Whirlpool Washer Drain Pump: Four Names, One Part

A drain pump problem on a Whirlpool washer is a well-worn path, but it is also one where a little diagnosis saves a lot of money. This guide walks the function, the failure signs, the confirmation test, and the replacement itself.

Confirm it, then order it under the right name#

Two mistakes cost money on this repair, and the table covers both: buying a pump that was never faulty, and buying the faulty one's replacement under the most expensive of its four names. Work down until a row matches what you actually have in front of you.

One thing the table cannot decide for you: whether to fit it yourself. The pump is a moderate job — bail the standing water first, photograph the hose and wiring layout, and have fresh clamps ready — but it is a wet one under a machine, and the cost of a professional visit is a diagnostic-and-labor charge on top of the same part. Where this page is worth the most is the row above it: paying the right price for the right part, whoever ends up fitting it.

Denominator: the parts platform above is the one this guide documents — Whirlpool shared with Maytag, KitchenAid and Kenmore-110 machines, four house numbers for one component. Four badges on one platform, not a claim about every Whirlpool part or every model in the range: commonality is decided part by part, so the cross-reference has to be confirmed against the number on your own pump rather than assumed from the badge on the door.

What Your Drain Pump Is Doing#

The drain pump empties the washer at the end of a cycle, spinning an impeller to push water out through the drain hose. When the impeller jams on debris, the motor bearing seizes, or the winding opens, the water has nowhere to go and sits in the bottom of the machine.

Symptoms of a Failing Drain Pump#

• Water stands in the bottom of the washer at the end of a cycle
• A drain fault code appears on models that time the drain
• The pump hums or buzzes but no water moves, a sign of a jammed impeller
• Draining is slow or incomplete rather than fully stopped
• A grinding or rattling noise from the pump as a bearing fails or debris circulates
• A meter shows an open winding across the pump motor terminals
• Debris, a coin, or a shard is visible in the pump housing when opened

Note any code the washer shows before you clear it — it narrows the fault fast.

How to Be Sure Before You Buy#

Rule out the clog first, because it is the free fix. Access the pump, clear the impeller and housing of debris, and turn the impeller by hand feeling for a seized bearing. Then read the motor winding — an open coil confirms a dead pump, while a jam cleared by hand means the pump was never the fault.

Ordering the Right Drain Pump#

Getting the exact part is half the battle. Whirlpool shares a common parts platform across its Maytag, KitchenAid, and Kenmore-110 siblings, so the same component often carries several house numbers. Search both the Whirlpool number and its cross-referenced siblings when you order — identical parts from the same factory frequently price very differently. Whirlpool-platform machines expose a service-diagnostic mode via a button sequence on the tech sheet tucked inside the console or lower panel.

Getting Set Up#

Bail the standing water out of your Whirlpool washer before you start — this is a wet job and getting ahead of the water keeps it off the floor. Confirm the pump against your model, but open the housing first, because a coin or a shard jamming the impeller is the free fix that saves the part. Have towels, a pan, and fresh hose clamps ready for the washer.

The Replacement, Step by Step#

1. Unplug the washer and close both hot and cold supply valves before opening any panel.
2. Bail out standing water, then reach the pump behind the lower front panel or under the washer after removing the access panel.
3. Photograph the wiring, unplug the pump connector, and clamp or catch the hoses before releasing them.
4. Release the hose clamps and the pump mounting screws or twist-lock, and lift the old pump out.
5. Fit the new pump, reseat the hoses with fresh clamps, reconnect the harness, and run a drain to confirm it clears fully with no leaks.
6. Turn everything back on and run a rinse-and-spin to confirm the machine cycles and stays dry underneath.

Tools to Have on Hand#

• A nut driver and pliers for the pump mounts and hose clamps
• A multimeter to read the pump motor winding
• Towels and a shallow pan for the standing water
• A phone camera to record the hose and wiring layout

Verifying the Repair#

A good pump replacement on the Whirlpool washer empties the tub completely, quietly, and without a drip at the fittings. Watch the first drain end to end for leaks. If drainage is still slow, the restriction is likely upstream — a partial clog in the drain line or filter of the washer — so trace the whole path before assuming the new pump is at fault.

Fix It or Replace the Washer?#

A drain pump is a moderate-cost part, so on a washer under about a decade it is a clear replace — especially since a machine that cannot drain is unusable. Only weigh a new unit if the pump is one of several failures on an aging machine.

A Word on Cost#

There is no single honest price to quote, because the drain pump itself and the local labor both vary by model and region. The straight way to think about it: price the specific part against your model number, then add a standard diagnostic-and-labor charge for a professional visit. Get a firm quote on your exact washer rather than trusting a generic figure.

Lifespan and How to Protect It#

Expect many years from a drain pump. What shortens it is debris — coins, shards, and fibers that jam or wear the impeller — so keeping the upstream filter clean and emptying pockets before a cycle both extend its life.

Making the Repair Last#

• Use the washer's filter and empty pockets so coins and debris never reach the impeller
• Clear the pump housing at the first sign of slow drainage rather than forcing cycles
• Never keep running the washer against a jam — a humming pump heats up and burns out
• Address a grinding pump noise early, before a bearing failure strands a tub of water
• Keep the drain line clear so the pump is not fighting a downstream restriction

Mistakes That Cost People Twice#

• Replacing the pump when a coin or a debris clog was jamming an otherwise-good impeller
• Forgetting to bail the standing water first and flooding the floor when the hoses come off
• Reusing tired hose clamps so the new pump seeps at the connections
• Skipping the by-hand impeller spin and missing an obvious jam before buying a part

Putting Off the Repair#

A washer that will not drain is simply out of commission, and leaving standing water in it invites odor and mildew fast. Worse, a pump humming against a jam draws current and heats up, so running it repeatedly against a blockage can burn out a motor that only needed the clog cleared. Address a no-drain promptly.

None of this has to be a solo job. If any step here gives you pause, a technician can confirm the diagnosis and handle the swap so you are not guessing with an expensive part.
