What does error code 24 mean on a Whirlpool dishwasher?

Error code 24 on a Whirlpool dishwasher means the unit has detected a drainage failure and cannot pump water out of the tub.

This error specifically points to a problem within the water removal system. When the control board signals that water is remaining after a cycle, it stops operation to prevent flooding.

The control board senses standing water in the bottom of the tub after a cycle.
A blocked drain hose prevents the expelled water from reaching the household plumbing.
A malfunctioning drain pump fails to activate or lacks sufficient rotational power.
A clogged garbage disposal connection restricts outgoing water flow completely.
An obstructed or stuck check valve prevents water from moving in one direction.

Why is my Whirlpool dishwasher showing error code 24?

This code is usually triggered by food debris clogs, a pinched drain hose, or a failing drain pump motor.

Understanding the root cause helps you target the repair efficiently. Most drainage failures stem from everyday kitchen debris or installation quirks that restrict water pathways.

Food particles accumulate in the sump filter and block the pump intake area.
The drain hose becomes kinked behind the dishwasher chassis during routine movement.
The knockout plug inside a new garbage disposal inlet was left in place.
The drain pump mechanical components experience electrical failure or internal jamming.
House plumbing blockages further down the sink line back up into the unit.

What are the quick fixes to try first?

Start by clearing the filter, straightening the drain hose, and checking the garbage disposal connection.

Always unplug the dishwasher or shut off the circuit breaker before accessing internal components to prevent electrical shock. Perform these quick safety checks before calling a repair service.

Unplug the dishwasher or turn off the power at the electrical breaker panel.
Remove the lower dish rack and clean out any trapped food debris from the bottom filter.
Pull the dishwasher forward gently to inspect the drain hose for any visible kinks or sharp bends.
Disconnect the drain hose from the garbage disposal and clear out any hardened buildup inside the nipple.
Run a short rinse cycle after restoring power to verify if error code 24 is cleared.

What should you do if the initial fixes fail?

Inspect the drain pump for blockages, test continuity with a multimeter, or clean the check valve.

If simple cleaning steps do not resolve error code 24, you must inspect deeper mechanical parts. Unplug the appliance before inspecting wiring harnesses or removing the drain pump assembly.

Shut off the household circuit breaker supplying power to the dishwasher unit.
Access the underside or kickplate area to locate the electric drain pump assembly.
Disconnect the wire harness and remove the pump to check the impeller for jammed debris.
Inspect the rubber check valve inside the sump housing for tears, wear, or sticky residue.
Reassemble all components securely and run a test cycle to confirm proper operation.

Which fix matches your specific drainage symptom?

Match your observation to the appropriate troubleshooting action using the quick reference matrix below.

Different symptoms point to distinct underlying causes within the drainage system. Use this reference table to quickly identify the exact remedy for your specific situation.

Symptom	Likely cause / fix
Standing water in tub	Clean filter / clear drain hose
Humming noise, no drain	Jammed pump / remove debris
New installation error	Remove disposal knockout plug
Intermittent error 24	Straighten kinked hose
Pump runs continuously	Replace faulty water sensor

When should you stop troubleshooting and call a professional?

Call a qualified technician if you encounter electrical wiring damage, failed pump motors, or persistent leaks.

Certain repairs require professional expertise and specialized tools to resolve safely. Continuing to service electrical or sealed components without proper training can void your warranty or cause injury.

The drain pump motor shows electrical failure or lacks continuity during multimeter testing.
Internal wiring harnesses appear scorched, frayed, or damaged beyond simple reconnection.
Error code 24 persists immediately after replacing the drain pump and clearing all hoses.
Water leaks originate from hidden internal components beneath the dishwasher basin.
You feel uncomfortable performing basic electrical disconnects or appliance disassembly.

What information should you prepare before calling for service?

Have your exact model number, serial number, warranty status, and a list of attempted fixes ready.

Providing precise details to customer support or a repair technician speeds up diagnosis. Locate the identification sticker on the inner edge of the dishwasher door frame before placing your call.

Locate the exact appliance model and serial number on the interior door frame label.
Check your original purchase receipt or appliance warranty documentation details.
Write down every troubleshooting step you already attempted to clear error code 24.
Note any unusual noises or specific cycle phases when the error code appears.
Confirm your contact information and physical address for the service dispatch.

How can you keep error code 24 from coming back?

Prevent recurring drainage issues by scraping plates, cleaning filters monthly, and running hot water.

Routine preventive maintenance extends the lifespan of your appliance and prevents unexpected breakdowns. Simple daily habits keep food waste out of your dishwasher’s critical drainage components.

Scrape large food chunks off dinnerware before loading them into dishwasher racks.
Remove and wash the bottom sump filter with warm soapy water on a monthly basis.
Run the kitchen sink garbage disposal before starting a dishwasher cycle to clear the line.
Run a monthly cleaning cycle using specialized dishwasher cleaner or white vinegar.
Inspect the under-sink drain hose periodically to ensure it remains free of kinks.

Frequently Asked Questions

Can I run my Whirlpool dishwasher safely while error code 24 is displayed?

You should not run the dishwasher while error code 24 is active because standing water can cause overflow or motor damage. Clear the drainage blockage and reset the machine before starting a new wash cycle.

Where is the drain filter located on a modern Whirlpool dishwasher model?

The drain filter is located at the bottom center of the dishwasher tub underneath the lower dish rack. Twist the cylindrical plastic filter counterclockwise to lift it out for cleaning.

What tools do I need to fix Whirlpool dishwasher error code 24?

You typically need a pair of pliers, a screwdriver, a bucket, towels, and a flashlight. A digital multimeter may be required if you need to test electrical continuity on the drain pump motor.

Does a new garbage disposal installation cause error code 24?

Yes, a new garbage disposal often features a plastic knockout plug inside the dishwasher inlet port. If this plug is not removed during installation, water cannot drain and triggers error code 24.

How do I reset my Whirlpool dishwasher after fixing the drain issue?

You can reset the appliance by pressing the Cancel or Power button for several seconds. Alternatively, unplug the dishwasher or turn off the circuit breaker for one minute to clear the error code memory.

Bottom Line

Unplug your dishwasher and check the filter and drain hose for clogs immediately to resolve error code 24.
