Thorn Apollo relight problems

[Pacman]

Finally sorted my Thorn Apollo out and had it gas safety checked by a good Corgi guy round the corner, he found the gas pressure wound up far too much beyond the boiler's limits , of which he turned down .

But I have an intermittent problem which doesn't seem to happen when he is there.

The Boiler makes a loud clack then blows itself out once hot (hot enough not to need any more through the HW & CH) the has to cool right down before it will relight, of course I cannot replicate this when he is here

No problem I just relight it, but tonight I tried and it lit as normal then when I let go of the gas valve it went out so I tried again and when I struck the igniter it went bang and flames shot out the flue

Pretty scary the boiler off and I am calling the guy back in the morning but what could this be?????????????

fsd failure on the gas valve I guess.

 

[Pacman]

FSD???

 

[Pacman]

So the gas valve is knackered the engineer is going to see if he can source another, so I don't get fobbed off about it being obsolete where is the best place to source a gas valve ?

 

[Pacman]

New Gas Valve quoted £260 fitted being done tomorrow night.

This is alot of money if it doesn't work, what else would cause or be attributal to so I can chat it over with the engineer before the boiler becomes beyond economical repair

 

[ollski]

Why would you be paying him for something which doesn't work?. If you have full gas coming through the valve when the pilot has gone out then the valve is shot. FSD = flame supervision device on the gas valve, it senses that the pilot flame is lit before allowing the main gas valve to open.

Far doos Ollski looks like its the right course of action for the moment, its just difficult to decide when enoughs enough and time for a new boiler and at the moment the £260 I haven't got let alone £1500 for a new boiler

The Apollo is a relativley simple set up what's going to happen to the modern ones in ten / twenty years when parts become obselete??

You replace 'em chief. Manufacturers reckon on a lifespan of 10 - 15 years before replacement. There is not much these days with sort of working life including most household appliances, cars etc.

hi,

i've got an old thorn emi apollo boiler in my flat...no idea what model it is as there doesnt seem to be any info on it...

the pilot light keeps going out - had a guy come a look at it who thought it was the thermocouple...he bought a universal one with him which obviously wouldn't fit because of the interrupter.

anyway does anyone know a good corgi guy in london (nw2 is where i am) who can change this and check the stats etc. so i dont have any more problems? the guy who came out seemed pretty clueless and isn't corgi registered so i don't want to risk him doing anything to the boiler...

any help much appreciated!
