you may have a water valve problem in dishwasher . but first shut off power to d/w at breaker. remove bottom cover, you might need torque screwdriver to remove screws. then put your hand inside of base of d/w +feel around for water. if you feel water there is probably a leak. i use a shop vac to remove water. once water is removed . the d/w should star to fill wih water. i usually remove outer door + metal cover behind door attached to base, gives me alot more room to look around ,use atrouble lamp to see better turn d/w on +observe where water comes out ,maybe leaking water valve on left or front sump hose .see what you see+we will take it from there
