What the DDC error code actually means

Your LG washer is showing DDC because the small add door built into the main washer door is open, not fully closed, or the latch that holds it shut is not working correctly. The washer stops as a safety measure to keep water inside the drum. Try firmly pressing the add door closed until you hear it click, and if that does not clear the error, the latch or sensor may need to be repaired.

Questions people ask about DDC

What does DDC mean on a LG washer?
DDC on an LG washer means the add door, which is a small secondary door built into the main washer door for adding items mid-cycle, is open or is not being detected as securely closed. The error can also indicate a problem with the add door switch, barrier, or lock module. The washer will not operate while this error is active to prevent water from leaking through the unsecured opening.
Is it safe to use my LG washer with a DDC error?
No, you should not attempt to run the washer while the DDC error is active. The error exists to prevent water from escaping through an unsecured add door during the wash or spin cycle. Running the machine with a malfunctioning add door latch or lock module could result in water leaking into the door assembly or onto the floor.
How much does it cost to repair a DDC error on an LG washer?
If only the add door switch needs replacement, parts typically cost in the range of $15 to $50 depending on the specific model. A lock module replacement can run between $40 and $100 for the part. If professional labor is involved, total repair costs including diagnosis and installation generally range from $100 to $250, though this varies by location and service provider.
How do I fix the DDC error on my LG washer?
Start by firmly pressing the add door closed until you hear or feel it click into the latched position, then restart the cycle. If the error returns, inspect the barrier for debris or damage and check that it moves freely. If the door closes properly but the error persists, the add door switch or lock module may be faulty and will need to be tested and potentially replaced.
Will resetting my LG washer clear the DDC error?
A power reset, done by unplugging the washer for about 30 seconds and plugging it back in, may temporarily clear the DDC error, but it will return if the underlying issue is not resolved. If the add door switch, barrier, or lock module is physically damaged or malfunctioning, the error will reappear as soon as the washer tries to run. The root cause must be addressed for the error to stay cleared.
