for all of you who have this problem a fix (so far!) I have now taken out and tipped on its side and drained all the water in the pipe, also whilst the machine is on its back remove the bottom cover 4 screws and undo the 2 screws on the floor and lift off cover, you will see a black float swich, ( flood alert FA fault) this can stick and is worth checking operaton. if all ok refit and put back. if the fault ever occurs again you now know where this is and can try tapping the bottom panel to reset, this worked for me when I put everything back to reset the switch. if This fails again I have found online you can get a new switch for approx £36 and this will be my next step. Good luck. PS what a great site this saved me loads in call out fees etc.
