Hi, we have a Ferroli F30 that hasn't been working for either CH or HW for a while.
The low water pressure light is flashing despite the pressure gauge reading 1 bar. Having spoken to Ferroli I 'overrode' the low water pressure sensor by just joining the leads to it with a piece of wire and it worked fine, so I changed the water pressure sensor itself but that hasn't solved the issue. If anyone has any suggestions as to what else I can do I'd be very appreciative! Could changing the pressure gauge itself fix it? It seems to work fine as it rises/falls as I fill/bleed the system. Someone has mentioned that the flow and return valves could be jammed but I'm not sure what this means?
Many thanks in advance
