So it's been a couple of interesting days in the warmth of my world... My fiancee managed to break the connector of the hot water to one of our power showers on sunday morning. We only found out when water started pouring through the kitchen ceiling, so after rushing round turning off all sorts of stopcocks and all the switches for anything water related, we rumbled the problem, isolated it, and turned everything back on.

Last night, we noticed the heating wasn't on, so checked the combi boiler, we have a pilot light, and the programmer (ep2001) was working (although I've since reset it to make sure, and still no joy). But still no 'wumph' of things getting warm.

We do have some hot water, but that's from the immersion element, nothing to do with the boiler.

Any hints, tips or suggestions? I'm going to call an engineer out for tomorrow, but if anyone here can help, I'd be grateful!

Cheers

Have you checked that the system is up to the rite presure about one and ahalf bar

Your boiler is not a "combi" neither is it a modern style condensing boiler. Combination boilers do not have hot water tanks with immersion heaters in them which is one of the major drawbacks of combis...lucky there...

If the Fan runs and the pilot lights the fault is likely to be...

Pilot flame too feeble to send sufficient signal to control board to open main gas valve

Control PCB sensing pilot flame OK but not acting on it by opening main gas valve

Control PCB trying to open main gas valve but gas valve defective.

When the engineer comes ask him nicely to diagnose the fault and repar it and not to guess what might be wrong - some of them do this at the householder's expense. The first place he should look is at the control voltage that opens the main gas valve - if that is present it's likely to cost around £250 (guessing) for fitting a new valve. If the engineer is from British Gas he will declare the boiler obsolete and insist on fitting a new one and a power flush of the radiators £2500 or so.

Good luck...
