BAXI WM38 / 3RS boiler problem

[nation73]

Hi all
I have the above boiler in my property and the burner will not start
The pilot light is on
The green switch is not stuck
The front room thermostat does change something on the boiler (can hear noise difference!)
I have a 40 weeks pregnant due today partner and the above isn`t helping!

Could anybody please try to point me in the right direction!

Any help would be much appreciated and for info upon my investigation the thermocouple as it enters near to where the pilot light is seems to be slightly cracked at the entry point...

Excuse my ignorance or stupidity but could it be that at fault?!?!

With everthying "ON", try turning the boiler thermostat up and down. Do you hear a click?

Hi - there is a click which happens halfway between `off` and `1`

Yea, unfortunately, it sounds like the gas valve. Make sure the green or grey button has fully popped out. Is it green or grey?

It is a green switch, it seems to me as though it comes out fully but I can get hold if it and pull it towards me say with 3-4mm play on it, should it be solid at this point as in being pushed out?!

Sounds like the valve IS sticking. Try pushing and pulling a few time, but when the green button sticks, it is normaly easily pulled forward.

I don't normally give gas advice, but this is your final shot, and a long one at that!. If you can lift the OUTER case off the boiler, turn'stat ON, and after it clicks, use a hammer to gently tap the underside (as you view it). You might get lucky, but even if you do, it is likely to be temporary.

Beyond that, I'm afraid, it is a case of finding an RGI.
