If your Kenmore 11047512602 front-load washing machine finishes a cycle but leaves standing water in the drum, or shows a drain-related error code, the drain pump is one of the most likely causes. Before replacing the pump, check the pump filter and drain hose for clogs, since debris is a common and much easier fix. If the filter is clear and the hose is not blocked, the pump itself may have failed and need replacement.

This guide explains what the drain pump does, what usually causes it to fail, how to diagnose the problem step by step, and how to replace the pump on a Kenmore 11047512602 washer.

What Does the Drain Pump Do?

The drain pump removes water from the tub during the drain and spin portions of each wash cycle. It sits near the bottom front of the washing machine and works together with the pump filter, which catches lint, coins, and small debris before they reach the pump itself.

When the pump runs correctly, water is pushed out through the drain hose between cycle stages. When it fails, either from a clog or a burned-out motor, water is left sitting in the drum and the washer may stop mid-cycle or display a drain-related error code.

Common Causes of Drain Pump Failure

• Clogged pump filter: Lint, coins, buttons, and small clothing items can collect in the filter over time and restrict water flow before it even reaches the pump.

• Foreign objects lodged in the pump itself: Coins or small items that get past the filter can jam the pump impeller directly.

• Burned-out pump motor: Like any motor, the drain pump motor eventually wears out after years of use and stops running.

• Kinked or clogged drain hose: A blocked or bent hose downstream of the pump can prevent water from draining even if the pump is working.

• Failed door lock switch: Some washers will not complete a drain cycle if the door lock switch is not sending the correct signal, which can look like a pump problem.

• Worn drive belt on belt-driven models: On some Kenmore washers, the pump is powered by the same belt system as the drum, so a worn belt can also affect draining.

Signs Your Drain Pump Needs Attention

Common Symptoms

• Washer finishes a cycle with standing water still in the drum

• Washing machine displays a drain-related error code, such as an OE or F02-type code

• A humming noise during the drain cycle with little or no water actually leaving the tub

• Washer starts spinning without draining first, leaving clothes soaked at the end of the cycle

• No sound at all from the pump during what should be the drain portion of the cycle

Quick Diagnostic Checklist

• Open the pump filter access panel at the lower front of the washer and check for visible debris or blockage.

• Listen during the drain cycle. A humming sound with no water movement suggests a clogged or jammed pump, while total silence suggests the pump is not receiving power or the motor has failed.

• Check the drain hose behind the washer for kinks, or disconnect and flush it to rule out a downstream blockage.

• If the filter and hose are both clear and the pump still does not respond, plan to test or replace the pump itself.

Parts and Tools Needed

Safety Precautions Before You Start

• Unplug the washing machine before opening any access panel or touching the pump.

• Have towels and a shallow pan ready since the tub and pump body can hold water even when the drum looks empty.

• Avoid working on wiring with wet hands or while standing in pooled water.

• If you need to move the washer away from the wall, get a second person to help.

Step-by-Step Drain Pump Troubleshooting and Replacement

1. Check and clean the pump filter first. Unplug the washer and open the small access panel at the lower front. Place a shallow pan underneath before opening the filter cap because residual water will drain out. Remove and clean the filter thoroughly, checking for coins, lint, or small clothing items.

2. Inspect the drain hose. Check the drain hose behind the washing machine for kinks or visible blockages. Disconnect it if needed and flush it out to confirm water flows freely.

3. Access the pump body. If the filter and hose are clear but the washer still will not drain, remove the lower front access panel using the nut driver to expose the pump body.

4. Disconnect the pump hoses and wiring. Use pliers to release the spring clamps securing the drain and recirculation hoses to the pump body, and disconnect the wire connectors from the pump motor. Take a photo first so reassembly is accurate.

5. Remove the old pump. Remove the mounting screws or bolts securing the pump to the washer base, then pull the pump body out. If the pump and motor are separate components on your model, remove the motor mounting screws to separate them.

6. Install the new pump. Set the new pump into position and secure it with the original mounting hardware. Reconnect the wire connectors to the pump motor, then reattach the drain and recirculation hoses using the spring clamps.

7. Reassemble the washer. Reinstall the lower front access panel and secure the screws. You can leave the panel off temporarily if you want to perform a leak test first.

8. Test the repair. Plug the washing machine back in and run a short fill and drain cycle. Watch the pump, hose connections, and floor closely for leaks while it runs.

How to Test After Replacement

• Run a fill, drain, and spin cycle and confirm water is fully removed from the tub at each stage.

• Watch the pump housing and hose connections closely during the first cycle for any dripping or leaking.

• Listen for a smooth pump sound. Some initial roughness is normal while trapped air works out of the system, but it should settle within the first cycle.

• Confirm that any previous drain-related error code does not reappear during the next normal cycle.

Common Mistakes to Avoid

• Replacing the pump without first checking the filter and drain hose, which are much simpler and cheaper fixes if debris is the real cause

• Forgetting to place a pan or towels under the pump filter before opening it, which can create a much larger water mess than expected

• Mixing up the drain hose and recirculation hose connections during reassembly on models that have both

• Overtightening spring clamps or mounting screws, which can crack plastic housings

• Skipping the leak test with the access panel left open, which can hide a loose connection until later

Maintenance Tips to Prevent Future Drain Pump Problems

• Clean the pump filter every month or two, especially if you regularly wash items with pockets that may contain coins or small objects.

• Empty pockets before every load as a simple habit that prevents most foreign-object jams.

• Periodically check the drain hose for kinks, especially if the washer has been moved or repositioned recently.

• Avoid letting lint and debris build up in the filter access area, since this is one of the easiest and cheapest ways to prevent pump strain over time.
