Intermittant fault in that it stops near end of cycle with excess detergent light flashing. Open door and clothes are sopping wet. Change to spin only and it works fine.
High level 140mm still detected, likely the pressure vessel is clogged or appliance is not getting rid of water in time, if for instance appliance went to spin before all water was out this would pressurise pressure vessel & pressure switch & F5 excess detergent fault code would be generated.
Take a look at the drainage manifold (running up inside at back) check for blockages.
