What Does Error Code 3E3 Mean on a Samsung Washing Machine?
Power off the machine at the wall, leave it unplugged for 10 minutes to fully reset the motor control circuit, then restart a short cycle to see whether the error clears (takes about 10 minutes).
Fault description
When your Samsung washing machine displays error code 3E3, it has detected a problem with the motor's communication or rotation sensor circuit. The hall sensor is a small component attached to the drive motor that sends speed and position data back to the main control board. When that signal is absent, erratic, or outside the expected range, the machine logs 3E3 and stops the cycle to protect the motor from damage.
In practice, you may notice the drum failing to spin up to speed, stopping mid-cycle, or the machine refusing to start a spin phase at all. The display will show 3E3 and the programme will pause. This fault affects a range of Samsung front-loader models including the B-series, F-series, J-series, and the FlexWash WV60M9900AV, so the guidance below applies broadly across those machines.
Causes
- Faulty or failed hall sensor — The hall sensor monitors motor rotation and feeds that data to the PCB. If the sensor itself has failed or drifted out of calibration, the board receives no usable signal and triggers 3E3.
- Loose or damaged wiring to the motor or hall sensor — Vibration during spin cycles can work connectors loose over time. A partially disconnected or chafed wire between the motor, hall sensor, and control board will interrupt the signal and produce this error.
- Worn motor carbon brushes — On brush-type motors, the carbon brushes transfer current to the motor armature. When they wear down below a usable length, motor rotation becomes inconsistent, which the hall sensor reports as a fault.
- Drive motor failure — If the motor windings are damaged or the motor has seized, it will not rotate correctly regardless of sensor condition. The hall sensor will then report abnormal or absent rotation data.
- Main PCB (control board) failure — The PCB processes the hall sensor signal and controls motor output. A fault on the board — such as a damaged motor driver component — can cause it to misread or fail to send correct signals, producing a false 3E3 code.
Step-by-Step Fix
- 1
Reset the machine with a full power cycle
Switch the machine off at the wall socket and unplug it completely. Leave it disconnected for at least 10 minutes to allow the motor control circuit to discharge and reset. Plug back in, select a short cotton cycle, and observe whether 3E3 returns. A one-off software glitch will clear at this stage.
- 2
Check the drum for obstructions
Before opening any panels, try turning the drum by hand through the door. It should rotate smoothly with only light resistance. If it feels stiff, grinds, or will not turn, something may be jamming the drum or the motor bearing has failed — both of which can trigger motor fault codes.
- 3
Inspect the wiring harness connections at the motor and hall sensor
Disconnect the machine from the mains, then remove the rear panel (usually held by two or three screws along the top edge). Locate the drive motor at the base of the machine and trace the wiring harness to the hall sensor connector and the motor connector. Press each connector firmly until it clicks, and look for any wires that are pinched, burnt, or have pulled out of their terminals. Reconnect the panel and retest.
- 4
Examine the carbon brushes for wear
With the rear panel removed, the carbon brush holders are visible on either side of the motor body. Unclip or unscrew each holder and slide out the brush. A healthy brush is typically 15–18 mm long; if either brush is worn down to 5 mm or less, or shows uneven wear, replace both brushes as a pair. New brushes are an inexpensive and straightforward fix on these models.
- 5
Test and replace the hall sensor
The hall sensor is a small plastic component clipped to the motor casing, connected by a three-wire harness. Visually inspect it for cracks or heat damage. If you have a multimeter, check for the correct supply voltage (typically 5 V DC) at the sensor connector with the machine powered on. If the sensor is damaged or giving no output signal, replace it — it is a low-cost part and the most common cause of 3E3 on these models.
- 6
Check the drive motor itself
If brushes and sensor are both in good condition, use a multimeter to check the motor windings for continuity. Set the meter to resistance mode and test across the motor terminals according to the resistance values in your model's service data (typically 4–8 ohms for the main winding). An open circuit or very high resistance reading indicates a failed motor that will need replacement.
- 7
Consider the main control board as a last resort
If all wiring, the hall sensor, brushes, and motor test as good, the fault may lie with the PCB's motor driver circuit. PCB faults are difficult to diagnose without specialist equipment. At this point, note all the steps you have already completed and contact a service technician, as replacing a PCB without confirming it is faulty is an expensive mistake.

When to call a service technician
Call a service technician if the error code returns immediately after you have replaced the hall sensor and confirmed all wiring connections are secure. This pattern suggests the motor itself has failed or the PCB's motor driver circuit is damaged — both repairs require specialist diagnostic tools and, in the case of the PCB, careful component-level testing to avoid unnecessary parts costs.
You should also seek professional help if you find burnt or melted wiring near the motor, if the drum is completely seized and will not turn by hand, or if the machine trips your household circuit breaker when it attempts to start. These symptoms point to an electrical fault that goes beyond straightforward component replacement.

Frequently Asked Questions
Can I still use my Samsung washing machine while it shows error 3E3?
No — when 3E3 is active the machine has halted the cycle to protect the motor from damage caused by running without correct sensor feedback. Attempting to force the machine to run in this state risks worsening the fault. Diagnose and resolve the error before using the machine again.
How long do Samsung washing machine carbon brushes typically last?
On average, carbon brushes last between 5 and 10 years depending on how heavily the machine is used and whether it is regularly overloaded. Machines used daily for large households will wear brushes faster. Replacing them is a straightforward DIY job and is worth doing as routine maintenance once the machine is over five years old.
Is error code 3E3 the same as 3E, 3E1, or 3E2 on Samsung machines?
They are related but distinct codes. All 3E variants point to motor circuit problems, but 3E3 specifically indicates a communication or rotation sensor circuit fault rather than a general motor overload (3E) or a different motor sub-circuit issue. The diagnostic steps overlap, but the hall sensor and its wiring are the primary focus for 3E3.
How much does it typically cost to repair a Samsung 3E3 error?
If the fix is a new hall sensor or a set of carbon brushes, parts typically cost between £10 and £35 depending on the model, making it one of the more affordable washing machine repairs. A replacement drive motor is more expensive, usually £60–£120 for the part alone. A service technician call-out will add labour costs on top of any parts.
Will a factory reset on the control panel clear error code 3E3 permanently?
A control panel reset or power cycle may clear the code temporarily if the fault was caused by a one-off signal glitch, but it will not fix an underlying hardware problem. If the hall sensor, brushes, or motor are worn or faulty, the code will return as soon as the machine attempts to spin again. Always investigate the physical cause rather than relying on resets alone.
