Samsung Washing Machine Error Codes
One page per code — never a wall of codes to scroll through. Find the code on your display, open its page, and you get the manufacturer's meaning, the causes in the order Samsung checks them, the exact steps, and a plain line for where DIY stops and a technician starts.
At a glance
| Code | What it means | |
|---|---|---|
| 4C also 4E · E1 · nF | Water is not supplied — the washer is not filling correctly. | Guide → |
| 5C also 5E · nd · SC | Water is not draining from the washer. | Guide → |
| UE / Ub also UE · Ub · Ur · U6 | Spinning does not work — the load is unbalanced. | Guide → |
| dC also dE · dC1 · dL | The washer is running (or trying to run) with the door not closed and locked — on some models, an unbalanced load instead. | Guide → |
| 4C2 also 4E2 · CE · nF1 | Very hot water is arriving through the cold inlet — the hot and cold supply hoses are reversed. | Guide → |
| LC also LC1 · LE · LE1 · 1E | Water level or leakage error — moisture has been detected where it does not belong, or there is a problem with the level sensor. | Guide → |
| SUd also 5UD · Sd · 5d | Excessive suds — the washer has detected too much foam and has paused to let it settle. | Guide → |
| OC also OE · OF · 0C | Overflow error — there is too much water in the washer. | Guide → |
| 3E also 3C · E3 | Motor Driving Error — the motor is having difficulty operating. On some models, 3E is a voltage error instead. | Guide → |
| CL also Child Lock display | Child Lock display — not a fault. On newer models it follows a safety drain of the tub. | Guide → |
| 9C1 / UC also 9C1 · 9C2 · UC · PF · 9E1 · 9E2 | Voltage & power errors (9C1, 9C2, UC, PF, 9E): supply outside the safe range, or power lost. | Guide → |
| 1E / 1C also 1C · E7 | Water level sensor issue (UK/LB classification); grouped with water-level and leakage errors in US documentation. | Guide → |
| AE / AC also AC · ACb · AC6 · AE6 · 13E | Communication error between the main and sub control boards. | Guide → |
| tE also tC · EC · tE1–tE3 · tC1–tC3 | Temperature sensor error (also shown as tC or EC). | Guide → |
| bE also bE1 · bE2 · bE3 · E2 · 6E2 · 8E2 | Jammed panel button on most models; a sensor error on some. | Guide → |
| SDC also 5DC | Detergent drawer not completely closed. The fix is one line: push the drawer in until it clicks — Samsung US notes it clicks when fully closed. If it keeps happening, clean the drawer tracks. On newer AI models the display may read “Close dispenser” instead. No full page: a paragraph is all this code honestly needs. | — |
| ddC also DC3 / dC3 | The Add Door is not detected as closed and locked. The fix: check the Add Door latch is securely fixed, nothing is caught in it, and it is closed and secured correctly — the door family checks on the dC page apply. Damage to the Add Door or its latch is a service item. | — |
The dC trap — read this first if your code is dC
Samsung uses dC for two different faults: a door error on most models, and an unbalanced-load error on others. Its own guidance says so in both sections. Our dC page carries Samsung's model table so you can tell which machine you have before you start ordering parts.
No code? Start from the symptom
Three of the most-searched Samsung problems arrive without a code at all — or with a code the owner has not read yet. These pages work as decision trees and route you into the code pages above when a code turns out to be involved.
Samsung Washing Machine Won't Drain
A symptom, not a code: the washer could not empty. If a code is showing, it is usually Samsung's 5C / nd no-drain family.
Samsung Washing Machine Won't Spin
A symptom with three different problems behind it: the spin never starts, the spin runs too slowly, or the machine stops with a code. The fix depends on which one you have.
Samsung Washer Keeps Beeping
Beeping is a signal, not a fault class. When the machine beeps — at the start, mid-cycle, at the end, or non-stop — tells you what it is saying.
How the reset rule works on this site
Samsung does not publish one reset time — it publishes different waits for different code families: 1 minute in its 4C fill-error guidance, 30 seconds in its 3E guide, and 2–3 minutes for its general "all other errors" advice. Competitor sites blur these into a single invented figure, so the same site will tell you 1 minute on one page and 5 on another. We do not do that: every page on FixSignal gives you Samsung's figure for your code family, and says which document it came from.
Codes we have deliberately not published yet
HE (heater error) scored below our publishing threshold in our keyword review. A heater fault is technician-only work with little safe DIY value to add, and publishing a thin, safety-sensitive page just to have the code would make this hub worse, not better. It will be added later, in a properly safety-led format, once the hub has the authority to carry it.
Other brands
LG washing machine codes are published too — OE (drain), IE (inlet), UE (unbalance), dE (door) and LE (rotation), each checked against LG's official front-load and top-load lists: LG washing machine error codes.
Sources
Every meaning, alias and check order on this hub and its guide pages is taken from Samsung's official support documentation and model manuals, linked at the foot of each guide page. Where Samsung's regions publish different classifications for the same code, the guide page says so and prints both.
