Samsung Washing Machine SDC Error
Also shown as: 5DC
What to check first
- Push the detergent drawer in until it clicks — Samsung: “The detergent drawer will click when it is completely closed.”
- Close the drawer before you start the machine — Samsung's manual note ties this message to a drawer that is not completely closed.
- On newer models there may be no code at all: the display reads “Close dispenser” (or “Dispenser is open”) instead — same drawer, same fix.
SDC is the shortest entry in Samsung's entire code list. Its US and Latin support pages give it exactly one sentence — the detergent drawer is not completely closed — and one confirmation: the drawer clicks when it is completely closed. There is no second meaning hiding behind it and no repair procedure attached to it, so this page is short on purpose: everything below is Samsung's wording, plus the two places owners actually get stuck — the lookalike suds code, and the sentence-form messages on newer machines.
Do not confuse SDC with SUd. They share letters and nothing else: SDC (and 5DC) is about the drawer; SUd (5UD, Sd, 5d) is the excessive-suds message, where the washer pauses to let foam settle. Read the middle character carefully — a C is the drawer, a U is the suds.
Safety first
- The drawer runs on plastic runners — never force it. If it will not click shut, something is obstructing it or the drawer itself is damaged, and forcing it can break the part the machine reads.
- Do not tape or wedge the drawer shut to silence the code. A drawer that is not genuinely closed can spill detergent and water down the front of the machine — the code is the machine asking for the real fix.
- Stop condition: stop using the machine and unplug it — and do not run it again until it has been checked — if you smell burning, see smoke, find damaged electrics (a scorched plug, a melted or cut cable), or water is leaking in quantity.
Common causes
Drawer not pushed fully home
Samsung's meaning is literal: the drawer is not completely closed. Its manual adds the test — push the detergent drawer all the way to the end, and you will hear a click when the drawer is properly closed. No click means not closed, however shut it looks.
Drawer open when the cycle was started
Samsung's manual note: the “Close dispenser” message appears if the detergent drawer is not completely closed, and the drawer should be closed before you start the washing machine. A cycle started with the drawer even slightly ajar stops at this code.
The same condition in words, not a code
Current Samsung manuals show this condition as a sentence instead of a code: “Close dispenser” on auto-dispenser models, “Dispenser is open” in other manuals. It is SDC in sentence form, not a second fault.
Step-by-step checks
- Push the drawer in until it clicksSamsung's whole fix. Push the detergent drawer all the way to the end of its travel — it will click when it is completely closed.
- Start (or restart) the cycle with the drawer closedSamsung's manual instruction is to close the detergent drawer before you start the washing machine. With the drawer clicked shut, start the cycle and the message should not return.
- Read sentence messages as the same codeIf your display says “Close dispenser” or “Dispenser is open” instead of SDC, do the same two steps — it is the same drawer condition in words.
When to call a technician
Samsung publishes no repair procedure for SDC and attaches no service instruction to it — for a drawer that clicks shut, there is nothing to repair.
If the drawer is fully closed — clicked — and SDC still shows, or the drawer is cracked or will not stay closed, Samsung's documentation for this code has ended: the drawer or the sensor that reads it needs to be checked, and that is a service item. Quote the code (SDC / 5DC) when you book.
Model differences
| What you see | What it means | Do this |
|---|---|---|
| SDC or 5DC | Detergent drawer error — the detergent drawer is not completely closed (Samsung US and Latin wording). | |
| “Close dispenser” on the display | The same condition in words — Samsung's current manuals use this message on auto-dispenser models. | |
| “Dispenser is open” on the display | The same condition in words, used in other Samsung manuals. | |
| SUd, 5UD, Sd or 5d | Not this code — excessive suds. The washer has paused to let foam settle and continues on its own. |
One-page checklist — SDC
- Drawer pushed in until it clicked
- Drawer closed before the cycle was started
- “Close dispenser” / “Dispenser is open” read as the same code
- SDC not confused with SUd (the suds code)

Frequently asked questions
Is SDC the same as SUd?
No. SDC (and 5DC) is the detergent drawer error — the drawer is not completely closed. SUd (5UD, Sd, 5d) is the excessive-suds message, where the washer pauses to let foam settle. The displays look alike at a glance; check the middle character — C for the drawer, U for the suds.
The drawer looks shut. Why does SDC keep showing?
Samsung's test is the click, not the look: the detergent drawer will click when it is completely closed. Push it all the way to the end of its travel. If it clicks shut and the code still shows, Samsung publishes no further step for SDC — the drawer or its sensor needs to be checked.
My washer says “Close dispenser” instead of a code. Is that SDC?
Yes — the same condition in sentence form. Samsung's current manuals use that message (and “Dispenser is open” in other manuals) where other models display SDC.
Does SDC mean something is broken?
Not by itself. Samsung defines SDC as the drawer not being completely closed — a state you fix by pushing the drawer in until it clicks. It only becomes a service question if the drawer is damaged or the code survives a properly clicked-shut drawer.
