Speed Queen Commercial Washer won't stop

When your Speed Queen Commercial washer won't stop, first check for water siphoning from the tub. The drain hose may be positioned too low, sealed tightly in the standpipe, or pushed too far down the drain, allowing water to leave the tub continuously and making the washer keep running. The hose outlet should typically end 30 to 36 inches above the floor, depending on the model. If the washer drains normally but the washing machine won't stop, a defective control board is the next likely cause. Inspect the control board and main control board for burned areas or shorted components, although these parts are difficult to test. A faulty timer is less common, but you can test it with a multimeter and the washer's wiring diagram. This troubleshooting applies when a Speed Queen Commercial washer keeps running or is stuck on a cycle. Before ordering a replacement control board, main control board, or timer, enter your model number to find the exact part for your specific washing machine. Confirm the drain hose setup and rule out siphoning before replacing electrical 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 - Speed Queen Commercial 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.
