Domestic Hot water keeps locking out after 10 minutes.
Checked all thermo's, cleaned the DHW and still nothing. The wierd thing is that the Central Heating works fine.
Have you checked gas settings on how water, venturi on fan clean? you say 'cleaned dhw' is that the plate heat exchanger? for the sake of a couple of pound you could replace ntc's. Also does it lock-out on overheat?
