On Samsung washers, 4C/4E means water isn't coming in, 5C/5E means it isn't draining, dC/dE/dL means the door or lid isn't locked, UE/Ub means an unbalanced load, Sd/SUd means too many suds and 1C/LE/LC means water where it shouldn't be or a sensor fault. Start by powering off for 2–3 minutes, opening both faucets, checking hoses and cleaning the drain filter. Motor (3C/3E), heater (HC) and sensor (tC, 8C) codes usually need a technician.
| Code | What it means | What you can do |
|---|---|---|
| 4C / 4E / nF | Water isn't entering correctly | Open faucets, clean the inlet hose screens, check hose kinks. A drain hose placed too low can siphon water out and trigger it. |
| 4C2 / 4E2 | Very hot water on the cold inlet — hoses swapped | Swap the hot and cold hoses. |
| 5C / 5E / nd | Water isn't draining (or too slowly) | Clean the drain filter, straighten the drain hose. If the pump hums or is silent, it needs replacing. |
| OE / OC | Too much water in the tub | Turn off the faucets. Usually a stuck inlet valve or water level sensor — call. |
| 1C / 1E / LC / LE | Water detected where it shouldn't be, or a sensor fault | Check under the washer for leaks. Repeats need diagnosis. |
| Code | What it means | What you can do |
|---|---|---|
| dC / dE / dL / LO | Door or lid not closed or not locking | Close firmly; remove clothing caught in the gasket. Repeats mean the lock assembly. |
| UE / Ub / Ur | Load is unbalanced | Redistribute the load; avoid washing one heavy item alone; level the washer. |
| Sd / SUd | Too many suds — the cycle pauses to clear them | Use HE detergent at the low line. Hard Las Vegas water tempts people to overdose. |
| Code | What it means | What you can do |
|---|---|---|
| 3C / 3E | Motor malfunction (on some models voltage) | Power off and restart; repeats need diagnosis. |
| HC / HE | Heater malfunction | Technician repair. |
| tC / tE | Temperature sensor fault | Technician repair. |
| 8C / 8E | Vibration (MEMS) sensor error | Technician repair. |
| 9C1 / PF / UC | Abnormal voltage or power failure | Make sure the washer is on its own outlet, not an extension cord. |
| AC | Communication error | Power off 2–3 minutes; repeats need diagnosis. |
Codes and their meaning can vary by model and production year, and the same code can have different causes. Where sources disagree we say so; in every case the exact cause is confirmed only by a technician's on-site diagnosis. Your owner's manual has the definitive list for your model.
Unplug the appliance (or switch off its breaker) before touching anything inside it, and never open a sealed refrigeration system, a gas valve or a microwave. If a code points to a part, the part has to be tested before it is replaced; we do that on the $75 diagnostic visit, credited toward the repair.
Turn it off for 2–3 minutes, turn it back on and restart the cycle.
It isn't draining. Clean the drain filter and check the drain hose; a failed pump is the next suspect.
On most models the door isn't locked; on some it's an unbalanced load — check your manual.
