Samsung Washing Machine Error Code 9E1
Low voltage detected — power supply problem
The washer is detecting abnormal input voltage. 9E1 typically means voltage is too low; 9E2 means too high. The washer shuts down to protect electronics from damage.
What Does Error Code 9E1 Mean on a Samsung Washing Machine?
Low voltage detected — power supply problem.
The washer is detecting abnormal input voltage. 9E1 typically means voltage is too low; 9E2 means too high. The washer shuts down to protect electronics from damage.
What Causes Error Code 9E1?
Here are the most common causes in order of frequency. Start with the most likely cause before moving to the next:
- 1 Low household voltage — shared circuit under heavy load 50% of cases
- 2 Extension cord or undersized outlet wiring 30% of cases
- 3 Voltage fluctuation from utility 15% of cases
- 4 Internal power board fault 5% of cases
How to Fix Samsung Washing Machine Error Code 9E1
- 1
Check the outlet voltage
Use a multimeter on the outlet. Samsung washers require 120V (±10%), typically 108–132V. Below 100V during spin cycle is common if sharing a circuit.
🔩 Multimeter or outlet voltage tester - 2
Move to a dedicated circuit
Washers should be on a dedicated 20A circuit. Sharing with other appliances causes voltage sag during spin.
- 3
Check power board
If voltage is good but error persists, the internal power monitoring circuit has failed.
🔩 Samsung power board ($80–$200)
How to Reset Error Code 9E1
Restore proper voltage and unplug for 5 minutes. Restart on a dedicated circuit.
Note: If the error returns after resetting, the underlying issue has not been resolved. Work through the fix steps above.
When to Call a Professional
Persistent 9E1 on a known-good circuit indicates an internal power regulation fault requiring professional service.
