If your washer won't stop, keeps running, or your washing machine is stuck on a cycle, start by checking for water siphoning from the tub. The drain hose outlet should end 30 to 36 inches above the floor in a standpipe or laundry tub. A hose placed too low, sealed tightly at the standpipe, or pushed too far down the pipe can pull water from the tub and make the washer continue filling and draining. If the washer drains normally, a faulty control board is the next most likely cause. Inspect the control board for burned areas or shorted components, although it cannot be tested easily. A defective main control board can cause the same washer not stopping problem. Less commonly, the timer may be stuck and fail to advance. You can test the timer with a multimeter and the wiring diagram, then replace it if defective. Enter your washing machine model number to find the exact control board, main control board, or timer replacement part for your specific washer.
01 - Water siphoning from tub
If the water is siphoning from the tub the outlet end of the drain hose is likely lower than the water level in the tub. The drain hose should terminate between 30 inches to 36 inches (77 centimeters to 92 centimeters) above the floor, depending on the model, in a standpipe or laundry tub. If the drain hose is sealed at the top of the standpipe or excess hose is pushed too far down into the pipe, siphoning can also occur.

02 - Universal Washing Machine Timer
If the washer can successfully drain the water from the tub then a defective timer could be responsible for the washer not stopping. You can test the timer by using a multimeter and consulting the wiring diagram. If the timer is defective, replace it.
