Frigidaire FDB710LCQ0 dishwasher Parts

For Frigidaire dishwasher model FDB710LCQ0, the most common issue we see is poor cleaning (food soils left on dishes). It’s usually caused by blocked spray-arm rotation, low incoming water temperature, low water pressure, or loading that prevents water from reaching surfaces; the fix is often cleaning and setup, not a major repair (see the owner's manual).

Most common symptoms and what they usually mean

• Food soils left on dishes: spray arms blocked, detergent issues, or cycle selection
• Water left in the bottom of the tub: draining problem (kinked drain hose, disposer knockout plug)
• Won’t run: door not fully latched, breaker/fuse issue, cycle not set correctly
• Won’t fill: water supply off, inlet hose kink, overfill protector stuck
• Long cycle times: water-heating delay or options that extend the cycle

Quick checks we recommend first (FDB710LCQ0)

Use these checks because they directly match the troubleshooting guidance for this model:

• Confirm incoming water temperature is at least 120°F (49°C)
• Confirm home water pressure is 20 to 120 psi
• Reload to avoid nesting; make sure nothing blocks spray-arm rotation
• Choose a longer cycle or use a high-temperature wash option when needed
• If it won’t drain: check for a kinked drain hose and verify the disposer inlet knockout plug is removed (if connected)

Parts that commonly solve cleaning and leak complaints

If cleaning is poor even after correcting loading and water conditions, these model-matched parts are common fixes:

Problem you notice	Common cause	Model-matched part to check
Dishes still dirty	Spray arm not rotating or clogged	Dishwasher spray arm 5304517203
Dishwasher not filling well	Inlet valve not opening fully	Valve 154637401
Leaks at the door	Worn lower door seal	Gasket 809006501

Why it matters

Poor cleaning is often a setup issue (water temperature, pressure, loading) that also affects drying and cycle time. Fixing the basics first prevents unnecessary part replacement and helps the wash system (spray arms, sump, and heater) perform the way it was designed.

On a Frigidaire FDB710LCQ0 dishwasher, most error conditions clear by canceling the cycle and restoring power; if the code returns, fix the underlying issue (drain restriction, overfill, or a door-latch problem) because the control will re-detect the fault. Use the steps in the owner's manual for your exact control behavior.

Quick reset steps (safe order)

• Press and hold Start/Cancel (or Cancel) for about 3 seconds to stop the cycle and drain.
• Wait 1 minute, then select a new cycle and press Start.
• If the code stays on: turn OFF power at the breaker for 5 to 10 minutes, then turn it back ON.
• Confirm the water supply is turned on and the door is closed and latched (both are common “won’t run” causes).
• Run a short cycle and watch for the code to return.

If the code comes back: what to check first

Many “reset” failures happen because the dishwasher is correctly sensing a real problem.

• Not draining or water left in tub: check for a kinked drain hose, disposer knockout plug still installed, or a pause mid-cycle.
• Not filling: verify the shutoff valve is open; if the dishwasher still will not fill, the valve 154637401 is a common fix when the inlet valve fails.
• Overfill symptoms: check the float area for debris; a stuck float circuit can involve the switch 154773201.
• Door won’t latch: inspect the strike and latch alignment; the strike 154662601 is the wear item that often causes intermittent latching.

What you should see after a successful reset

What happens	What it usually means
Code clears and cycle runs normally	Temporary glitch or a one-time interruption
Code clears but returns during fill/drain	A real water, drain, or float-related issue
Dishwasher will not start at all	Door not latched, power issue, or cycle not set correctly

Why it matters

Resetting clears the control’s active alarm, but it does not remove the condition that triggered it. Fixing drain, fill, or latch problems prevents repeat errors and helps protect the pump, heater, and wiring.

PF means power failure. On a Frigidaire dishwasher like model FDB710LCQ0, it indicates the dishwasher detected a loss or drop in electrical power during operation; once power is stable again, you can restart the cycle normally (check the reset steps in the FDB710LCQ0 owner's manual).

What to do when you see PF

• Press Cancel/Drain (or turn the cycle selector to cancel) and let the dishwasher drain if it was mid-cycle.
• Verify the dishwasher is plugged into a properly grounded outlet (3-prong).
• Check your home breaker or fuse for a trip.
• Start a short cycle and listen for normal fill and wash sounds.
• If PF returns repeatedly, avoid running the dishwasher on the same circuit as high-draw appliances.

Quick checks that solve most PF situations

The FDB710LCQ0 needs a stable 120V, 60 Hz, 15-amp grounded supply. Power interruptions, loose plugs, or a tripped breaker can trigger PF.

Check	What you’re looking for	Result
Breaker/fuse	Tripped breaker or blown fuse	Restore power and retry cycle
Outlet/plug	Loose connection, damaged cord, missing ground	Correct connection before running
Cycle restart	Unit fills, spray arms run, then drains	Confirms normal operation

Why it matters

A PF alert is mainly a safety and reliability indicator. Dishwashers use timed fills, heating, and draining; a power drop can interrupt those steps and leave water in the tub or stop heating mid-cycle.

When PF points to a dishwasher issue

If power in the home is stable but PF keeps appearing, focus on basic operation items first (fill, drain, and wash action). For example, if the dishwasher is not filling consistently, the water inlet valve can be a suspect; for this model, see the valve 154637401.

To force a drain on your Frigidaire FDB710LCQ0 dishwasher, cancel the cycle (press and hold the Start/Cancel control for about 3 to 5 seconds), then close and latch the door so the drain pump can run. If it still will not drain, focus on the drain hose and disposer connection.

Steps to trigger a drain

• Press and hold Start/Cancel for 3 to 5 seconds.
• Close the door fully and make sure it latches.
• Wait several minutes for the drain pump to finish.
• If the dishwasher is paused, cancel the cycle so it can move to drain.
• Confirm the exact button sequence for your control panel in the owner's manual.

If it still will not drain

The FDB710LCQ0 manual and installation guidance point to these common causes:

• Drain hose kinked or pinched: Route the hose so there are no sharp bends restricting flow.
• Drain hose not attached correctly: Verify the hose is properly connected to the drain pump and secured at the sink drain or disposer.
• Improper drain hose routing: Use the recommended high loop routing described in the installation guide to prevent poor draining and backflow.
• Food waste disposer issue (if connected): Make sure the disposer is empty and the inlet knockout plug has been removed.
• Drain air gap clogged (if installed): Clean the air gap so the dishwasher can drain properly.

Fast checklist

Check	What “good” looks like	What it prevents
Door latch	Door closes and latches fully	Drain pump not running
Drain hose	No kinks, not crushed under unit	Slow or no drain
Hose routing	High loop per install instructions	Backflow, poor draining
Disposer inlet	Knockout plug removed	Total drain blockage

Why it matters

When a dishwasher cannot drain, dirty water stays in the sump; that reduces cleaning performance and can cause odors. Correct drain hose routing and a clear disposer connection are the most important basics for reliable draining.
