many thanks for your help.
The guy has been, hes checked it and reserviced it and appart from one thing its in fine working order. Its a vaillant 242E, which I have to say, on the whole has been brilliant.
It had a diverter valve fitted about 3 years ago. The timer died a bit before that...
Hi,
I have a vaillant turbomax combi. The pilot light is refusing to turn on (there is a clicking sound but the pilot light indicator stays dark). The error pilot light indicator doesn't show this.
I've turned the boiler on and off a few times, sometimes the pilot light indicator flickers...
