I have read very helpful advice on how to do this but can't find the damn button to press! The picture in my manual looks nothing like the boiler. It shows a white knob whereas the advice says 2 black prongs with a red knob between them??? Staring at the inner workings of my boiler hoping the button will magically appear is not working! Slowly going insane and freezing!

Thankyou so much for responding Ian. Have to raid overdraft!

Update - Rang Glow worm at 60p per minute. They say I can't press this button myself as it's in the inner workings of the boiler - no wonder I've spent 3 fruitless hours trying to find it!

depeding on age of boiler it may be inside the combustion chamber on the right hand side. it will be on a small round black thermostat which will have 2 wires coming off of it and a small red button in the centre of it. this should be done by a qualified engineer as you need to disturb the combustion seal, and you should have them investiagte the cause of the overheating.
