The flashing SE error on my WM-11150FB was due to the motor casing not being earthed properly. Remove the rear cover and look on the motor casing for an earth cable. The one in my machine had broken away from the motor. I remade the end of the wire and screwed it back to the motor casing, machine working fine now. The hall sensor in the motor needs a very good earth to work properly.
