Is it a combined boiler?
sorry ,meant combined boiler
Combi ,sorry can't turn off auto spell
Ok. If you run the hot tap ,does it do the same ?
Hi . you have a problem with either your air pressure switch or fan . when the fan runs the fan pressure, closes the air pressure switch to open the gas valve and fire boiler . this is a safety to ensure the boiler will not run if the fan is faulty . these can be tested with a multi Meter ,but I would replace the fan and air pressure switch .
Fan can be pricey unless you live near hanger lane in London and don't mind reconditioned. Around 140. Air pressure switch about 30.might be worth changing this first.
Oh , love Wales. All the best , would you mind rating me ,thanks
Try googling reconditioned boiler parts in Wales.not everyone will use them but it a lot cheaper and I never had a problem with them . by the way you can rate me but still stay with me for any other help you need
