The Samsung washing machine PF error indicates a “Power Failure” disruption that halted the appliance during a wash or rinse cycle. While this code often appears after a neighborhood power outage, it can also signal internal electrical issues or voltage irregularities within your home’s circuit.
Understanding the root cause of this error is critical to preventing cycle interruption and protecting your appliance’s sensitive electronics. This guide covers professional troubleshooting steps, from basic reset procedures to inspecting the control board and electrical supply.

What Does the Samsung Washing Machine PF Error Mean?
Technically, the Samsung washing machine PF error is not a malfunction code but a notification. It informs the user that the power supply to the machine was cut off while a program was active. When power is restored, the washer displays “PF” to alert you that the cycle did not finish.
Common triggers include:
- Power surge or blackout in the local grid.
- A tripped circuit breaker or blown fuse.
- Loose connection at the wall outlet.
- Voltage drops caused by high-wattage appliances sharing the same circuit.
- Faulty power cords or use of extension cords (which Samsung advises against).
Immediate Troubleshooting Steps
If you see the PF code, do not panic. In most cases, the washer simply needs to be reset. Follow these steps to clear the error and resume laundry.

1. The Basic Reset Procedure
The simplest fix is to acknowledge the interruption and restart the machine.
- Press the Start/Pause button or the Power button to clear the code from the display.
- If the washer was in the middle of a cycle, run a “Rinse + Spin” cycle to drain any standing water and remove detergent residue.
- Restart the original load from the beginning.
2. Inspect the Power Cord and Wall Outlet
Electrical consistency is vital for modern appliances.
- Check the Plug: Ensure the power cord is firmly seated in the wall outlet. A loose plug can cause momentary power loss during the spin cycle when the machine vibrates.
- Avoid Extension Cords: Samsung washers require a dedicated outlet. Extension cords often cannot handle the amperage, leading to voltage fluctuation that triggers the PF error.
- GFCI Outlet Check: If your laundry room uses a GFCI outlet (Ground Fault Circuit Interrupter), check if the “Reset” button has popped out. High humidity or a minor surge can trip these outlets specifically.
3. Check the Circuit Breaker
If the washer won’t turn on or the PF error persists, visit your home’s electrical panel.
- Locate the breaker labeled “Laundry” or “Washer.”
- If the circuit breaker is in the “OFF” or middle “Tripped” position, flip it completely off, then back to “ON.”
- Note: If the breaker trips immediately after starting the washer, do not force it. This indicates a serious electrical short or a failing component that requires appliance repair.
Advanced Troubleshooting: Voltage and Internal Components
If the Samsung washing machine PF error appears frequently without an obvious power outage, the issue may lie within the machine’s internal power management.
Voltage Fluctuation and Surges
Modern Samsung washers have sensitive sensors that detect irregularities in current. If your home experiences frequent voltage fluctuation, the main PCB (Printed Circuit Board) may cut power to protect itself.
- Solution: Monitor other lights in the room. If they flicker when the washer motor starts, your home’s wiring may need inspection by an electrician.
Control Board and Wiring Issues
In rare cases, the error stems from the washer’s control board or internal wiring harness.
- Loose Connections: Vibrations over years of use can loosen the wire harnesses connecting the power cord to the main noise filter or PCB.
- Board Failure: A damaged control board may fail to maintain a steady power logic, falsely registering a power loss.
- Diagnosis: This level of troubleshooting involves opening the washer casing. Unless you are trained in appliance repair, it is recommended to contact a certified technician to avoid voiding your warranty or risking electrical shock.
Prevention Tips
To avoid seeing the Samsung washing machine PF error in the future:
- Install a Surge Protector: Use a high-quality appliance-rated surge protector (if permitted by the manual) or a whole-home surge protector to guard against grid spikes.
- Balance Loads: excessively heavy or unbalanced loads can strain the motor, drawing more amps and potentially tripping sensitive breakers.
- Dedicated Circuit: Ensure your washing machine is the only major appliance on its electrical circuit. Sharing a line with a dryer, heater, or refrigerator usually leads to power instability.
By systematically checking the power source, resetting the breaker, and ensuring stable voltage, you can resolve the PF error and keep your Samsung washer running efficiently.

Frequently Asked Questions
What does the PF error code specifically mean?
PF stands for “Power Failure.” It is not necessarily a malfunction code but a notification that the power supply was interrupted while a wash or rinse cycle was active. It alerts you that the machine stopped unexpectedly and the cycle did not finish.
How do I clear the PF error and resume my laundry?
To clear the code, press the Start/Pause or Power button. If the machine stopped mid-cycle, it is best to run a “Rinse + Spin” cycle to clear out any standing water or detergent residue before restarting your original wash load from the beginning.

Why does the PF error appear if there wasn’t a neighborhood power outage?
The error can be triggered by localized electrical issues, such as a loose power plug, a tripped circuit breaker, or a blown fuse. It also occurs if the washer is plugged into an extension cord or if high-wattage appliances sharing the same circuit cause a sudden drop in voltage.
Can I use a surge protector to prevent this error?
Yes, using a high-quality, appliance-rated surge protector or a whole-home surge protection system can help guard the washer’s sensitive electronics against grid spikes. However, you should always check your user manual first to ensure a surge protector is permitted for your specific model.
When should I call a professional for a PF error?
You should seek professional appliance repair if the PF error occurs frequently despite a stable power supply, or if your circuit breaker trips immediately every time the washer starts. These symptoms often point to a faulty main control board or internal wiring issues that require expert diagnosis.
