Why Does My Samsung Dishwasher Keep Turning Off Mid-Cycle?
2025-03-11

A Samsung dishwasher keeps turning off unexpectedly, disrupting your kitchen routine and leaving dishes unclean. Sound familiar? Samsung dishwashers are designed with advanced technology, but like any appliance, they can experience performance issues. If your dishwasher shuts off mid-cycle, there could be several potential causes. Understanding the reasons behind the problem can help determine whether a simple fix is possible or if professional repair is necessary.
Common Reasons Your Samsung Dishwasher Keeps Shutting Off
If your Samsung dishwasher keeps turning off, it may be due to mechanical issues, electrical problems, or water supply concerns. Samsung dishwashers feature advanced smart sensors and energy-efficient cycles, but when they shut off unexpectedly, it can disrupt cleaning performance and efficiency. Here are some of the most common causes and what you can do to troubleshoot the issue.

Door Latch Issues
A faulty or misaligned door latch can prevent the dishwasher from staying securely closed, causing it to stop mid-cycle. If the door latch is loose or damaged, the machine may register it as open, triggering an automatic shutdown.
What You Can Do:
- Check the door latch for damage or misalignment.
- Ensure the door closes fully and latches securely.
- Clean any debris around the latch.
- Contact a technician if a replacement is needed.
Power Supply Issues
If your dishwasher loses power unexpectedly, it may turn off mid-cycle. Loose power connections, faulty outlets, or tripped circuit breakers can all interrupt the dishwasher’s operation.
What You Can Do:
- Check if the circuit breaker has tripped.
- Avoid extension cords.
- Contact an electrician if wiring issues persist.
Control Board Malfunction
The control board is the brain of your dishwasher, managing all functions and cycles. If it malfunctions, the dishwasher may shut off mid-cycle, fail to start, or display error codes.
What You Can Do:
- Perform a network reset using the Smart Control and Hi-Temp Wash buttons (refer to your user manual for model specifics).
- If the issue continues, consult a technician for repair or replacement.
Overheating Triggers Safety Shut-Offs
Samsung dishwashers have built-in safety features that prevent overheating. If the dishwasher detects excessive heat, it may shut off to avoid damage.
What You Can Do:
- Ensure the dishwasher’s vents are clear of obstructions.
- Avoid running multiple heat-intensive cycles back-to-back.
- If overheating continues, a professional repair technician can inspect the heating elements and thermostat for faults.
Float Switch Malfunctions Can Stop Water Flow
The float switch monitors the water level in the dishwasher. If it malfunctions or becomes stuck, it may falsely signal an overflow, triggering the dishwasher to shut off.
What You Can Do:
- Check the float switch for visible obstructions, such as food debris or hard water buildup.
- Gently move the float switch to ensure it isn’t stuck.
- If the switch remains unresponsive, it may need to be replaced by an appliance repair professional.
Circulation Pump Issues and Low Water Pressure
Samsung dishwashers require adequate water pressure to function correctly. If the pressure is too low, the dishwasher may stop mid-cycle due to insufficient water flow.
What You Can Do:
- Measure water pressure with a gauge (Samsung dishwashers need 20-120 PSI).
- Ensure the water supply valve is fully open.
- Contact a plumber if the water pressure remains low.
Water Inlet Issues Can Interrupt the Wash Cycle
The water inlet valve controls the flow of water into the dishwasher. If it’s clogged or defective, the dishwasher may shut off due to insufficient water intake.
What You Can Do:
- Inspect the water inlet valve for blockages or buildup.
- Clean with a descaling solution if needed.
- Replace the valve if it’s faulty.
