Samsung Dishwasher Won't Turn Off

Quick Answer

Most Samsung 'won't turn off' reports fall into two categories: the machine is looping through cycles and not stopping naturally, or water keeps running into the tub even after the user pressed Power. The first is a control board or cycle logic issue.

A Samsung dishwasher that won't turn off is usually caused by a stuck inlet valve filling water continuously, a control board stuck in an active cycle, or a Power button that is not registering. Holding Power for 5 seconds forces a shutdown on all Samsung models. If water keeps entering after shutdown, the inlet valve DD62-00136A is stuck open and must be replaced.

Frequently Asked Questions

How do I force a Samsung dishwasher to turn off?
Hold the Power button for 5 seconds. This overrides an active cycle and shuts the machine down. If the button does not respond, flip the circuit breaker off.
Why does water keep running into my Samsung dishwasher when it is off?
The inlet valve solenoid is stuck open. The valve diaphragm has failed and is allowing water to pass through even without an electrical signal. Turn off the supply valve under the sink and replace the inlet valve DD62-00136A.
My Samsung dishwasher cycle runs for hours. What is wrong?
Extended cycles are usually caused by a heating element that is not reaching temperature (causing the heated dry phase to loop), a soil sensor fault, or a water level sensor issue. Check if an error code appears at the end of the extended cycle.
