worcester 24i not lighting

[stanna]

Hello

Got a worcester 24i combi. Its been playing up for a day or 2. heating on but boiler goes out after 30 mins or so. Only way to relight has been to turn off heating and turn tap on. Boiler then lights and stays on for a bit. When off it constantly tries to relight re ignition but nothing happens.

Today i turned it on it lit. Went out came home it was off. Tried to light. nothing happened. Fan is running. Tried hotwater makes all right noises but does not light and has stopped sparking. Went upstairs with heating left in on position and heard a bang. Mrs said it lit for a moment then whoomp. Still not working.

Any ideas much appreaciated.

Thanks
Stanna

It sounds to me as if there may be a problem with the gas combustion aspects and that would required a competent CORGI engineer.

Presumably you have never had it serviced and that may have a bearing on the problem.
