What does ddC mean on a Samsung washer?

ddC means: AddWash door or upper washer latch error. The most likely parts involved are AddWash door latch assembly, upper latch rubber button.

How much does it cost to fix ddC?

A typical door / door lock repair costs about $150–$400 nationally, parts and labor included. This is a reference range, not a quote — local prices vary.

Can I still use my Samsung washer with a ddC code?

The washer will usually not start or keep running while it shows ddC, because it cannot confirm the Add Door is locked. Once the door is closed properly or the faulty part is replaced, it should run normally.

Does ddC mean the main door is broken?

Not usually. The ddC code points to the small AddWash door or, on FlexWash models, the upper washer latch. A problem with the main door lock typically shows a different code, so check your model's manual or model number to be sure.

Samsung Washer ddC Error Code

AddWash door or upper washer latch error

Applies to: Front-Load AddWash and FlexWash models. May also appear as dC3, 1dC4.

What's going on

The ddC code on a Samsung washer means the washer cannot confirm that the small AddWash door is closed and locked. On FlexWash models, it can also mean the rubber button on the upper washer latch is missing. Often the fix is as simple as closing the Add Door firmly, but a worn latch or missing button may need a replacement part.

This code applies to Samsung front-load AddWash and FlexWash models. AddWash washers have a small extra door in the main door. It lets you add items after a cycle starts. Before the washer runs, it checks that this small door is fully closed and locked so water cannot spill out.

If the latch does not report that the Add Door is shut and locked, the washer stops and shows ddC. On FlexWash models, the upper washer has a latch with a small rubber button. If that button is missing, the washer may not sense the latch correctly and can show the same code. Codes can differ between model generations, so confirm with your model number.

Likely causes

AddWash door latch assembly — If the latch is worn, broken, or not catching, the washer cannot detect that the Add Door is closed and locked. That triggers the ddC code.
upper latch rubber button — On FlexWash models, the upper latch uses a small rubber button. If it falls off or goes missing, the latch may not register correctly and the washer shows ddC.

The same code can mean different things on different model generations. Check the model number on your washer's rating plate before ordering parts.

Can you fix it yourself?

Doable for an experienced DIYer with the right part, but many people still call a technician.

Safe things to check first

Open the small AddWash door and close it again firmly until you hear or feel it click shut. Then try starting the cycle again.
Look around the Add Door edges and latch area for clothing, lint, or debris that could stop it from closing all the way.
On FlexWash models, look at the upper washer latch to see if the small rubber button is still in place. Check the floor and inside the door area in case it fell off.
Power-cycle the washer by unplugging it or switching off its breaker for a minute, then turn it back on. Always unplug it or switch off the breaker before touching anything inside the door or latch area.

When to call a technician

Call a qualified appliance technician if ddC keeps coming back after you close the Add Door firmly and check for blockages and the rubber button. A handy owner may be able to replace the latch or button with the correct part for their model, but get help if you are not comfortable doing it.
