Back in June 08 paid £170 to get the diverter valve diaphragm replaced as had corroded and pcb also as had no running hot water but radiators worked. Now as of last night have no gas flame and won't light even though boiler sounds like its running electrically. Ice cold water, no radiators, no heat! So stressed out and cold and wondering if I need a new boiler if its just going to break all the time? Is from about 2000 I think but no instructions! I know its an auto light boiler but has anyone experienced this and how much was it to fix? Will get a corgi gas guy out tomorrow.
