What the PF error code actually means

The PF code means your Samsung washer detected a problem with the electrical power coming into the machine, either the voltage was too low, too high, or briefly dropped during a cycle. This can happen if the washer is plugged into an extension cord or power strip instead of directly into a wall outlet. In less common cases, a faulty control board inside the washer can also cause this error to appear.

Questions people ask about PF

What does PF mean on a Samsung washer?
PF stands for a power fault and indicates that the washer detected an under-voltage or over-voltage condition in its electrical supply. It can also trigger when a plug receptacle or extension cord causes a momentary voltage drop of up to 10 volts. In some cases, a faulty main PBA can generate this code even when the supply voltage is normal.
Will resetting my Samsung washer clear the PF code?
A reset may temporarily clear the PF code, but if the underlying cause is not resolved, the code will return. Before resetting, address any power supply issues such as removing extension cords or fixing a faulty outlet. If the problem is a failing main PBA, resetting will not provide a lasting fix.
How much does it cost to fix a Samsung washer PF error?
If the fix is simply removing an extension cord or replacing a faulty wall outlet, costs are minimal, typically in the range of $10 to $50 for outlet parts if needed. If the main PBA is the cause, board replacement is more involved and repair costs including parts and labor generally range from $150 to $400 depending on the specific model and service provider.
How do I fix the PF error on my Samsung washer?
Start by checking that the washer is plugged directly into a wall outlet and not through an extension cord or power strip. Use a multimeter to verify the outlet is supplying correct voltage. If the power supply is confirmed good and the error persists, the main PBA may need to be inspected and potentially replaced.
Is it safe to keep using my Samsung washer when PF is displayed?
It is not advisable to continue running the washer while the PF code is active. The code indicates the machine is receiving power outside its safe operating range, which can stress or damage the control board and motor components over time. Resolve the power supply issue before resuming normal use.
