Hi,
Could someone please help with the following; my boiler fires perfectly for central heating but I'm getting dry fire error for hot water. System is (I believe) an S plan with a Potterton promax SL 12. I have had a plumber tell me it was an electrical problem but have since had an electrician check all connections and everything is fine - motorised valve operates, pump runs, signal gets to boiler but it still doesn't fire.
Looking through the fault finding section of the boiler instructions for dry fire everything seems ok and it says next step is remove/replace flow switch, but surely this is working for central heating to work?
Any help gratefully received.
