Frigidaire PLDB998AC1 dishwasher Parts

On a Frigidaire PLDB998AC1 dishwasher, we force a drain by canceling the active cycle; pressing START/CANCEL starts a timed drain (about 90 seconds) and pumps the water out. After it finishes, you can select a new cycle. See the PLDB998AC1 owner’s manual.

Quick steps to force a drain

• Press START/CANCEL once.
• Close the door fully so the unit can run the drain.
• Wait for the drain period to finish (about 90 seconds).
• If needed, select a new wash cycle and press START/CANCEL to begin.
• If water remains, check the drain path below before running another cycle.

If it still will not drain (most common causes)

A forced drain only works if the drain hose and drain system can flow freely.

• Check for kinks or sharp bends in the drain hose under the sink.
• Confirm the drain hose is secured with a clamp and not crushed behind the dishwasher.
• Make sure the drain hose routing includes a high loop (the installation guide calls for a loop at least 32 inches above the floor).
• If connected to a garbage disposer, confirm the knockout plug in the disposer inlet was removed.
• Clean the filter area if it is packed with debris (food soil can restrict pump-out).

Drain connection requirements (what we look for)

Item to verify	What “correct” looks like	What happens if it’s wrong
Drain hose routing	No kinks; no sharp bends	Slow drain or no drain
High loop	Loop at least 32 inches above floor	Backflow; standing water
Sink connection point	Connect above the sink trap (or use an air gap where required)	Dirty water can return to tub
Disposer hookup	Knockout plug removed	Dishwasher cannot push water out

Why it matters

Cancel-draining protects the pump and motor by clearing standing water before you restart a cycle. It also helps you confirm whether the issue is a control/cycle problem or a drain-path restriction.

For a Frigidaire PLDB998AC1 dishwasher, we hard reset the control by canceling the current cycle and then power-cycling the unit. Press START/CANCEL to stop the cycle (it may drain), then turn the dishwasher’s power off at the breaker for 5 minutes and restore power.

Hard reset steps (PLDB998AC1)

• Press START/CANCEL once to stop the current cycle.
• Wait for the dishwasher to finish any drain portion.
• Turn OFF power at the circuit breaker (or remove the fuse).
• Leave power off for 5 minutes.
• Turn power back ON.
• Close the door to latch, select a cycle, then press START/CANCEL to begin.

For model-specific button names, indicator lights, and cycle behavior, follow the PLDB998AC1 owner’s manual.

If it still will not run after a reset

A “reset” clears many control glitches, but it will not fix a door-latch problem, a fill problem, or a drain restriction. Check these common causes:

• Door not fully latched (controls may show a “close door” condition on some versions).
• Control lock enabled; unlock by holding the POWER DRY OFF/NO HEAT DRY pad for 5 seconds.
• No water entering (house shutoff closed, kinked supply line, inlet valve issue).
• Not draining (clogged drain path, disposer plug not removed, drain hose restriction).
• Float/overfill protection stuck or triggered.

If you suspect a fill or drain hardware issue, these model-matched parts are commonly involved:

Symptom	What to check first	Related part (if needed)
Won’t fill	Water supply, inlet screen, valve	Water valve 154637401
Won’t drain	Drain path, high loop, hose clogs	Hose 807117001
Stops mid-cycle or acts “stuck”	Float movement, float switch	Switch 154773201

Why it matters

Resetting restores normal control operation and clears a stalled cycle, but the dishwasher can still pause or refuse to start if it senses an unsafe condition (door open, control lock on, or water temperature and fill checks delaying the timer).

On the Frigidaire PLDB998AC1 dishwasher, the status window can display codes such as PF (power interruption), HO (water heat delay), LO (rinse aid low), CL (door not closed), plus delay-start hours and minutes remaining. For the full list and what to do next, use the PLDB998AC1 owner's manual.

Common PLDB998AC1 status codes and what they mean

These are the most common codes shown in the display for this model:

• PF: Power was interrupted (often after installation or an outage). Clear by touching START/CANCEL.
• HO: Water heat delay; the dishwasher is waiting for water to reach temperature.
• LO: Rinse aid dispenser needs refilling (often appears at end of cycle until the door is opened).
• CL: Close the dishwasher door (cycle will not run with the door unlatched).
• 1H to 9H: Delay start hours (the last hour counts down in minutes).

Quick reference table

Code	What you’ll see	What we recommend
PF	PF in status window	Touch START/CANCEL to clear; rerun cycle if needed
HO	HO flashing	Let it continue heating; verify hot water supply to sink
LO	LO at end of cycle	Refill rinse aid; confirm dispenser cap closes
CL	CL in window	Close and latch door firmly

What to check before assuming a failure

If the dishwasher is not running normally, these checks solve many “code” situations:

• Confirm the door is fully closed and latched (CL can appear if it is not).
• Check the house breaker or fuse if the unit is dead or PF appears repeatedly.
• Make sure the water supply valve is turned on.
• If the cycle seems long, HO can indicate a heating delay.
• If you recently installed the dishwasher, verify grounding and wiring practices in the PLDB998AC1 installation guide.

Why it matters

Reading the display correctly prevents unnecessary part replacement. For example, PF and CL are usually user-action items, while HO often points to incoming water temperature or a heating delay rather than a control problem.
