my baxi 105he will not fire up at all. the 30 degree / flame light just keeps flashing 24/7 therefore no heat or hot water.
why is this please help me.
Condesate overflow is likely to be blocked / frozen as it leaves the outside wall of your property...so use boiling water or hairdryer to defrost Top of Condensate Weir may also be damp, affecting electrical terminals, so dry area out with tissue & hairdryer and then try to reset.
