Hi I'm new on here so please be kind :-) I'm having problems with my Baxi due tec 33HE combi it was running fine up till April but now the cold weather has kicked in I tried to put the heating back on it tries to switch on but the heating wont come on the rad light comes on and the fan kicks in but it seems like the ignition wont kick in, the hot water is fine when the hot water tap is turned on the flame light comes on but when I switch the heating on an error msg EI68 flashes. I was a bit lazy last year after draining the system (moving rads) I didn't re add the inhibitor so I'm wondering if any of the valves could have jammed with the crap?
