How to Reset a Samsung Washing Machine
Most Samsung washer error codes clear with a power reset. The code returns immediately if the underlying fault is still present.
Reset Steps
- 1
Press Power to turn the washer off.
- 2
Unplug the washer (or switch off its breaker) and wait at least 60 seconds — this lets the control board fully discharge.
- 3
Plug it back in, power on, and start a short cycle (Rinse + Spin) to confirm the code is gone.
- 4
If the same code returns within the first cycle, the fault is real — look up the code and work through its fix steps.
💡 Good to know: There is no hidden 'master reset' beyond a power cycle on Samsung washers. Codes like UE (unbalance) also clear by simply redistributing the load and pressing Start.
If the Code Comes Back
A code that returns after a reset means the underlying fault is still present. Look up your exact code for its causes and step-by-step fix:
4C Water supply not detected UE Unbalanced load detected OE Drain failure — water not draining LE Motor locked — drum cannot rotate DE Door not properly closed or door lock failure HE Water heater error — water not heating to target temperature SUD Excessive suds detected tE Temperature sensor (thermistor) fault
Frequently Asked Questions
How do I see the last error code on a Samsung washer? +
Active codes show automatically on the display. For fault history, run the self-check in the SmartThings app — most 2018-and-newer Samsung washers support it.
Does unplugging a Samsung washer clear error codes? +
Yes. A 60-second power cycle clears the displayed code. If the fault is still present, the code reappears as soon as the washer retries the failed operation.
