Hello, I am experiencing problems with the above unit, lately no hot water even though the pipes are red hot nothing hot is coming out of the taps. The status light is flashing green.
It will fire up for a few seconds and then stop with the green light flashing again.
The central heating is not on just the hot water. There is another problem when the CH is on namely loud banging, gushing of water through the pipes, then quiet and normal function returns, this can happen a couple of days in a row or even go a week or so before the banging starts again.
The PCB was replaced by a Potterton engineer about 3 years ago.
Appreciate any help.
Thanks.
