Samsung Washer Error Code 9C1 — Voltage/Power Error
What this means
The 9C1 error code indicates the washer is receiving inconsistent or insufficient voltage from the power outlet. This can be caused by a power surge, brownout, loose electrical connection, or the washer sharing a circuit with other high-draw appliances. Using an extension cord with the washer can also cause this error due to voltage drop.
Alternate codes: 9C, PF, 2E, 9E1
Step-by-step fix
4 stepsReset the washer
Unplug the washer for 5 minutes and plug it back in. If the error was caused by a temporary power fluctuation, it should clear.
Wait for the display to come back on before starting a cycle.
Check the power outlet
Plug the washer directly into a wall outlet (not an extension cord or power strip). Test the outlet voltage with a multimeter — it should read between 110V and 120V for US homes.
An outlet reading below 105V or above 130V indicates a house wiring issue.
Use a dedicated circuit
Ensure the washer is on its own dedicated circuit and not sharing with other high-draw appliances like a dryer, space heater, or microwave.
When another large appliance on the same circuit turns on, it can cause a momentary voltage drop.
Inspect the power cord
Check the washer's power cord for damage, loose prongs, or a worn plug. A loose connection at the outlet can cause voltage fluctuations.
If the plug wiggles in the outlet, the outlet may need replacement.
When to call a professional
If the outlet voltage is correct, the washer is on a dedicated circuit, and the error persists, the washer's power supply board or main control board may be faulty. Call an appliance technician. If the house wiring is suspect, call an electrician.
