Combi Boiler Lighting problem

m4rky

Hi, I have a problem with my Ariston EuroCombi boiler.
This morning the central heating was on and the other half managed to get a shower in but when it came to my turn the boiler stopped working.

On the control panel the ignition failure light was on.
So I pressed the button and the pilot light came on.
Then two seconds later the light went out again.
I tried a few more times but the pilot light went on and off again.

I left the boiler switched off for half an hour and tried again.
This time the light stayed on for at least 10 minutes and was still on when I left home.

I have an engineer booked to come out but the earliest he can get here is Wednesday!

Any body have any ideas what the problem could be.

Is it something I can do before the engineer get here.

Just a heads up on the issue would be great.

Thanks.

This is a fairly common problem.
I am no plumber but I believe the normal reason is a faulty thermocouple; a fairly easy job to replace.

Hmmm... Sounds expensive, well aren't all boiler repairs!!

Any idea of cost.

Thanks for the reply

Like most call-outs of tradesmen these days you are talking a £50 min charge.

If it is a thermocouple I would think in the region of £70 would be reasonable.

Cardew Thanks...

Is that £70 for the part or Fitted price.

I assume fitted as I have seen a few Thermocouples for other boilers on t'internet for £10-20.

I agreed thermocouple until I considered

This time the light stayed on for at least 10 minutes and was still on when I left home.


Its been quite a windy day and it might just have blown out a couple of times. If the thermocouple has gone the pilot light will only operate while you press the button to keep the gas valve open.

I guess the price of the job depends on where you are but I'd be disappointed to pay n more than £50 - every engineer worth his salt should have a replacement on the van. [ £5 in P&P on ebay]
