What Does Error Code E Mean on a Samsung Washing Machine?
Power the machine off at the wall socket, wait 2 minutes, then switch it back on and run a short cycle to clear the fault — this resolves the majority of generic E error cases caused by a temporary control board glitch (takes about 5 minutes).
Fault description
Error code E is Samsung's catch-all fault code, displayed when the control board detects an electronic or sensor problem it cannot assign to a more specific category. Unlike targeted codes such as 4C or 5C, the E code doesn't point directly to one component — it signals that something in the machine's electronic communication or sensing system has gone wrong, but the board lacks enough information to be more precise.
When this code appears, the washing machine will typically pause mid-cycle or refuse to start, and the display will show the letter E on its own. The drum may stop moving, and the machine will not continue until the fault is cleared. In many cases, the cause is a temporary software glitch rather than a failed component, which is why a simple reset resolves the problem for a large proportion of users.
If the code returns after a reset, it's worth working through the checks below systematically before assuming a part has failed. Models affected include the B1253, F1045, J1466, FlexWash WV60M9900AV, and several others across Samsung's older and mid-range washing machine range.
Causes
- Temporary control board glitch — A brief power fluctuation or software hiccup can cause the control board to log an unclassified fault and display the E code. This is the most common cause and is usually cleared by a full power reset.
- Faulty or loose wiring harness connection — Vibration from normal use can loosen the connectors between the control board and sensors such as the thermistor, door lock, or motor. A poor connection can cause the board to receive no signal or an out-of-range reading, triggering the generic E code.
- Defective temperature sensor (thermistor) — If the thermistor fails or reads an implausible temperature, the control board may log an unclassified error rather than a specific temperature fault code. This is more common on older machines where the sensor has degraded over time.
- Door lock assembly fault — A door interlock that is slow to engage or sending an inconsistent signal can confuse the control board into logging a generic fault. The machine may appear to start but then stop and display E before the drum begins to spin.
- Main control board (PCB) failure — If the control board itself has a damaged component — such as a burnt relay or failed capacitor — it may be unable to correctly interpret sensor data and will display E as a fallback. This is less common but more likely on machines that have experienced a power surge.
- Motor or motor control module issue — A problem with the drive motor or its associated control module can produce signals the main board cannot categorise, resulting in the E code. You may notice the drum failing to rotate or making unusual noises before the code appears.
Step-by-Step Fix
- 1
Perform a full power reset
Switch the machine off using the power button, then unplug it from the wall socket. Leave it unplugged for at least 2 minutes to allow the control board's capacitors to fully discharge. Plug it back in, power it on, and run a short cotton cycle to see if the fault clears.
- 2
Check the door is fully closed and latching correctly
Open and firmly close the door, listening for a clear click from the door lock. If the door feels loose or the lock sounds weak, inspect the door catch and striker for visible damage. A door that isn't seating properly can cause the interlock to send an inconsistent signal to the control board.
- 3
Inspect the wiring harness connectors
With the machine unplugged, remove the top panel (usually secured by two screws at the rear). Locate the main wiring loom and gently press each connector firmly into its socket on the control board and any visible sensors. Look for any wires that appear pinched, burnt, or corroded. Reconnect the panel and test the machine.
- 4
Run the machine's built-in diagnostic cycle
Many Samsung washing machines have a self-diagnostic mode accessible by holding specific button combinations — refer to your model's user manual for the exact sequence. Running diagnostics may produce a more specific fault code that gives you a clearer direction for the repair.
- 5
Test the thermistor (temperature sensor)
The thermistor is usually located on the heater assembly at the rear or base of the drum. With the machine unplugged, disconnect the thermistor and use a multimeter set to resistance (Ohms) to test it — a healthy thermistor typically reads between 10kΩ and 50kΩ at room temperature depending on the model. A reading of zero or infinity indicates a failed sensor that needs replacing.
- 6
Check the door lock assembly
With the machine unplugged, use a multimeter to test the door interlock for continuity across its terminals. If the lock shows no continuity when engaged, or continuity when it should be open, the assembly is faulty and should be replaced. Door lock assemblies are a relatively inexpensive and straightforward part to swap on most Samsung models.
- 7
Inspect the main control board for visible damage
With the machine unplugged and the top or back panel removed, visually inspect the PCB for signs of burning, scorch marks, swollen capacitors, or corrosion. If you find any of these, the board will need to be replaced or the machine assessed by a service technician, as PCB faults are not safely repairable at home.

When to call a service technician
If the E code returns immediately after every reset, or if you have worked through all the steps above without finding a clear cause, it is time to contact a service technician. This is especially true if you can see burn marks or smell burning from the control board area, if the drum is not turning at all, or if the machine trips your household circuit breaker when switched on — these symptoms suggest an electrical fault that goes beyond routine DIY repair.
You should also seek professional help if your multimeter tests point to a failed motor or motor control module, as these components require careful handling and accurate diagnosis to avoid an unnecessary and costly replacement. A service technician can connect specialist diagnostic equipment to read the board's full fault log and pinpoint the problem precisely.

Frequently Asked Questions
Is error code E serious on a Samsung washing machine?
Not necessarily. In many cases, the E code is caused by a temporary software glitch and clears after a simple power reset. However, if it keeps returning, it can indicate a failing sensor, a loose wiring connection, or in more serious cases, a damaged control board. Work through the troubleshooting steps before assuming the worst.
Why does my Samsung washing machine show E and then stop mid-cycle?
The machine stops mid-cycle because the control board has detected an unclassified fault and halted operation as a safety measure. This can happen if a sensor sends an unexpected reading during the wash — for example, the thermistor reporting an implausible temperature or the door lock sending an inconsistent signal. Running the diagnostic cycle may reveal a more specific underlying code.
How do I reset a Samsung washing machine to clear the E code?
Turn the machine off using the power button and unplug it from the wall socket. Wait at least 2 minutes, then plug it back in and power it on. This allows the control board to fully reset. If the code reappears after the reset, the fault is likely hardware-related rather than a temporary glitch.
Can a power surge cause the E error code on a Samsung washing machine?
Yes. A power surge can corrupt the control board's memory or damage components on the PCB, causing it to display a generic E fault. If the code appeared after a storm or a power cut, inspect the control board for visible damage such as burn marks or swollen capacitors. Using a surge-protected extension lead can help prevent this in future.
How much does it cost to fix a Samsung washing machine showing error code E?
If the fix is a simple reset, the cost is nothing. Replacing a thermistor or door lock assembly typically costs between £15 and £50 for the part, and these are manageable DIY repairs for most homeowners. A new main control board is more expensive, usually £60–£150 for the part alone, and fitting it professionally will add labour costs on top.
