My boiler (Vaillant VC GB 242 EH) has suddenly decided to stop working (waits until it's getting colder of course).
When the hot water / heating is demanded, the pump and flue fan run, and the ignition starts sparking, but it just won't light. It doesn't give up either (like it did one time when the pump had failed). The ignition just keeps tick, tick, ticking until I turn it off.
I tried loads of places in the yellow pages, but they are all apparently too busy - even the ones that claim "engineer in one hour", so I was wondering if there is anything obvious I should check while I wait for them to run out of other work...
Also, if anyone knows of a site where I could download the manual that would be handy - I can't find mine anymore. It must have sat next to the boiler for at least 3 years - now I need the damn thing it's not there :-(
