Can anyone point to possible cause on hot water issue on a potterton 30he.
It is an occasional fault, when it happens the following occurs:
when hot water is drawn off, the fan kicks in but there is either no ignition attempt or the ignition is delayed by upto 2 mins? so you may just get cold water out or wait ages for hot water...
other times hotwater fires up straight away but then goes cold..or hot and cold. Hot water control knob is set at around 40 to 50c but the hot water can come out very hot?
When the fault occurs there is a red flashing light on the 50c indicator which is also located above a fan sign (but I think the fan is fine, like i said...fan can kick in but no ingition attempt)? as its only intermittent I would be glad to leave it (can of worms) but im sure you guys will have some good pointers!!
