Imagine this scenario: The washing machine’s cycle has finished, you open the lid, only to find your clothes still soaking in murky water instead of being dry. This usually means there’s a problem with the drainage process. For many users of top-loading washing machines from well-known brands such as Amana, Kenmore, Maytag, and Whirlpool, the part number WPW10730972 may be the key replacement part you need—the washing machine drain pump assembly.
This article will focus on the WPW10730972 (W10130913) model, providing an in-depth analysis of its functions and common causes of failure, along with practical replacement and maintenance guidelines to help you quickly restore your washing machine’s normal drainage function.
Why the Drain Pump Is the Washing Machine’s “Unsung Hero”
For top-drain front-loading washing machines (which are very common in American households, as most homes have laundry rooms on the second floor or in the basement, and top drainage allows wastewater to be pumped upward into the drainpipe), the drain pump is the core power component. Driven by a motor, it causes the impeller to rotate at high speed, creating negative pressure inside the pump chamber. This forces the dirty water from the inner drum out and pushes it into the drainpipe, which is located above the top of the machine.
A properly functioning drain pump ensures:
Efficient drainage: Quickly empties wastewater from the drum, shortening the wash cycle.
Prevents odors: Timely drainage prevents wastewater from stagnating, which can lead to mold and unpleasant odors.
Protection of clothing: Thorough spin-drying is a crucial preliminary step for drying clothes.
How can you tell if the drain pump assembly is damaged?
When a washing machine exhibits the following signs, it likely means that the WPW10730972 (W10130913) drain pump assembly needs to be inspected or even replaced:
1. Specific error codes appear
The machine’s display is the first place to look for problems. Many modern washing machines display error codes when they cannot drain properly. For example, brands like Whirlpool often display error codes such as F9, E1, or F02; LG models may display OE, E03, or E21. These codes typically indicate a drainage timeout or a drain pump failure.
2. Abnormal drainage or unusual noises from the machine
The pump is running but not draining water: You may hear a “humming” sound from the drain pump, but the water level does not decrease. This usually means the impeller is jammed by foreign objects (such as coins, buttons, or lint), or the drain hose is kinked.
The pump is not working at all: If the washing machine shows absolutely no signs of draining and you cannot hear any motor running, the motor windings may be burned out, the leads may have come loose, or the start capacitor may have failed.
Unusual noises: During normal operation, the drain pump produces a steady sound. If you hear a high-pitched grinding or clicking noise, it is usually caused by a deformed impeller, worn bearings, or a foreign object stuck inside.
3. Water Leak from the Pump Housing
If you notice water pooling at the bottom of the washing machine, it may be due to aging seals on the drain pump or an uneven installation causing a leak at the joint.

Replacement and Maintenance Guide: DIY or Call a Professional?
For users who are handy, replacing the drain pump is not an insurmountable task. Here is a basic overview of the process (be sure to refer to your washing machine’s repair manual for specific steps):
Safety First: Unplug the power cord and turn off the water supply valve.
Prepare for Drainage: Since there will be residual water in the pump housing and connected hoses, be sure to place a large drip tray under the machine. Remove the Old Pump: You’ll typically need to remove the front or rear cover to locate the drain pump at the bottom of the machine. Loosen the metal clips securing the pipes, then carefully disconnect the two hoses and the electrical plug connected to the pump housing.
Cleaning and Inspection: After removing the old pump, take a moment to clear any blockages from the inside of the connecting hoses. Many small items of clothing or debris get trapped here, causing drainage problems.
Installing the New Pump: Install the new WPW10730972 drain pump assembly, ensuring the rubber seals are properly seated to prevent leaks, then reconnect all hoses and wiring harnesses.
Maintenance Tips:
Clean the Filter Regularly: Most front-loading washing machines have a drain pump filter located in the lower right corner of the machine. Cleaning it once a month can significantly reduce the risk of the drain pump becoming clogged or burning out.
Be Mindful of Laundry Items: Small items with elastic cords, plush toys, or rugs with rubber backing can shed fibers or small parts during the wash cycle, which may clog the drainage system. It is recommended to use a laundry bag.
