What the dW error code actually means

The dW code means your dishwasher thinks the door is open while it is trying to run a wash cycle, so it stopped to prevent water from leaking out. This could be as simple as the door not being fully closed, or it may point to a problem with the latch or the switch that tells the dishwasher the door is shut. Checking that nothing inside is blocking the door from clicking completely closed is the right place to start.

Questions people ask about dW

What does dW mean on a Samsung dishwasher?
The dW code on a Samsung dishwasher means the appliance detected that the door was open during an active wash cycle. The dishwasher halts operation when this happens to prevent water from escaping the wash chamber. The warning can be triggered by a door that is not fully closed, a faulty door lock switch, or in rarer cases a problem with the main control board.
Is it safe to use my Samsung dishwasher when the dW code appears?
The dishwasher will not run while the dW code is active, which is the intended safe behavior. You should not attempt to bypass the door interlock, as running the machine with an unlatched door can result in hot water and steam escaping and causing burns or water damage. Resolve the door or switch issue before resuming use.
How much does it cost to repair a Samsung dishwasher showing dW?
If the fix is simply re-closing the door or clearing an obstruction, there is no cost. A replacement door lock switch typically runs in the range of $15 to $50 for the part, with labor adding $75 to $150 if a technician is needed. A main PBA replacement is more expensive, generally ranging from $100 to $250 for the part alone, making professional diagnosis worthwhile before replacing the board.
How do I fix the dW error on my Samsung dishwasher?
Start by opening and firmly re-closing the door, making sure nothing inside the tub is blocking the latch from fully engaging. If the code returns, inspect the door latch and lock switch for visible wear or damage. A technician can test the switch for proper continuity and replace it if needed, and the main PBA can be evaluated if all other components check out.
Will resetting my Samsung dishwasher clear the dW code?
A reset may clear the code temporarily, but if the underlying door or switch issue is not resolved the code will return as soon as the next wash cycle begins. To reset, press and hold the Start button for a few seconds or disconnect power for a minute. A permanent fix requires addressing the latch, switch, or board causing the fault.
