch, I think it was a reversible metal diaphragm that went
*plink* if there was a problem and it needed a hard push on the diaphragm
button to reset it back to its original curvature. Of course, this may have
nothing to do with your problem!

The other thing to try is to 'reboot' your boiler by turning the electricity
off for a few seconds then turning it back on again.

I'm not familiar with the Halstead boiler, I take it it doesn't have a cut
down microprocessor in it like my Vaillant does? Certainly the first thing I
do if I have a problem is turn it off and on again, all the lockouts I've
had were cured by this.

Which is why with boilers, if you don't know, it's better not to guess

Turning it on and off would have caused some kind of damage or explosion
then? I think not. It is easy to do and eliminates one line of inquiry.

Hello Andy,

It was the reset switch under the boiler which I would never have
noticed. I was all ready to get the professionals out. Hot water at
last, thanking you greatly!
