Remove lower half of back panel. Dry off bottom tray. Run machine & watch inside for where the water comes from. Usual places of leaks on ECS is the short hose from bottom of plastic bowl to the drain pump. If water creeps out from behind or from under the drain pump then it will be the pump diaphragm seal. They used to be available as a spare part. If water drips down from bottom of bowl area & especially if the machine is very noisy when on fast spin, then the main tub seal & bearings will need to be changed.
