Pilot light fault Glowworm Swiftflow 100

[Russ02]

Hello, can anybody please help, -5c here, typical of boilers.

For the past week the boiler has been going out, I relit it ok. Last night it would not re-light. I had bought a spare thermocouple so fitted that this morning.
Same problem, I press the bypass & ignitor, it lights up fine, as soon as I try to turn the bypass knob onto normal pilot, the flame goes out.

Is it possible the new thermocouple is faulty? Or could it be something else?

Thanks for any answers

Russ


Problem solved thanks

You will get no answers here im afraid, could of suggested things to check before you messed with the gas side of things

Ok problem sorted, my chum who used to work on council c/h sorted it. Problem was the cutout switch that connect to the bottom of the thermocouple.

I only swapped the thermocouple, wouldn't dream of touching the gas side.

Regards

Thermocouple is part of gas work side area, it is there in case the flame went out, it automatically shut off the gas flow safety.

Never thought of it as the gas side, many DIY stores sell thermocouples.

Checked past threads on this forum, didn't seem to be an issue.

Really looking like time to start saving for a new boiler, this one being 22 years old. To be fair it hasn't given much bother over all those years, 2 thermocouples & an electrical connection that Baz identified.

How much ££££'s is a fair price for a fitted similar power boiler to heat a 1950's large'ish 3 bed semi on top of a hill & very exposed to the elements.
Which make of boiler is the most reliable? my chum reckons Worcester, is that the general consensus among c/h Engineers?

I charge £740 to fit a heat only boiler and £840 to fit a combi and think those are reasonable prices.

Thanks for the reply Tony,

I haven't been able to price a boiler yet, not sure which model I'd need. Anybody know off top of head price of a Worcester big enough for the description given above?

Most better combi boilers are about £800 to £1200 to buy.

Some installers charge a lower labour charge and add a markup to the boiler price so its the total price that's relevant to you.

You will not save anything by buying the boiler yourself if that's what you were thinking.

Few engineers here much like Worcesters here.

Intergas, Viessmann and Vaillant will be the most popular.

Thanks Tony,
No, I wasn't thinking of buying the boiler myself, just specifying which boiler I wanted so I don't get something unreliable.
O f those 3 you mention, which is your preference? I've only heard of Vaillant.

I suggest what I think best for the customer in each case.

Some others choose what is best for THEM.
