A Samsung washer error code is not a breakdown warning, it is the machine pointing at the one part it is unhappy with. Most codes trace back to something you can check in a few minutes, like a clogged filter, a kinked hose, or a load that spun off balance.
Before you brace for a big repair bill, try the fix that clears the most codes first. Cut the power at the outlet or the breaker, leave it off for a couple of minutes, then switch it back on and restart the cycle. If the same code returns, this guide explains what it means and how to clear it.
The codes read the same whether you own a front loader, a top loader, or an Eco Bubble model. One tip before you look yours up: newer Samsung machines end their codes in the letter C (4C, 5C) while older ones used E (4E, 5E) for the identical fault, so go by the number if the letter does not match a chart.
Key Takeaways
- Most Samsung washer codes name the part or step at fault, such as the water supply (4C), drainage (5C), a locked door (dC), or an unbalanced load (Ub), so the code itself tells you where to look first.
- An unbalanced load (Ub, Ur, or UE) is the most common spin-cycle stop, and it clears once you open the door, spread the wet laundry evenly around the drum, and check that the machine sits level.
- The debris filter and the drain hose sit behind the whole no-drain family (5C, 5E, SE, and nd), so clean the filter and straighten the hose before you suspect the pump.
- Codes ending in C are the newer labels for faults older machines showed with an E, and cutting power for 1 to 5 minutes clears a frozen display or a stuck cycle, according to Samsung’s reset guidance.
Samsung Washing Machine Error Codes and Troubleshooting
Samsung washing machine codes look cryptic, but each one usually points to a specific, fixable problem. Below are the common codes, what they mean, and the steps that clear them.
You may see two codes for the same fault, like 5E and 5C. Samsung changed its coding system over the years, so older models show “E” and newer ones show “C”, and the fix is identical either way (1).
There is a rough dividing line in every entry below. Anything involving the load, the filter, the hoses, or the taps is yours to fix in an afternoon. A failed sensor, pump, motor, or control board is where a technician and a part number take over.
Error Code 5C, 5E, or SE
What It Means: Drainage Issue. Water is not leaving the washer at the correct speed, or it is not leaving at all, so the cycle stalls with the drum still full.
Solution: Start with the debris filter behind the small panel at the bottom front of the washer, and clear out the lint, coins, and buttons that collect there. Next, inspect the drain hose: it should run without kinks, sit no more than a few inches inside the standpipe, and have no soft clog you can feel by squeezing along its length. Check the standpipe itself too, since a blocked house drain stops the pump just as effectively as a blocked hose. If the filter and hose are clear and the drum still holds water, the drain pump or its impeller is the likely fault and needs replacing.
Error Code Ub, Ur, or UE
What It Means: Unbalanced Load. The washer tried to spin, the weight sat on one side of the drum, and it stopped rather than wobble itself across the floor. A Ur code (Unbalanced Load Retry) is the gentler version: the machine adds water and tries to rebalance the load on its own before spinning again.
Solution: Pause the cycle, open the door, and spread the wet laundry evenly around the drum instead of leaving it bunched on one side. Check that the machine does not rock when you push a corner, and adjust the feet until it sits solid. A single heavy item, like a bath mat, a hoodie, or one pair of jeans, is the usual trigger, so add two or three towels to give the drum something to balance against.
Error Code 4C or 4E
What It Means: Water Supply Issue. Water is not entering the machine correctly, either not at all or too slowly for the cycle to continue.
Solution: Check that both taps on the wall are fully open, not cracked half a turn. Turn the water off, unscrew the fill hoses at the machine, and clean the mesh filters inside the inlet valve connections, where sediment and rust flakes collect. Make sure the hoses are not kinked or pinched behind the washer. If the supply is good and the mesh is clean, the water level sensor or the inlet valve itself is the next suspect.
Error Code 8C or 8E
What It Means: Mems Sensor Error. This is the motion and vibration sensor that keeps the drum from shaking too hard. Some models label it a vibration sensor error, and on others the same code points to a bad tacho signal coming from the motor.
Solution: Redistribute the load first and make sure the washer is level and not pressed against a wall or a cabinet, since heavy vibration on its own can trip the sensor. If the code stays after a full power-off, the wiring between the sensor and the control board may be loose. A sensor that is securely connected and still failing needs a technician, and so does a motor throwing a bad tacho signal.
Error Code dC, dE, dL, FL, or LO
What It Means: Door Issue. The washer cannot confirm the door is closed and locked, so it refuses to fill or spin. On a few models dC and dE flag an unbalanced load instead, so check the manual for your model number before you order a latch.
Solution: Open the door and close it again firmly. Look for a sleeve, a sock, or a corner of a duvet caught in the latch or the rubber gasket, and wipe the latch contacts with rubbing alcohol if they look dull or grimy. If the code persists with the door plainly shut, the latch assembly or a dropped hinge is the fault, and that is a replacement part rather than an adjustment.
Error Code Sud, SUd, or 5d
What It Means: Excessive Suds. The washer detected an over-sudsing condition and paused itself so the foam can collapse before the cycle continues.
Solution: Let it sit. The machine usually clears this on its own once the foam settles, then finishes the cycle. To stop it happening again, use only High Efficiency (HE) detergent and use less of it than the cap suggests, since standard detergent and generous doses both produce more foam than a modern drum can handle. Running one rinse-only cycle on an empty drum helps flush the residue out after a heavy sudsing episode.
Error Code 1C, 1E, or IE
What It Means: Water Level Sensor Failure. The pressure sensor that tells the board how much water is in the tub is reading an abnormal value, so the washer cannot judge when to stop filling.
Solution: Check the wire harness running from the pressure sensor to the main board, and reseat any connector that has worked loose. Look at the small clear tube between the sensor and the tub as well, since a kink or a plug of detergent scum in that tube gives the same false reading. If the connections and the tube are clean, the sensor itself is defective and needs swapping out.
Error Code nF
What It Means: No Fill. The washer asked for water, waited, and never got enough.
Solution: Treat it like a 4C. Verify both the hot and cold valves are open, then disconnect the hoses and clean the inlet mesh filters. If you use flood-safe hoses, check them next, since they can sometimes be the cause even though the tap is open. Resetting or replacing those hoses with standard rubber or braided ones usually clears it.
Error Code LC or LE
What It Means: Leakage Detected. This sits in the same family as the 1C and 1E codes. The washer sensed moisture where it should not be, or the water level sensor is reporting a leak that is not there.
Solution: Look for puddles under and behind the machine, and dry the floor so you can tell fresh water from old. Check that the drain hose connection is tight and that the debris filter cap is screwed fully home, since a loose cap weeps slowly and trips the sensor. If water is pooling from underneath, an internal hose or the tub itself may be cracked and needs a technician. If everything is bone dry, the pressure sensor is giving the false reading.
Error Code OE, 0E, OC, or 0C
What It Means: Overflow Error. There is more water in the washer than the cycle called for.
Solution: Turn off the taps and power the machine down first, before you diagnose anything. The usual causes are an inlet valve stuck in the open position or a pressure sensor that has stopped reading the true level. Here is the quick test: if the drum keeps filling while the washer is unplugged, the inlet valve is mechanically stuck and needs replacing. If it stops, the sensor is the fault.
Error Code nF1 or 4E2
What It Means: Hot and Cold Hose Reversal. The machine is detecting hot water arriving at the cold valve, or the other way round.
Solution: Check the connections at the wall and at the back of the machine. The red hose belongs on the hot tap and the blue hose on the cold, at both ends. This one shows up most often right after a delivery or a move, so it is worth checking first if the code appeared on a brand new install.
Error Code tE, tE1, or tC
What It Means: Temperature Sensor Error. The thermistor that reads water temperature during the cycle is returning an abnormal value, too high or too low to be real.
Solution: Power the machine down completely and restore it, since a one-off misread does happen. If the code returns, the thermistor or the heating element it monitors is the fault, and both are technician jobs on most models. A washer that fills but never warms up on a hot cycle points at the same pair of parts.
Error Code nd
What It Means: No Drain. A specific variant of the 5C and 5E family.
Solution: Clean the debris filter at the bottom front of the unit, then check the drain hose is not pushed too far into the standpipe, which siphons water back and confuses the pump. The hose should reach into the standpipe far enough to stay put and no further. If the drum drains when you lower the hose into a bucket, the fault is the standpipe or the house drain, not the washer.
Error Code 3E, 3C, or E3
What It Means: Motor Error. The control board is not getting the signal it expects from the motor tachometer. Some models report the same condition as a voltage error.
Solution: Overloading is the innocent explanation, so pull out a third of the clothes and restart the cycle. If the drum turns freely by hand but will not spin under power, the fault is electrical rather than mechanical: worn motor brushes, a failed capacitor, or the board itself.
Error Code Hr, HC, HE, or HE1
What It Means: Heater Error. On models that heat their own water, the heating element or the part of the board controlling it has failed.
Solution: Power the washer down and restore it once, to rule out a glitch. If the code remains, this is a hardware fault rather than a setting, and the repair is a new heating element or a new main PCB (Printed Circuit Board). In the meantime, cold and warm cycles usually still run, so you are not without a washer while you wait for the part.
How Do I Reset My Samsung Washer?
Reset a Samsung washer by cutting its power, not by hunting for a reset button, because these machines do not have one: switch the washer off at the outlet or the breaker, leave it off for 1 to 5 minutes so the stored charge clears, then restore the power (2).
The waiting is the part people skip, and it is the part that matters. The control board holds a charge for a moment after the power goes, so a quick flick of the breaker often leaves the same fault sitting in memory.
Follow these steps for a hard reset:
- Unplug the washing machine from the wall outlet, or flip its circuit breaker to the “OFF” position.
- Leave it off for 1 to 5 minutes so the charge in the capacitors drains away and the board clears.
- Plug the machine back in, or flip the breaker back on.
- Run a short spin or rinse cycle and watch whether the code comes back.
A reset clears a one-off glitch, nothing more. If the same code appears on the next cycle, treat it as a real fault and work through the checks for that code above.
How Long Do Samsung Washers Last?
A well-maintained Samsung washer generally lasts around a decade, and careful use can stretch it further.
To get there, avoid overloading the drum, run the Self Clean cycle monthly, keep the debris filter clear, and level the machine so the drum is not fighting itself on every spin. Running calibration mode after you install or move the washer helps too, since it teaches the machine to read load weight from where it now stands. Once a unit is past ten years old and facing a repair that would cost more than half the price of a new machine, replacing it is usually the smarter move.
