My Zanussi WJS1265W Washer drier has started to report fault code E10. I understand this is usually a water level pressure switch fault or blockage. The machine will go through its wash/spin cycles normally but stops and reports the E10 error when the program moves to the tumble dry cycle. The wash/spin cycle fills, runs, and empties as normal seemingly indicating that the pressure switch system is sensing the water level correctly.
Any help diagnosing where and what to test would be appreciated
