How Samsung Washer Codes Work
Samsung mixes two formats on its washer panels: a number followed by a letter, like 4E or 3E, and a letter-first pairing, like dE or SUD. Once you know the pattern, most codes are easier to decode than they first look. A leading number usually points at a system (4 for water supply, 3 for the motor), while the letter tags it as an error. Letter-first codes like dE (door) and SUD (suds) name the problem directly. The same core set of codes shows up across Samsung's front-load and top-load lineup, so whether you have a WF-series front-loader or a WA top-load machine in Tustin or anywhere else in the county, this reference applies.
Two things are worth knowing before you act on any code:
- A code names the system, not the severity. 4E can mean a closed valve you can open in ten seconds, or a failed inlet valve that needs a part. The code tells you where to look; your own check tells you which end of that range you're dealing with.
- Some codes are habit, not damage. SUD almost always traces back to using too much detergent, not a broken part. Rule out the simple, no-parts-needed explanation before assuming something failed.
For a Samsung washer that's shaking hard, leaking, or won't power on at all, beyond a single code on the display, our washer repair service in Orange County carries the pumps, valves, and control boards these repairs usually call for.
Code-by-Code Reference
Not Draining
What it means: Water isn't draining out of the tub at the expected speed, or the machine can't confirm it emptied.
We've written up the full walkthrough for this one already, the pump filter, the drain hose, and the coin trap, in our Samsung washer not draining guide, so we won't repeat every step here. Start there if this is your code; if the basic checks in that guide don't clear it, the drain pump has usually failed.
Water Supply Error (Not Filling)
What it means: The washer isn't sensing water coming in fast enough, or at all, within the time it expects.
Check first: Make sure both the hot and cold supply valves behind the machine are turned fully open, not just cracked. Look for a kink in either fill hose. Then shut the valves off, disconnect the hoses, and rinse out the small mesh inlet screens where they thread into the washer, hard Orange County water leaves mineral sediment there faster than most people expect.
If 4E returns after cleaning: The water inlet valve has likely failed and needs replacement.
Repair cost: $150–$300. Estimates vary by brand, part availability, and diagnosis. Final quote is provided before repair.
Hot and Cold Supply Reversed
What it means: The washer detects that the hot and cold connections are swapped, usually because a hose was reconnected wrong after the machine was moved, installed, or serviced.
Fix: Turn off both valves, disconnect the two fill hoses at the back of the washer, and reconnect them correctly, blue-marked hose to the cold valve, red-marked hose to the hot valve. This is a five-minute fix with no parts involved.
Unbalanced Load
What it means: The load is sitting lopsided in the drum, so the machine won't ramp up to a full spin.
Check first: Open the door and spread the laundry out. A single heavy item, a comforter, a bath mat, a hoodie that's balled up in one spot, is the usual cause; toss in a towel or two to even it out. Confirm the washer isn't rocking (adjust the leveling feet if it is).
If UE keeps appearing on loads that look balanced: The suspension, shock absorbers or springs, is worn, or the machine isn't sitting level on the floor. Both point to a technician visit.
Repair cost for suspension components: $200–$450. Estimates vary by brand, part availability, and diagnosis. Final quote is provided before repair.
Door Not Sensed Closed or Locked
What it means: The washer can't confirm the door is fully shut and latched, so it won't begin filling.
Check first: Open the door and push it closed firmly until it clicks. Check that nothing, a sleeve, a stretched fold of the door gasket, is caught in the gap and keeping the latch from seating.
If dE persists: The door lock assembly has failed and needs replacing. It's a common wear part on front-load machines.
Repair cost: $150–$300. Estimates vary by brand, part availability, and diagnosis. Final quote is provided before repair.
Excess Suds
What it means: The washer's sensors detect more suds than the cycle can rinse out properly, so it pauses to add extra rinses or stops the cycle.
Check first: Too much detergent, or a non-HE detergent in a machine that requires HE, is almost always the cause. Cut the amount back (most people use two to three times more than needed) and switch to an HE-rated detergent if you haven't already.
No technician needed in the vast majority of cases; this is a usage fix, not a parts failure.
Motor Error
What it means: The motor isn't turning the way the control expects, often flagged by the Hall sensor that tracks motor position, or by something restricting the drum.
Check first: Power the washer off and check that nothing, a stray sock, an underwire, a small toy, is jamming the drum from turning freely. Power-cycle and run a short cycle.
If 3E returns: The motor or its Hall sensor needs testing and likely replacement. This is a technician repair.
Repair cost: $250–$500. Estimates vary by brand, part availability, and diagnosis. Final quote is provided before repair.
Sensor, Panel, Heater, and Overflow Faults
tE (temperature sensor): The thermistor that reads water temperature is reporting bad data. Usually a technician job to test and replace the sensor. Repair cost: $150–$275.
bE2 (control panel / stuck button): Often caused by moisture on the panel, a damp finger, a splash, humidity, making a button read as stuck. Power the washer off, work the button a few times, and dry the panel thoroughly before powering back on. Rarely needs a technician.
HE (heater error): The heating element or its wiring isn't performing as expected. This is a technician repair. Repair cost: $200–$400.
OE (overflow): The washer senses more water than the cycle called for, often because a water valve is stuck open. Shut off the supply valves if the machine is actively overfilling, then call for service; this can tie back into the main control board. Repair cost: $250–$500.
Estimates vary by brand, part availability, and diagnosis. Final quote is provided before repair.
Quick Reference: Reset vs Repair
Not every code means a service call. Here's what's worth trying yourself versus what points to a technician.
| Code | What it points at | DIY step worth trying |
|---|---|---|
| nd / 5E / SE / 5C | Drain | See our not-draining guide |
| 4E / 4C / nF | Water supply / fill | Open both valves fully, clean inlet screens |
| 4E2 / 4C2 / CE | Hoses reversed | Reconnect blue-to-cold, red-to-hot |
| UE / Ub / Ur / U6 | Unbalanced load | Redistribute laundry, level the machine |
| dE / dC / dC1 | Door not sensed | Check for caught clothing, reseat the door |
| SUD / Sud / 5D | Excess suds | Cut back detergent, switch to HE-rated |
| tE / tE1 / tC | Temperature sensor | Power-cycle once; usually a technician job |
| 3E / 3C | Motor error | Check nothing jams the drum |
| bE2 / 6E2 / 8E2 | Control panel / stuck button | Power off, work the button, dry the panel |
| HE / HC | Heater | Power-cycle; usually a technician job |
| OE / 0E / OC | Overflow | Shut off supply if actively overfilling, call for service |
We see these Samsung codes across the county every week, from Tustin to Irvine and the coastal cities. If your machine needs more than a code check, worn door boots, motor diagnostics, a full inspection, our Samsung appliance repair team handles the brand's full appliance lineup, not just washers.

Our company diagnostic fee is $99 flat, and it's credited toward the repair if you move forward. For context, a new Samsung front-load washer typically runs $650 to $1,500, so most single-fault repairs, a valve, a door lock, a drain pump, are clearly worth doing. The math only gets close when the motor or control board fails on an older machine. For a full breakdown across appliances, see our Orange County appliance repair pricing guide.
One thing worth knowing: suds or standing water left in the drum for a few days invites mildew in the gasket, especially on front-load Samsungs with a rubber door boot. If you can't clear a drain fault right away, bail out the water so the drum isn't sitting full while you wait for a repair.

Book a Repair VisitFrequently Asked Questions
How do I clear an error code on my Samsung washer?
Power the washer off, wait about 30 seconds, then power it back on and start a new cycle. This clears a code caused by a one-time glitch. If the same code returns right away, the underlying condition, a blocked hose, an unbalanced load, or a stuck button, is still there, and the reset alone won't fix it.
Is a Samsung 4E error serious?
Usually not on its own. 4E most often means a closed valve, a kinked hose, or a clogged inlet screen, all quick DIY checks. But if 4E won't clear after you've checked the valves and screens, it can point to a bigger water-supply problem, very low household pressure or a frozen or burst supply line, and is worth a closer look.
What does 5E or nd mean on a Samsung washer?
5E and nd both mean the washer isn't draining the water out of the tub. We cover the full step-by-step fix, the pump filter, the drain hose, and the coin trap, in our Samsung washer not draining guide, so we won't repeat it here. If the basic checks in that guide don't clear it, the drain pump has likely failed.
Why does my Samsung washer keep showing a UE (unbalanced) error even with a normal load?
Bunched-up heavy items, a comforter, a bath mat, a hoodie balled into a corner, are the most common cause, even in a load that looks normal-sized. If UE keeps appearing on loads you know are spread out evenly, the suspension rods or shocks are likely worn, or the washer isn't sitting level on the floor, and both call for a technician to sort out.
