Zanussi ZKI245 resets mid wash?

Hello,
I have a Zanussi ZKI 245 Washer-Dryer and it sometimes resets mid wash. We program it to start and it gets halfway through the cycle then resets the timer. Usually it still has water in the drum. Usually when we start the wash again it finishes fine. We don't see any error codes on the machine. It seems to be getting slightly more frequent though.

Any advice is welcome
