Frigidaire Dishwasher PF Error Code: What It Means & What to Check

Q: My Frigidaire dishwasher is showing PF. What does that mean, and what should I do?

A: On many Frigidaire dishwashers, PF usually means power failure or a loss of power was detected during operation. This can happen after a brief outage, breaker trip, loose power connection, or voltage interruption.

Sometimes the fix is simple—restore steady power, reset the dishwasher, and restart the cycle. If the code keeps returning without a clear outage, the issue may involve the outlet, wiring connection, or the dishwasher’s control board. Our friendly technicians in yellow can help diagnose it safely.

What the Frigidaire Dishwasher PF Code Usually Means

The PF code typically indicates the dishwasher detected an interrupted power supply. Common causes include:

• Brief power outage or utility interruption
• Breaker trip or weak breaker connection
• Loose power cord or junction box connection
• Power strip / extension cord use (not recommended)
• Control board issue falsely detecting power loss

Common Symptoms You May Notice

• Dishwasher display shows PF
• Cycle stops unexpectedly
• Unit powers back on but won’t resume normally
• Clock/settings reset after the code appears
• PF code returns repeatedly even without an obvious outage

Safety First (Before You Start)

Power-related issues require extra caution around electricity:

• Do not inspect internal wiring with power on
• Turn off power at the breaker before checking any accessible connections
• Do not use extension cords or adapters with a dishwasher
• If you notice a burning smell, melted insulation, or scorched wiring, stop and call for service

Quick Checks You Can Try at Home

These homeowner-safe checks often help after a Frigidaire dishwasher PF code.

1) Confirm the Home Power Is Stable

Start by checking whether there was a recent outage or brief flicker in your home.

• Check nearby lights/outlets for normal operation
• Ask if anyone noticed a power blink
• If other appliances reset, PF may simply be reporting the interruption

2) Check the Breaker

A partially tripped breaker can cause intermittent power issues.

• Find the dishwasher breaker in your electrical panel
• If tripped, reset it fully (off, then on)
• If it trips again, stop and schedule service/electrical inspection

3) Reset the Dishwasher

After confirming power is restored, perform a reset:

1. Turn off power at the breaker for about 5 minutes
2. Restore power
3. Clear the code (if needed) and start a short cycle

This can help the control recover after a voltage interruption.

4) Check the Plug/Outlet (If Your Model Is Plug-In)

Some dishwashers are hardwired, while others plug into an outlet (often under the sink).

• Make sure the plug is fully seated (with power off first if you plan to handle it)
• Look for signs of moisture near the outlet
• Do not use a loose outlet, extension cord, or power strip

5) Watch for Repeat PF Events

If the code clears but keeps returning, note when it happens.

• Only during heavy appliance use?
• Only mid-cycle?
• During storms or utility fluctuations?

This pattern can help identify whether the issue is house power, wiring, or the dishwasher control.

Common Causes / Likely Parts (If PF Keeps Returning)

If the code comes back and there was no clear outage, these are common items a technician may inspect:

• Power supply connection at plug/outlet or junction box
• Wiring harness / terminal connections
• Door switch / latch circuit (on some models, intermittent power-to-run symptoms can overlap)
• Main control board (power sensing or control fault)
• House electrical issue (breaker, outlet, voltage drop—may require an electrician)

When to Call Beacon

It’s time to schedule service if:

• You get PF repeatedly without any known power outage
• The dishwasher shuts off mid-cycle often
• The breaker trips repeatedly
• You notice burning smell, heat, or discoloration near the connection area
• You want the control and power connections tested safely

Our friendly technicians in yellow can inspect the dishwasher’s power connections and controls, and help determine whether the issue is appliance-related or something your electrician should check.
