Hello All

Does anybody have any ideas why the pilot light on my profile 50e
never goes out - even if I switch off the electric?

My guess is the pilot gas valve is either sticking or worn out. The
boiler fires up as normal, with both solenoids click and clunking.
There are no ignition clicks though - but I guess thats because the
pilot flame has already been detected.

Is there anything I can do to fix the problem? I'm pretty capable and
have fixed other parts of the boiler but I don't want to have to mess
with the gas supply for obvious reasons!

Thanks
Clive

its normal !

if you turn the gas off and let the thermo-valve cool down and switch the
gas on the pilot ligh will need to be re-lit

Is it **** normal, don't talk ********

The gas valve is letting by for some reason and needs replacing

If the volts are removed from the pilot valve solenoid, it should close
and no gas should pass through

on my potterton the boiler can stay unplugged and the pilot lght stays on -
there is a thermo based valve wich lets gas through for the pilot light -
this is the third central heating boiler (in 3/4 houses) that works this way
the other had an on demand piezo ignition, if the gas supply is cut the
valve closes and you have to do the 'turn knob ignite woth piezo and hold
for 30 seconds to ensure the pilot valve stays open - I can probably find
the diagram from the GCSE physics book which sjows the general principle

btw its sometinmes called the thermocoupler (not thermocouple) or pilot
latch assembly - like here

Yes, but your antiquated POS is not a Profile, is it ?

The profile has electronic ignition, it goes through an ignition
sequence and the pilot valve is only operated once the air pressure
switch has established that the fan is generating a sufficient pressure
differential, and the pcb senses that pilot flame before operating the
main gas solenoid

what you wrote was wrong and potentially dangerous information

now that clear and lucid explanation wasn't too difficult was it - why did
we have all the f**k off , b*ll*cks when that would have done nicely ??

It might come as a surprise to you that Potterton make and have made a
large range of boilers. Most of which have not used permanent pilot lights
and themoelectric valves for the last 15 years.

Looks like it must be a sticking gas valve.
Turn off the gas and get the gas valve replaced.

I'm surprised it will go through the ignition sequence.
I thought most boilers checked there was no pilot flame
sense electrode conduction before starting the ignition
sequence, to ensure the ignition sense electrode is not
shorted out by dirt rather than sensing ignition. Maybe
the Profile is too old for that check.

And, if anyone should know the answer to that one, its me isn't it

I have a feeling you're right, I'll check tomorrow
