Vokera mynute 35e fault code 07? Help!

BillBungler · 3 Dec 2008

My four year old boiler trips out and requires reset about once a day. the code flashing is 07 and manual says "call engineer" . I assume it is just a sensor which will cost not a lot. Just been made redundant so not keen to pay the quoted £170.00!!!

Any suggestions very welcome.

Thanks

F 07 should point to the thermistor needing to be replaced, according to the MI's.

07 is the thermistor.

top right side of heat exchanger, drain the boiler and remove with a long 13mm socket, new one in with new washer, refill, test, robert is your mothers brother.

wiring loom or pcb then.

just wondering if we have the right thermistor...........

The one I replaced screwed into the heat exchanger externally as you said with the 13mm socket.

Someone has suggested that there is a PRIMARY thermistor inside the combustion chamber above the burner which would trigger that fault code??

what do you reckon??

Thanks as ever

yes, you changed the wrong one and i just realised my quick guide to chnging it could apply to both thermistors as they are both at the top right side of the relevant h/e.
