LG Washer Error Code 1dC4

The 1dC4 code on an LG washer means the control system has detected that the inner door of the upper washer compartment is open or not properly latched. The washer will not run a cycle until it can confirm the inner door is fully closed. This is a safety interlock designed to prevent operation with an unsecured door. Closing the inner door firmly and pressing START/PAUSE is the first step to clear the error.

No, the washer will not operate while the 1dC4 error is active because it cannot confirm the inner door is securely closed. Attempting to bypass this fault is not recommended, as running the machine with an unsecured door could result in water leakage or injury. Resolve the door issue before running any wash cycle.

If the fix is simply closing the inner door properly, there is no cost involved. If the door latch assembly needs replacement, parts typically range from $15 to $60 depending on the specific model. A door switch replacement is generally in the $10 to $40 range for the part. Adding professional labor, total repair costs can range from $100 to $200 or more depending on your location and the technician's rates.

Start by opening and firmly re-closing the inner door of the upper washer compartment, making sure it clicks into the latch. Check for any clothing, debris, or residue that might be blocking the latch from engaging. Press START/PAUSE after closing the door to see if the error clears. If the code returns, inspect the door latch assembly and door switch for damage or failure, as one of those components may need to be replaced.

A reset alone will not permanently clear the 1dC4 code if the underlying door issue has not been resolved. The error will return as soon as the washer checks the door status again. You need to address the root cause, whether that is an unlatched door, a blocked latch, or a faulty door switch, before the code will stay cleared.
