She either disconnected the drain pump wires or reassembled it with something in the way of the drain pump..check for 120v at drain pump when pressing cancel drain button.......also check the drain connection and vacuum the drain hose out at the sink to make sure your line is clear............more then likely she reassembled it wrong and something got blocked in it.........go to sears parts website and put your full model number in and you can see a schematic of the breakdown of your sump motor and how to reassemble it....good luck

Sounds like maybe a bad timer/bad timer connection........check take the front panel off and inspect the timer connection and clean it very well and check for loose wiring............jiggle the wires while testing the different modes see if you see any sparks or loose wires..........
