A 9C1 or 9C2 display moves troubleshooting away from hoses and loads and toward the power source. External checks are appropriate; live voltage measurements and internal board work are not.
Samsung washer 9C1 9C2 code: Samsung groups 9C1, 9C2, PF and several related displays under voltage errors. The code indicates that the electrical supply or the washer’s interpretation of it is outside the expected condition.
What this display is telling you
Recognize a Samsung voltage error and evaluate the external power supply safely.
A safe response, in order
- Turn the washer off and unplug it from a dry, undamaged receptacle.
- Check whether the home experienced an outage, flicker, surge, or breaker trip.
- Inspect the cord, plug, and receptacle visually for heat, looseness, discoloration, or damage.
- Do not use an extension cord, adapter, or power strip. Connect only as the installation instructions specify.
- Restore power once when the supply appears stable. Stop if the code returns or the breaker trips.
What can sit behind the code
- Supply voltage outside the washer’s accepted range.
- A power interruption recorded as PF on applicable models.
- A damaged connection, incorrect circuit arrangement, or internal power/control fault.
Important distinctions
Samsung notes that code meaning can be model dependent; the manual is especially important when 3E appears, because it can indicate motor or voltage conditions.
Do not keep resetting a breaker. Repeated tripping signals a fault that needs a qualified electrical or appliance diagnosis.
A power cycle is a controlled retry, not proof that the underlying supply problem is gone.
If the display clears after the external condition is corrected and does not return, monitor the next full cycle. A code that comes back at the same stage is stronger evidence of a recurring fault than a single interrupted cycle. Stop immediately when the observation includes uncontrolled water, abnormal heat, an electrical smell, a breaker trip, or violent movement.
Check the exact model before going further
The exact alias set and required electrical supply are printed in the model installation instructions. Do not generalize dryer voltage guidance to a washer.
The point to stop troubleshooting
Use a qualified electrician when the receptacle or circuit is suspect, and Samsung service when the supply is confirmed but the washer continues to report a voltage error.
Have the appliance model information ready. A short note describing what entered, moved, drained, heated, or locked immediately before the code is more useful than a guessed component name.

Frequently asked questions
Can I measure the outlet voltage myself?
Live electrical testing should be done only by a qualified person with the correct equipment.
Is PF always part of the same code on every Samsung washer?
No. Samsung code usage varies; verify the exact model manual.
