Recently had new PCB on the boiler as it was constantly needing resetting .The boiler now seems to work fine but the flue exhaust has become colourless ( previously white on cold nights) although hot air is being expelled .Is this a fault ? Our plumber could not explain it.
Am having problems with my Potterton Suprima 60L - no hot water for three days. Red light is flashing continuously. Tried to re-set it but nothing happened. Do you know what the problem is?

Thanks very much.Not sure if any pressure adjustments were made so I will get that checked when the boiler is serviced .

Its not a fault, just down to how much vapour is in the flue gases. Did the gas pressures get checked ad adjusted accordingly when the new board was fitted?
