Samsung Washing Machine 3E error code

This code means different things by model: on some washers it's a motor error (the machine detects a problem with the drive motor), and on others it's a voltage error (irregular power supply to the washer).

Also shown as: 3E1, 3E2, 3E3, 3E4, 3C, bE, E3

Quick answer: Samsung washing machine error code 3E: motor fault or irregular power supply — check manual. The most common cause is motor fault or drive-motor sensor issue (motor variant). Try this first — power cycle the washer. If that does not clear it, fix the power setup (voltage variant).

What causes the 3E error?

  • Motor fault or drive-motor sensor issue (motor variant)
  • Power interruption: outage, unplugging, or tripped breaker (voltage variant)
  • Washer on a shared circuit or extension cord causing irregular current
  • Wrong supply voltage for the model
  • Control-board or motor wiring fault

How to fix Samsung 3E — step by step

Work through these in order, from simplest and safest first. Stop as soon as the code clears.

  1. Power cycle the washer
    Turn the washer off, unplug it, and wait 2–3 minutes. Restore power and restart the cycle. This clears the code for both the motor and voltage variants if it was a one-off glitch.
    Safety warning: Unplug before any inspection; do not open the machine's panels yourself.
  2. Fix the power setup (voltage variant)
    Plug the washer directly into a wall outlet on its own dedicated circuit — never use an extension cord. Check your breaker panel for a tripped breaker and reset it if needed.
    Safety warning: Do not attempt electrical panel work beyond resetting a clearly labeled breaker; call an electrician if wiring looks damaged.
  3. Confirm which variant your model uses
    Check your user manual to see whether 3E on your model is a motor error or a voltage error, then follow the matching guidance above.
  4. Request service if it returns
    If the code comes back after a proper power cycle (and correct power setup for the voltage variant), the motor, inverter, or control board needs a technician.

When to call a technician

Stop and call a qualified technician if any of these apply:
  • Code returns after power cycling with correct power setup
  • Burning smell, sparks, or unusual noises from the motor area
  • Anything involving the motor, inverter board, or internal wiring — all need panel access by a professional

Frequently asked questions

Is 3E a motor error or a voltage error?

Both exist. On some models 3E (with 3C, 3E1–3E4) is a motor error; on others it sits in the voltage-error group with 9C1, 9C2, PF, and UC. Your user manual tells you which.

Can a power outage cause 3E?

Yes — if power was cut before the washer shut itself down, a voltage-type 3E or the related PF code can appear. Restarting after stable power returns usually clears it.

Why does Samsung say not to use an extension cord?

Extension cords can deliver irregular current to the washer, triggering voltage errors and potentially stressing the electronics.
