Samsung Washer Error Code DW — AddWash Door Error
What this means
The DW error code is specific to Samsung AddWash models that feature a small door on the main door, allowing you to add forgotten items mid-cycle. This error indicates the AddWash door is not closing properly, its latch mechanism is broken, or the door switch is not detecting the closed state. The washer will not continue the cycle until the AddWash door is securely closed and detected.
Step-by-step fix
4 stepsClose the AddWash door firmly
Press the AddWash door closed until you hear a positive click. Sometimes the door does not latch on the first attempt.
Make sure no clothing or fabric is caught in the AddWash door gasket that could prevent full closure.
Check the AddWash door gasket
Inspect the rubber gasket around the AddWash door for tears, warping, or debris. Clean any detergent buildup that may be preventing a proper seal.
A small amount of fabric softener residue on the gasket can make it tacky and prevent the door from latching cleanly.
Inspect the latch mechanism
Open and close the AddWash door several times, watching the latch. If the latch hook is bent, cracked, or does not spring back, it needs replacement.
The AddWash latch is a relatively inexpensive part and easy to replace.
Test the AddWash door switch
If the door latches physically but the washer still shows DW, the door switch may be faulty. Unplug the washer. Access the switch behind the AddWash door frame and test for continuity when the door is closed.
The switch should show continuity when the door is latched and open (OL) when unlatched.
When to call a professional
If the switch and latch are good but the error persists, the control board may not be reading the switch input. A technician should diagnose the circuit.
