Whirlpool Dryer PF Error Code: What It Means and How to Fix It
Updated · from manufacturer service documentation
PF on a Whirlpool dryer means Power Failure — the dryer lost power while it was running a cycle. This isn't a hardware fault; it's simply the dryer reporting that its power was interrupted mid-cycle. You choose whether to continue the cycle or clear the display.
What Causes the PF Code
| Cause | Likelihood | DIY difficulty | Related part |
|---|---|---|---|
| Momentary power outage or interruption while the dryer was running | Most common | Not applicable — informational code | — |
| Low L2 line voltage (related code L2, below 50V at the CCU) | Less common | Moderate — see F4E4 procedure | CCU |
How to Fix It, Step by Step
-
Decide whether to continue or clear the cycle
Per the service documentation, press START to continue the cycle from where it left off, or press POWER to clear the display and start fresh.
-
If you also see an L2 code, check the line voltage
L2 means low L2 voltage (less than 50V) was detected at the CCU — a related but distinct condition, addressed by the same procedure as Fault/Error Code F4E4 ("L2 Line Voltage Error").
-
Check the fuse or breaker first
The documented F4E4 procedure starts here: see whether a household fuse has blown or a circuit breaker has tripped. A partially lost supply is exactly what produces a low-voltage reading at the control board rather than a clean shutdown.
-
Confirm the power cord is properly installed
Make sure the cord is fully seated at the dryer and plugged into the outlet. A loose or partly seated cord can drop voltage on one leg while still appearing connected.
-
Check the relay connections on the CCU
Unplug the dryer or disconnect power first, then inspect the relay connections on the central control unit. This is the last documented step for the low-voltage condition — beyond it, board-level diagnosis is a technician's job.
-
If power interruptions keep happening, check your home's electrical supply
Repeated PF codes point to an unstable power source rather than a fault inside the dryer itself.
Which Models This Applies To
Documented for the Whirlpool HybridCare Duet heat-pump dryer (2015, L-88 platform). PF is a customer-facing informational code, not one of the platform's F#/E# technical fault codes.

Frequently Asked Questions
What does PF mean on a Whirlpool dryer?
Power Failure — the dryer detected that power was lost while it was running a cycle.
Do I need to restart the whole cycle after PF?
No — press START to continue from where the cycle left off, or POWER to clear the display if you'd rather start over.
Is PF a sign something is broken in my dryer?
Not by itself — it just reports that power was interrupted. If it keeps happening without an obvious cause (like a storm), check your home's electrical supply.
What's the difference between PF and L2?
PF just means power was lost and restored. L2 specifically means low line voltage (under 50V) was detected at the control board — a related but more specific electrical issue, addressed by the F4E4 procedure.
