Samsung Dishwasher Error Code dC

The dC code means the dishwasher detected that the door was opened while a cycle was in progress. The control board halts all operation when the door latch switch signals an open state to prevent water from spraying out and to protect the pump and heating element. It is a protective pause, not necessarily a sign of a broken part. If the door was not intentionally opened and the code keeps returning, a faulty latch or switch may be the cause.

The dishwasher stops operation automatically when the dC code triggers, so there is no immediate safety risk from the code itself. However, if the code is appearing because the door latch is failing to hold the door shut, running the unit repeatedly could eventually allow water to leak out during a cycle. It is best to confirm the latch is functioning properly before continuing regular use.

If the issue requires replacing the door latch assembly or door latch switch, parts typically range from around $15 to $60 depending on the specific component. Professional labor to diagnose and replace the latch or switch generally adds $75 to $150 or more depending on your location and service provider. If the wiring harness needs repair or replacement, costs can vary further. Diagnosing the specific failed component first will help narrow down the total repair expense.

Press the Start key to turn off the code display, then firmly close the door within 3.7 seconds to allow the cycle to resume. If the code clears and the dishwasher runs normally, no further action is needed. If the code reappears without you opening the door, inspect the door latch assembly, door latch switch, and the wiring harness connected to the switch for wear, damage, or loose connections.

Pressing the Start key clears the code display and, if the door is closed within 3.7 seconds, resumes the cycle. A full power reset by unplugging the unit or tripping the circuit breaker can also clear the code, but if the underlying cause is a faulty latch switch or wiring issue, the code will return once the next cycle begins. Resetting addresses the display, not the root hardware problem.
