I have checked my combi boiler today and it's flashing A1, can anyone help out with that please? Meanwhile I'm waiting for the seller of the house to get back to me.
The pressure is 1.1, but nothing happens when I turn the knobs, think I will have to consult the guy who sold me the house as he had it fitted and I'm the only one who has used it.
Hi, any help would be greatly appreciated. I have moved to a new flat fitted with one of these boilers, it's brand new and I have been trying to work out how it works for 3 weeks! In frustration I have turned it off and I'm now having trouble turning it back on again. I'm cold have no hot water...
