    Grant Vortex Combi - Overheat

    Boiler was removed from an NT property as they were upgrading to heat source pumps, supposedly it had done very little work. There is one valve above the magnetic filter, can't see another one.

    Grant Vortex Combi - Overheat

    UPDATE: This thing is still driving me mad, lost all pressure overnight, filled via loop, strangely the DHW pump was trying to pump while filling. Not 100% sure but I think turning on the cold tap in the kitchen makes the boiler cut out when on central heating, only done it a couple of times...

    Grant Vortex Combi - Overheat

    All rads are hot, dhw hot, rad above boiler is first, no trv as in airing cupboard with it just cracked open. Purged prv, opened all rads to max, fired it up, no air at all in the heating system now. Turned on dhw, can hear air circulating, not as bad as it was but still there, how do I purge that?

    Grant Vortex Combi - Overheat

    Turned back on to standby (switches in central position) after 30 minutes rest, pump working, hot water flowing, had some air pass through pump, bled rads and had a bit of air from one. Always seems to be a bit of air in the one right above the boiler. Fired it up again after pump had stopped...

    Grant Vortex Combi - Overheat

    Recently had a 2nd hand boiler fitted, unable to afford new as no income since March. Initially it all seemed to fire up and do what it is supposed to do, last week it went into overheat mode. Engineer had told me CH pump was in need of replacement, sure enough the overheat light was accompanied...

    Zanussi F 1245 W

    Picked up said machine from brick shed it had been stored in for 2 years, was working perfectly when stored. The Programmer/Timer does not click round and the thermostat does not cut out the heater even with a new thermostat fitted, could it be I have the wires on the wrong way round?
