baxi maxflow - No Heating

gadgetguy0 · 18 Apr 2011

Hi Guys

I have a baxi maxflow combi WM boiler. Today the heating would not come on although the hot water is working ok.

Initially I thought it was the remote towerstat (wireless thermostat) I removed this and connected its original digital one. But the boiler still won’t fire up. I then disconnected that and connected terminal 3 and 4 together taking the stat out of circuit, but it still won’t fire up.
The boiler is in the correct mode (water and heating selected) and central heating temperature control on the boiler is at about 75% so it should be on.

Any help would be appreciated.

Regards

Phil

I'd check the div valve motor, IIRC has a honeywell 3-port valve.
