Unless you jarred the machine it's the timer. You can check this by bypassing the lid switch and seeing if it will cycle.

Which tank is loosing water?
Number 1. Make sure all curtains inside are in place.Curtains help keep the water in the proper tank. For example, curtains are missing between prewash tank and wash tank, the wash tank water could be significantly splashing into prewash tank and out the p.w. tank overflow. Are you ruling out the drain because you replaced o-rings? Look at the floor drain as machine is running. Do you see a large flow of water going down drain? There is a drain heigth adjustment on the drain lift. Mabe the drain stopper is not dropping far enough.

your valve is not closing or your cycle isn't reading correctly. there should have been a diagnostic read process that should have came with the machine. if not you may have to end up buying a new drian assembly
