Remove lower trim panel below door & also panel behind the trim. You will find an access opening. The flood sensor is near the front centre. It is a polystyrene float which operates a microswitch. Make sure all power is off before working in this area as some wires are live even when not running. If tray is wet, dry it and then run machine while you watch for any return of water. One cause of leaks on this machine is the rollers for the top basket which screw into the side walls. Make sure they are tight. If loose they will leak water through the screw hole.
