Samsung Washer Error Code DC2

DC2 means the washer detected that the door did not successfully lock after the door was closed. The control board sends a lock command and waits for a confirmation signal from the door lock assembly, and DC2 triggers when that confirmation is never received. This code is especially common during boil wash cycles, where internal pressure from high temperatures can push the door outward and prevent the latch from seating fully. The washer stops operation until the lock condition is resolved.

No, you should not continue running the washer with an active DC2 code. The error means the door lock did not confirm engagement, and running a wash cycle without a confirmed locked door is a safety hazard due to the risk of the door opening under water pressure or steam. The washer is designed to halt operation when this condition is detected, and that behavior should be respected until the fault is diagnosed and repaired.

Repair costs depend on the root cause. If the fix is a wiring reconnection or a door alignment adjustment, the cost may be minimal beyond your time. Replacing a door lock assembly typically involves part costs in the range of $25 to $80 for the component, with professional labor adding $75 to $150 depending on your area and the service provider. If the main control board is involved, costs can be considerably higher, though the control board is rarely the primary cause of DC2.

Some causes of DC2 are DIY-friendly. Start by checking whether the error only occurs during high-heat cycles, which may simply require reducing load size to relieve pressure on the door seal. Also check that the power cord is firmly connected and inspect wiring connectors at the door lock for looseness or corrosion. If the door lock assembly itself has failed electrically, replacing it is a moderate DIY repair that requires disconnecting power, removing the door seal, and swapping the lock unit.

A reset may temporarily clear the code, but it will return if the underlying problem is not addressed. To reset, unplug the washer for a few minutes and then reconnect power. If the door lock mechanism or wiring has an actual fault, the DC2 error will reappear as soon as the washer attempts to lock the door again. A reset is useful for confirming whether the fault is intermittent, but it is not a fix.
