Hi having just installed one of these have fitted many the customer has said it has flashed up code 168 ,just wondering before i get in touch with the baxi tec guys does anyone know what it is, i know there are several hidden codes o these but aint seen that one before .

E168 =
Internal Bus Timeout!
PCB Internal Communication Conflicting (as per the tech bulletin)

Possible faults
Gas valve
Igniter or
Pump

But more than likely the PCB

e168 on a duo tec means pcb is doing a self diagnostic check.switch off at spur reset then leave it on e168 for 5 min and if after 5 min does not clear its self with out reset replace pcb

hiya was at warrington baxi few weeks ago.we fit bout twenty duo tecs a week and they sent me down there for a week problem solving on them.there head honcho gave this advice on this code.but he did freely admit most times it means pcd goosed

the most common breakdown with this boiler is when u service or install and people dont place the air pipe on the slim side of the pcb and allow it to kink when the pipe gets warm.nice easy one to watch out for comes up e133.

Hi,

Hope someone can help, I've got E168 but only when I use the central heating. The radiator light comes on but not the orange 'flame' light.

If I do a reset an use hot water the pipe light comes and as does the orange flame light and all seems well - then use the heating and we are E168 again.

I tried the 5min pcb reset thing and same problem....

any thoughts?

thanks
