Samsung Washer Error Code 1DC4

The 1DC4 code means the upper washer's inner door is detected as open or not properly latched. Samsung's dual-drum washer models use a separate door switch on the upper unit to confirm closure before allowing operation. The machine will not run the upper drum until this condition is resolved.

A power reset by unplugging the washer for a few minutes may temporarily clear the displayed code, but if the underlying cause is a faulty latch or door switch, the error will return as soon as you attempt to start a cycle. The root cause must be addressed for the fix to be permanent.

If the fix is simply closing the door properly, there is no cost. If the door latch assembly or door switch needs replacement, parts typically range from $15 to $60 depending on the component. Adding professional labor for diagnosis and installation can bring the total repair cost to somewhere between $100 and $250.

Start by firmly closing the upper inner door until it clicks, then press the START/PAUSE button. If the error persists, check for obstructions in the door frame or gasket. If the door appears to close correctly but the code returns, the door latch assembly or door switch may need to be inspected and possibly replaced.

The upper washer unit will not operate while this error is active, which is a safety measure to prevent the machine from running with an open door. The lower drum may still function depending on your model. Do not attempt to bypass the door switch, as operating with an unsecured door is a safety hazard.
