installed one this morning and after filling it showed e10
it then cleared itself and tested through ok
looked on the faults but they only go up to 9 🙁
is it a fault or was it just a bit of damp and now all will be ok 🙂
Fitted one a week ago and E10 is coming up occasionally, going back to it on Monday so I will check connections on boards, will update you on outcome 🙂
Had one this week with a permanent E10. Replacing the inverter solved the problem. Access from the bottom, two plugs, three screws and one cable tie. Quick easy job.
