Went to a look at a job as no heating and water. Leaking TRV had caused pressure drop so nice easy fix.
However the boiler pressure was 0. No fault codes but the pump was continuously running. display showed 'c' for heating mode and burner was off.
Fortunately the pump seems ok, and its back up and running, but I thought all combi boilers would lock out below 0.5 bar? or at least show a fault?
