Samsung produces two main washer lines: front-load machines (WF series) and top-load machines (WA series). Each uses its own error code system. This guide covers both, with step-by-step fixes for the most common faults and clear guidance on when a repair goes beyond DIY.
How to Read Samsung Washer Error Codes
Samsung error codes pair a letter with a number — or two letters. Most codes appear in two formats depending on the model year.
- Newer models display codes like “5E” or “UE”
- Older models show the same fault as “5C” or “UC”
Both versions indicate the same problem. The letter simply changed between generations. Your display shows the code the moment a sensor threshold is crossed during a cycle.
Before troubleshooting, locate your model number — it’s printed on a sticker inside the door frame on front-load models or on the back panel of top-load machines. Knowing whether you have a WF or WA series narrows the diagnosis immediately.
Samsung Washer Error Codes: WF Front-Load Series
Front-load Samsung washers carry the longest list of error codes. These machines use more sensors than top-load models, which means more data — and more potential fault triggers. The table below covers every code you’re likely to encounter on WF series machines.
| Error Code | Meaning | Likely Cause |
|---|---|---|
| 4E / 4C | Water Supply Error | Water not entering the machine; kinked hose or clogged inlet screen |
| 5E / 5C | Drain Error | Water not draining; clogged debris filter or drain pump failure |
| UE / UB | Unbalanced Load | Clothes bunched to one side; machine not level |
| DE / DC | Door Error | Door latch or door switch malfunction; debris blocking strike plate |
| HE / HC | Heater Error | Heating element or NTC thermistor failure |
| OE / OC | Overfill Error | Pressure switch failure; inlet valve stuck open |
| LE / LC | Leakage Detected | AquaStop sensor activated; internal or external water leak |
| PC / PE | Pressure Chamber Error | Pressure sensor or air dome hose malfunction |
| SE / SC | Motor Sensor Error | Hall effect sensor failure on the drive motor |
| tE / tC | Temperature Sensor Error | NTC temperature sensor fault; open or short circuit |
| 8E / 8C | MEMS Sensor Error | Vibration sensor failure — VRT and VRT+ models only |
| U6 / Ub | Unbalanced Load Variant | Same fault as UE — load redistribution or levelling required |
| Sud / Sd | Excess Suds | Too much detergent or wrong detergent type for front-load machines |
Breakdown of Common Front-Load Samsung Washer Error Codes
4E / 4C (Water Supply Error): The machine isn’t filling with water — or is filling too slowly. Start by checking that both inlet hoses at the back are connected firmly and free of kinks. Then confirm the shut-off valves behind the machine are fully open. If those check out, the inlet screen filter inside the machine’s water inlet valve is likely clogged with sediment. Remove the hose, pull out the small mesh screen, rinse it under running water, and reinstall.
DE / DC (Door Error): The door isn’t latching, or the latch sensor isn’t registering a closed door. Inspect the door strike — the plastic tab on the door that inserts into the latch housing on the tub. A broken or misaligned strike is the most common cause. Also check for clothing caught in the door seal that’s preventing a full close.
HE / HC (Heater Error): The wash heater or its NTC thermistor has failed. Your machine won’t heat water for warm or hot cycles, and on some WF models it will halt mid-cycle entirely. Testing the heater element with a multimeter confirms whether it’s open-circuit. This repair requires component replacement — not a DIY task for most homeowners.
LE / LC (Leakage Detected): Samsung’s AquaStop system uses a float switch in the base pan. When water reaches that switch — from a leaking door gasket, a cracked drain hose, or a failing pump seal — the machine locks out and displays LE. Unplug the machine before inspecting. Do not restart it until the source of the leak is identified and repaired.
Samsung Washer Error Codes: WA Top-Load Series
Top-load Samsung washers are mechanically simpler than front-load models. Fewer sensors mean fewer error codes — and generally more straightforward diagnosis.
| Error Code | Meaning | Likely Cause |
|---|---|---|
| 4E | Water Supply Error | Inlet valve fault; low water pressure at the tap |
| 5E | Drain Error | Clogged drain hose; drain pump failure |
| UE | Unbalanced Load | Uneven load distribution or machine not sitting level |
| dC | Lid Error | Lid switch malfunction; lid not closing fully |
| bE2 | Button Error | Control panel button stuck or shorted |
The Most Common Samsung Washer Error Code: 5E Drain Fault
The 5E error — shown as 5C on older machines — is the fault we repair most often on Samsung washers across York Region and the GTA. Water isn’t draining, which stops the cycle and leaves a drum full of wet laundry. The cause is either a clogged debris filter or a failed drain pump.
Step-by-Step: Clearing a 5E Error on a Front-Load Samsung Washer
Step 1: Stop the cycle and unplug the machine from the wall. Do not open the door immediately — standing water may be inside the drum.
Step 2: Locate the debris filter access panel. On WF series front-load washers, it sits at the bottom right corner of the front panel. On some models it’s behind a small rectangular cover; on others, a full kick panel snaps off.
Step 3: Place a shallow dish or folded towel directly below the panel. A small drain hose is usually coiled inside — pull out the plug to release residual water before opening the filter itself.
Step 4: Turn the filter cap counterclockwise using a coin if needed. Pull it straight out. Expect more water to follow.
Step 5: Inspect the filter for lint, hair, coins, buttons, or other debris. Rinse it under running water until clean. Use a flashlight to check inside the filter housing for any debris left behind.
Step 6: Reinsert the filter and turn clockwise until snug. Do not overtighten — the housing is plastic and cracks easily. Plug the drain hose back in and press the access panel closed.
Step 7: Plug the machine back in and run a Rinse + Spin cycle. If the 5E error clears, you’re done. If it returns, the drain pump has failed — that requires a parts replacement by a technician.
Cleaning the debris filter resolves the 5E fault the majority of the time. If the pump is the problem, the repair involves accessing it through the front panel, disconnecting the motor harness, and swapping in a new pump assembly — not a safe DIY repair.
Samsung VRT and VRT+ Error Code 8E
Samsung’s VRT (Vibration Reduction Technology) and VRT+ systems use a MEMS (Micro-Electro-Mechanical Systems) sensor to monitor drum vibration during the spin cycle. When that sensor fails, the machine displays an 8E or 8C error and will either refuse to spin or spin erratically.
This fault affects specific WF series models with VRT or VRT+ designation — for example, the WF45R6100AW and similar mid-range front-loaders. The sensor sits near the drive motor and connects to the main control board via a dedicated harness. Replacement requires disassembly of the lower cabinet — a job for a technician.
Samsung Washer Error Codes: DIY Fixes vs. When to Call a Technician
Repairs You Can Handle Yourself
- Sud / Sd (Excess Suds): Run a Rinse + Spin cycle with no detergent. Going forward, switch to an HE-rated low-suds formula. Front-load machines need far less detergent than the packaging suggests — typically one tablespoon per load.
- UE / UB / U6 (Unbalanced Load): Pause the cycle, open the door, and redistribute the laundry evenly around the drum. Restart. If the error keeps returning, check that the machine is level — place a spirit level on top and adjust the levelling feet at the base until it reads flat in both directions.
- 5E — Clogged Filter: Clean the debris filter using the steps above. This resolves most 5E faults.
- 4E — Inlet Supply: Check the hoses for kinks and confirm the shut-off valves are open. Remove and rinse the inlet screen filters inside the water inlet valve connections.
Samsung Washer Error Codes That Require a Technician
- 5E — Drain Pump Failure: If cleaning the filter doesn’t clear the error, the pump motor needs replacement.
- HE / HC (Heater Error): We test and replace the wash heater element and NTC thermistor. Parts vary by model but are widely available for WF series machines.
- LE / LC (Leakage): We identify the leak source — door gasket, hose, pump seal, or tub bearing — and repair it before the AquaStop damage compounds.
- SE / SC (Motor Hall Sensor): The Hall effect sensor on the drive motor requires disassembly and component-level testing before replacement.
- OE / OC (Overfill): A stuck-open inlet valve or failed pressure switch can cause the tub to overflow. We replace the faulty component and check for water damage to the control board.
- 8E / 8C (MEMS Sensor): Sensor replacement on VRT models requires lower cabinet access — we bring the correct replacement part for your model number.
- tE / tC (Temperature Sensor): We test the NTC sensor resistance and replace it if out of specification. A short-circuit tE fault can sometimes also point to control board damage.

Frequently Asked Questions — Samsung Washer Error Codes
How do I reset my Samsung washer to clear an error code?
Unplug the machine from the wall outlet and leave it unplugged for 60 seconds. Plug it back in and restart the cycle. This clears temporary sensor faults. If the code reappears within the same cycle or on the next wash, the underlying problem still exists and needs to be addressed — a reset doesn’t fix a failed component.
My Samsung washer shows “5E” but the filter is clean. What’s next?
If the debris filter is clean and the 5E error persists, the drain pump motor has likely failed. You can confirm this by listening during the drain phase — a working pump makes an audible hum. No sound at all usually means the pump motor is seized or electrically open. Pump replacement on WF series machines runs roughly 45–60 minutes of labour and requires a new pump assembly matched to your model number.
What does “Sud” mean on a Samsung washer, and is it serious?
Sud (or Sd) means the machine detected too many suds — usually from using regular detergent instead of an HE-rated formula, or simply using too much of it. The machine pauses the cycle and attempts to reduce suds on its own before continuing. It is not a mechanical fault. Switch to HE detergent and reduce the amount per load. If Sud appears even with the correct detergent, the pressure sensor may be misreading foam levels — that warrants a technician check.
The “UE” code keeps returning even after I redistribute the load. What’s wrong?
Persistent UE errors after load redistribution usually point to one of two things: the machine isn’t sitting level on the floor, or the suspension rods (front-load) or suspension springs (top-load) are worn out. On WF front-load washers, four suspension rods support the drum — when one weakens, the drum tilts and triggers UE repeatedly regardless of load balance. We replace suspension rods in matched sets of four.
