I have a BAXI Solo boiler. Today it failed to start up. No Fault indication initially but after bleeding the pump (to no avail ~ no water bleeding out) the fault indicator shows "no water flow or reverse flow". It appears there is no water feed to the boiler. The header tank is full with no restriction at the outlet. Opening the drain at the boiler inlet produced about 2 litres of inhibited water ~ I suspect this came from the outlet side of the boiler. I am now about to lift the flooring in the loft (bungalow) to investigate further. The pump is reasonably new and runs okay. (not seized).
Any ideas and suggestions will be gratefully received. Thanks
