Hi.

I have a fault with this boiler. No hot water or heating. Error code, (after pressing the appropriate button), is S F6. Unfortunately cannot find the installation manual so cannot find out meaning of code and no joy on net.

When I reset I hear the boiler 'starting' but nothing after that.

When I turn the heating knob up there is no response at all.

When I turn the hot water on the boiler 'starts' but no heat. I notice that the pump does not circulate when I do this.

Gas is OK. All water connections fine. Ditto electrics as far as I ca tell.

I suspect the pump. Am I right in thinking the system won't fire up if the pump is faulty.

Otherwise I can only assume a problem with the ignition.

Thanks for any help.

Mike
