Main Multi Point FF playing up.

armyash · Jun 17, 2015

Hi guys

been sent to this property a few times

Their water heater keeps playing up, until today when ever i have been there it has been working fine. Today I got sent there and it would light for a few seconds then go off, relight then go off and so on. About 2 months ago we upgraded the gas pipe to 22mm and it had been fine.

Any experts here know what the problem could be? I'm thinking either a temp sensor is faulty or the gas valve needs adjusting

It was fine for 18 months then the problems started.

Thanks

Have you checked the water flow sensor?

Not today as I didn't have time, was sent there 5.50 just to check gas inlet but 3 weeks ago had it off and checked for blockages.

Is the pilot light going out Ash? If it is, it's the pilot injector. Undo the brass but in the centre, just inside the case. There's a brass injector in there, note which way up it is before you remove. Clean teeny weeny hole out with a strand of cable flex. Re assemble and gloat at your brilliance.
