Hi Mick,
I think our 1265 W is doing the same thing - keeps stopping mid cycle and lights go out. You have to hit the start button agin which normally prompts it to start going again but when coaxed along, it does normally finish the wash & dry. Just can't rely on it finishing while you leave it alone. Also sometimes get an E90 error. Did you manage to determine the error in the end as we are also having to consider replacing due to the cost of getting fixed?
