Samsung Washing Machine Error Code SE — Motor / Tachometer Error

Likely Needs a Technician Often confused with: 5E (drain error, different problem)
SE and 5E look almost identical on a Samsung display. They are different errors. SE (the letter S) is a motor error covered on this page. 5E (the number 5) is a drain error. If your washer has water sitting in the drum that won't pump out, you likely have error code 5E (drain) instead.
Quick Answer

The SE error code means your Samsung washing machine has detected a problem with the drive motor or its tachometer (speed sensor). The drum is not spinning at the expected speed, or the control board cannot read the motor's speed signal. A basic reset fixes some SE errors, but if the code persists, the tachometer, motor, or wiring likely needs professional repair.

What the SE Code Means

The Samsung washing machine error code SE is a motor or tachometer error that indicates the control board cannot properly communicate with the drive motor or read the motor's speed. The tachometer (also called a hall sensor) is a small sensor attached to the motor that reports how fast the drum is spinning. When the control board receives no signal, an erratic signal, or a speed reading that does not match what it commanded, the washer halts and displays SE.

This code can appear during any part of a wash cycle, including agitation, rinsing, or the spin phase. It is most commonly noticed during the spin cycle because that is when the motor runs at its highest speed and sensor problems become most apparent.

Critical distinction: SE (letter S) and 5E (number 5) look almost identical on Samsung's seven-segment digital displays. SE is a motor error. 5E is a drain error. The fixes are completely different. If your washer has water sitting in the drum that will not pump out, you most likely have a 5E error, not SE. Look carefully at the first character on the display.

Unlike many Samsung washer codes, SE is not typically a DIY fix. The tachometer, motor wiring, and motor itself are internal components that require disassembly and electrical testing. That said, a few safe steps are worth trying before calling a technician.

Common Causes — Most Likely First

1
Temporary control board glitch. A power fluctuation or one-time electrical hiccup caused the control board to lose the motor signal momentarily. A reset clears this. Common
2
Overloaded drum. An extremely heavy or unbalanced load can strain the motor, causing it to spin slower than expected. The control board reads this as a motor fault. Common
3
Faulty tachometer (hall sensor). The speed sensor on the motor has failed or its connection has come loose. The control board cannot read the motor speed and triggers SE. Needs a technician
4
Damaged wiring between the motor and control board. A wire in the motor harness is broken, corroded, or has a loose connector. The speed signal cannot reach the control board. Needs a technician
5
Failed drive motor. The motor itself has burned out or has an internal short. It either does not spin at all or spins erratically. Needs a technician
6
Main control board failure. The PCB that reads the motor signal has a damaged component. This is the least common cause but can happen after power surges. Needs a technician

How to Fix the SE Error — Step by Step

Unplug the washer and wait 60 seconds

Disconnect the washing machine from the power outlet. Wait a full 60 seconds. This allows the control board to fully reset and clear any temporary glitch that caused the SE code.

Reduce the load size

If the washer was running a very heavy or bulky load when the SE code appeared, remove some items. An overloaded drum can strain the motor and trigger the error. Redistribute the remaining laundry evenly around the drum.

Note: Bulky items like comforters, blankets, and rugs are common overload culprits. Try washing them on their own with nothing else in the drum.

Check for items trapped between the drum and the tub

Small items (socks, underwear, rags) can slip between the inner drum and the outer tub on some models. If the drum feels stiff or does not spin freely by hand, something may be jammed. Try rotating the drum manually. If it catches or grinds, stop and call a technician.

Plug back in and run a short cycle

Plug the washer back in and select a short or quick wash cycle with a small load. Watch and listen through the wash and spin phases. If the cycle completes normally without the SE code, the issue was a temporary glitch or overload.

If the code returns, the motor system needs professional diagnosis

If SE reappears after a reset and reduced load, the tachometer, motor wiring, motor, or control board likely has a hardware fault. These are internal electrical components that require a technician to test and replace safely. Do not attempt to disassemble the washer.

When to Call a Technician

SE errors have limited DIY options. Book a professional Samsung appliance repair if:

  • The SE code returns after a power reset and with a reduced or empty load
  • The drum does not spin at all, or spins briefly and stops
  • You hear a grinding, scraping, or buzzing noise from the motor area during the spin cycle
  • You smell a burning or electrical odor coming from the washer
  • The washer trips the circuit breaker when it tries to spin

How Promix Repairs Samsung Washing Machine SE Errors

When a Promix Appliance Repair technician arrives for a Samsung washing machine SE error, the first step is confirming the code is SE (motor) and not 5E (drain), since many homeowners mix them up. The technician then runs a diagnostic test mode to read the motor speed signal directly. Using a multimeter, the technician tests the tachometer sensor for proper resistance, checks the wiring harness for continuity, and inspects the motor for signs of failure.

The most common repair for a persistent SE code is replacing the tachometer sensor or re-seating a loose motor connector. If the drive motor itself has failed, the technician replaces it. Promix carries common Samsung washer and dryer repair parts on every service vehicle, so many SE repairs are completed in a single visit. All repairs include a warranty on parts and labor. A service call fee applies and is credited toward the repair if you choose to proceed. Call (781) 666-9565 to schedule.

How to Prevent Error Code SE From Coming Back

Do not overload the washer. Follow the load capacity guidelines in your owner's manual. Overloading strains the motor and is the most common trigger for one-time SE errors.
Wash bulky items separately. Comforters, sleeping bags, and heavy rugs should be washed alone. Mixing them with regular clothes creates unbalanced loads that tax the motor.
Use a surge protector. Power surges can damage the control board and motor electronics. A surge protector on the washer's outlet adds a layer of protection.
Keep the washer level. An unlevel washer causes excessive vibration during spin cycles, which accelerates wear on the motor and its sensor over time.

Frequently Asked Questions

Can I keep using my Samsung washing machine with error code SE?

No. The SE code means the washer has detected a motor or speed sensor fault, and the machine will not complete a cycle. Running the washer repeatedly with an SE error can cause further damage to the motor or control board. Try the reset steps first, and if the code returns, stop using the washer until a technician diagnoses the issue.

Will resetting my Samsung washing machine clear error code SE?

Unplugging the washer for 60 seconds and plugging it back in will clear the code from the display. If the cause was a temporary glitch or a one-time overload, the code may not return. However, if the tachometer, motor, or wiring has a hardware fault, the code will reappear as soon as the washer tries to spin.

How long does it take to fix Samsung error code SE?

If a reset resolves the error, it takes about 10 minutes. If a technician needs to replace the tachometer sensor or re-seat a motor connector, the repair typically takes 30 to 60 minutes. A full drive motor replacement may take up to 90 minutes depending on the washer model and access.

Is Samsung error code SE covered under warranty?

If your Samsung washer is still within the manufacturer's warranty period (typically one year for parts and labor), a failed tachometer or motor may be covered. Some Samsung models carry extended warranties on the motor (up to 10 years on select inverter motors). Check your warranty documentation or contact Samsung directly to verify coverage for your specific model.

What is the difference between Samsung error codes SE and 5E?

SE (the letter S) is a motor or tachometer error. It means the washer's drum is not spinning correctly. 5E (the number 5) is a drain error. It means the washer cannot pump water out of the drum. They look nearly identical on Samsung's digital display, which is why they are so frequently confused. If water is trapped in the drum, you have a 5E. If the drum is not spinning but water drains fine, you have an SE.

Does Samsung error code SE mean I need a new washing machine?

Not usually. The SE code most often points to a failed tachometer sensor, which is a relatively small and affordable part. Even a full motor replacement is a viable repair for most Samsung washers that are less than 8 to 10 years old. A qualified technician can confirm whether the repair cost makes sense for your specific machine.
