Powermax 155x

[Marky66]

I have a Powermax 155x.On Thursday we noticed the Central Heating had gone off even though it was still on the timer.The Mains light is on and we have hot water, but it doesn't appear to ignite and the lockout light has not come on.Any ideas?

Marky, Check that your other controls are "calling for heat", i.e. ensure the room thermostat has not been turned down, and ensure the boiler central heating control has not been turned down / off. Other than that I suggest you contact a CORGI registered heating engineer.

Thanks Pilotlight.The thermostat has never been less than on 10.I put it up to 30 ealier today, whilst the heating engineer was here but it didn't do anything and he wasn't sure what the problem was as everything looked fine.He told me to ring on tuesday when he will have discussed it with colleagues.

ok Marky66 you have a boiler thermostat inside the boiler which can be accessed by lifting the small panel at the top of the boiler straight up. make sure the power is off as you'll have 240v wiring center exposed., Its a small pin like control with no handle, make sure that this has been turned fully anti clockwise! Also you'll see a small red button on the right hand side of this boiler, just to the left of the fan, press it to see if the boiler has locked out here. If you are getting hot water the problem should not be expensive as the major componants are working fine. good luck.

Thanks Lembo.After calling out 2 Corgi installers and explaining to both that we seemed to have had max heat on 10 on the thermostat, we finally went for Brit gas Homecare who identified that the thermostat was wired incorrectly.There was no "click" beforehand.
