pilot light not staying on

RyanandDonna · 7 Jul 2005

We have an old thorn Olympic gas boiler, and the pilot light will light with the grey button pressed, but once released, pilot light goes out

~ Replaced the thermocouple, still no joy

~ have recently turned both the water and electric supply off for other work, doubt if this has any effect, but that is why I am asking the experts

~ any ideas?

is the pilot flame on the thermocouple

is the flame big enough

if yes to above gas valve (CORGI)

RyanandDonna · 7 Jul 2005

Yes to both ~ thanks for a quick response!

Does the

mean I need a Corgi, or does it mean I can have a go myself ~ also, any idea how much ~ are we talking < £100?

kevplumb · 7 Jul 2005

yes you need a corgi and dont ask (rules)

what model olympic

Not sure ~ looks like a big white one to me ~ looks old, guessing 12 years as thats the age of the house. Numbers on it say ~ V4600A 1023 2 DIN-DVGW 75.02c 050 if this helps

30/50/b dia

should say 20/35 cf, or b, or fan assisted.

38/50 cf, or b, or fan assisted.

GCnumbers are, 41-789-42, 41-789-21, 41-789-65, 41-789-43, 41-789-20 and 41-789-66

No other numbers on it, just some CAT III Pmax 50 220 / 240V 50Hz 0.02 Temp 0 - 70C

Sorry ~ I have taken cover off and looked all over.

look at the label in the brown bottom bit that slides off

RyanandDonna · 7 Jul 2005

good news I found the label, bad news is the data is no longer visible ~ looks like some bonehead has decided to paint over the bloomin thing

Ok try this.

Turn the knob in the direction of the arrow and wait for it to click about (3mins) then try to light it.

Fault could be insufficient pilot or failed magnet in the gas valve, both a corgy job

RyanandDonna · 7 Jul 2005

I have tried this earlier, but no joy ~ will try again tomorrow as the wifes asleep. Thanks for all your help so far!

Still no joy, I guess I need a Corgi
