No hot water / Heating
I think I may have a couple of faults....Firstly, I noticed that the temperature of the hot water was gradually decreasing over a couple of days. I checked the operational controls and when I called for heating, the pump kicked in but the temperature of the store was low so it was just pumping cold water round the system. However, when I ran the tap, there was no recognition for demand on the pcb and no voltage to the dhw pump. However, a day later, the pcb would recognise dhw demand and the dhw pump would kick in but now it won't recognise dhw tap being opened at all. This tells me I have a flow sensor issue but not sure which sensor needs replacing. Also, I assume that I have another fault as the temperature of the store is around 20 degrees and I am not getting any voltage to the flow boiler. I have checked the flow boiler and both overheat stats and they are giving correct readings. When I was investigating, I saw that the mains supply plug connector on the off peak pcb was loose and just pulled away from the board. I have since re-soldered this to the board and seem to have good contact. Any help would be greatly appreciated

Board could be gone after reading your post.
Check the fault codes.
And the function display on the board.
