What Does Error 9 E1 Mean?

The Samsung Washing Machine error 9 E1 indicates an issue with the door lock mechanism, often triggered by unstable or incorrect mains voltage supply. This error may cause the washer to stop functioning, failing to start or complete its cycles due to detected voltage irregularities. Fluctuations in power can lead to this electronic control error, impacting the machine's performance.

Common Symptoms:

  • Washer stops and displays 9E1 code
  • Issue occurs shortly after power-on or during operation when voltage fluctuates
  • Machine fails to start or continue cycle due to detected voltage irregularities

Possible Causes

  • Unstable or incorrect mains voltage supply (overvoltage or undervoltage) (medium)

How to Fix Error 9 E1

DIY Fix Check basic power supply and reset

  1. Turn off and unplug the washing machine.
  2. Ensure the outlet used is properly grounded and not overloaded with adapters or extension cords.
  3. Plug the washer directly into a known stable outlet.
  4. Restart the washer and see if the 9E1 code clears.

Technician Only Measure and stabilize voltage, inspect control electronics

  1. Use a multimeter to measure the mains voltage at the outlet under load.
  2. Verify that the voltage is within acceptable range for the washer.
  3. Inspect power supply wiring to the washer for loose connections.
  4. Check the washer’s PCB and power input circuitry for damage from voltage spikes.
  5. Replace or repair damaged power components as needed.

Parts needed: Multimeter (for diagnostic), Voltage stabilizer or surge protector (if needed), PCB/power module (if damaged)

🛑 When to Call a Pro:
  • If the error persists after checking and stabilizing power supply
  • If there are signs of electrical damage (burnt smell, smoke, visible PCB damage)
  • If you are not comfortable or equipped to safely measure electrical voltage
