If your Kenmore washer won't stop, the most likely cause is water siphoning from the tub. Check that the drain hose ends 30 to 36 inches above the floor in a standpipe or laundry tub. The hose should not be sealed around the standpipe, and it should not be pushed too far down the drain, because either condition can make the washer keep filling and draining, causing a washer not stopping problem. If the washer drains normally but remains stuck on a cycle, a defective control board may be sending the wrong signals. Inspect the control board for burned areas or shorted components, but remember that it can be difficult to test. A failed main control board can cause the same symptom. If those boards appear sound, test the timer with a multimeter and the washer's wiring diagram, then replace it if it does not operate correctly. These parts can vary by model, so enter your Kenmore washer model number to find the exact replacement control board, main control board, or timer for your specific washing machine. Disconnect power before inspecting or replacing internal components.
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 - Kenmore Washing Machine Control Board
If the washer can successfully drain the water from the tub then a defective control board could be responsible for the washer not stopping. The control board cannot be easily tested, but you can try to inspect it for signs of burning or a shorted-out component to help determine if the part should be replaced.
