What does PF stand for on a dishwasher?
PF on a dishwasher stands for power failure. On a Frigidaire dishwasher like model PLD4375RFC3, it typically means the unit detected an interruption or low/unstable supply voltage; the cycle may pause and then resume once power returns to a normal range (or after you restart the cycle). See the PLD4375RFC3 owner’s manual for the indicator light meanings and operating guidance.
- Press Cancel/Drain (or cancel the cycle) and restart a normal wash cycle.
- Check your home’s breaker/fuse for a trip and reset if needed.
- Make sure the dishwasher is on a properly grounded circuit.
- Avoid running multiple high-draw appliances on the same circuit at the same time.
- If PF returns repeatedly, have the outlet, junction box wiring, and circuit checked by a qualified electrician.
Before you assume a control problem, we recommend these basics:
- Confirm the dishwasher has steady power at the junction box connection.
- Look for signs of a loose connection (intermittent power, flickering lights).
- If the dishwasher stopped mid-cycle, restart and listen for normal fill and wash sounds.
| Display/code | What it usually indicates | What to try first |
|---|---|---|
| PF | Power interruption or low/unstable voltage | Reset breaker, restart cycle |
| No lights | No power to dishwasher | Check breaker, wiring, door latch |
| Other codes (varies) | A detected fault condition | Follow manual troubleshooting |
A power interruption can stop the wash program, leave detergent undissolved, and cause poor cleaning or standing water. Repeated PF events can also point to an electrical supply issue that should be corrected for reliable operation.

What is the most common problem with the Frigidaire dishwasher?
On the Frigidaire PLD4375RFC3 dishwasher, the most common day-to-day complaint we see is poor draining or water left in the tub, usually caused by a blockage in the drain path or a stuck overfill protector (float). These issues often clear with cleaning and a quick inspection.
- Cancel the cycle and let the unit drain; then look for standing water in the bottom.
- Remove and empty the glass trap in the center of the filter area (it catches debris like glass and bones).
- Make sure the overfill protector (float) in the left front corner moves up and down freely about 1 inch; lift it and clean underneath.
- If you have a drain air gap on the countertop, remove the cap and clean it so the dishwasher can drain properly.
- Check the sink/disposer drain connection for a clog (a common choke point).
If cleaning does not fix it, a worn drain component or a leak at a seal can keep the dishwasher from draining correctly or can leave water where it should not be.
Common parts to consider for PLD4375RFC3:
- Hose 807117001 if the drain hose is kinked, split, or internally clogged
- Dishwasher drain pump 154580301 if you hear humming but get little or no drain flow
- Dishwasher door seal 809006501 if you see water leaking at the bottom of the door (leaks can mimic “drain” complaints)
| Symptom | Most common cause | What we recommend |
|---|---|---|
| Water left in tub | Clog in drain path or air gap | Clean glass trap, air gap, and drain connection |
| Overfilling or odd fill behavior | Stuck float/overfill protector | Clean under float; confirm free movement |
| Won’t fill or fills slowly | Inlet valve screen clogged | Clean inlet valve screen per install instructions |
| Leaks at door bottom | Door seal worn or mis-seated | Inspect/replace lower door seal |
Drain and float issues can lead to odors, poor cleaning, and repeated cycle interruptions. Keeping the filter area, glass trap, and drain path clear helps the wash motor and heater do their jobs efficiently.
For model-specific care and indicator light guidance, follow the PLD4375RFC3 owner's manual.

How can I force my Frigidaire dishwasher to drain?
To force a drain on your Frigidaire dishwasher model PLD4375RFC3, press and hold Start/Cancel for about 3 to 5 seconds, then close the door so the drain pump can run. If the drain hose is loose or disconnected, water can discharge as soon as the door closes.
- Turn off the dishwasher if you see water leaking under the sink.
- Keep a towel and shallow pan ready at the sink cabinet.
- Make sure the drain hose is secured to the sink drain, disposer, or trap with a clamp.
- Confirm the drain hose has no sharp bends or kinks that restrict flow.
- Verify the drain hose loop is routed high under the counter (a high loop helps prevent backflow).
A forced drain command will not fix a physical restriction. These are the most common causes on PLD4375RFC3 installations:
| Symptom | Most likely cause | What to check first |
|---|---|---|
| Hums but little or no water leaves | Kinked or pinched drain hose | Inspect routing under the sink and behind the unit |
| Drains slowly | Partial clog in hose or air gap | Clean the air gap (if installed) and check hose for debris |
| Won’t drain at all | Drain hose not attached or blocked | Confirm hose is attached to the drain pump and sink connection |
| Water backs up into tub | Improper drain connection | Entry to sink drain must be above the trap; disposer plug must be removed if connected |
If the hose is damaged, split, or permanently restricted, replacement is often the fastest fix. Use the correct drain hose for this model: hose 807117001.
Forcing a drain is a quick way to clear standing water before troubleshooting, but proper drain hose routing and a secure connection are what keep the PLD4375RFC3 draining reliably and help prevent leaks and sink backflow.
For diagrams and routing requirements (high loop, air gap options, disposer connection), follow the PLD4375RFC3 installation guide.

How to fix a Frigidaire dishwasher power failure?
A power failure on a Frigidaire PLD4375RFC3 dishwasher is usually cleared by resetting the control and then restarting a cycle. We recommend confirming the door is fully latched, restoring household power at the breaker, and then running a quick test cycle using the steps in the PLD4375RFC3 owner's manual.
- Make sure the door is closed and latched firmly.
- Turn the dishwasher off, then restore power at the circuit breaker (or fuse) if it tripped.
- Wait 10 to 15 seconds after power is restored so the control can reboot.
- Select a normal cycle and press Start.
- If the unit is unresponsive, disconnect electrical power before servicing (per the safety guidance in the manual).
Power interruptions can also cause cycle issues (including sanitize not completing). Check these common causes:
- Loose plug or junction box wiring (if hardwired).
- Weak breaker, shared circuit, or frequent voltage dips.
- Moisture intrusion at the door causing intermittent control behavior.
- A failing electronic control (symptoms can include random lights or no response).
- Control lock enabled (some models lock/unlock by holding a pad for about 3 seconds).
If power is stable and the dishwasher still will not run, these model-specific parts are often involved:
| Symptom | What it points to | Example part for PLD4375RFC3 |
|---|---|---|
| No fill, no wash after Start | Water supply not entering | Dishwasher water inlet valve 154637401 |
| Lights act odd, won’t respond | Control not processing inputs | Dishwasher electronic control board 5304514670 |
| Stops mid-cycle, won’t drain | Drain system issue | Hose 807117001 |
A PF condition can interrupt heating and sanitizing; the manual notes sanitize criteria may not be met after a power failure or cycle interruption. Resetting correctly and confirming stable power helps prevent repeat shutdowns and incomplete cleaning.
