Professional: 30-45 minutes | DIY: 60-90 minutes | Classification: Medium repair

Tools Required: Phillips head screwdriver, flathead screwdriver, pliers, towels or shallow pan (for water), work gloves, flashlight

1. Disconnect Power and Water: Unplug the washer from the electrical outlet. Turn off both hot and cold water supply valves at the wall.
2. Access the Pump (Front-Load Models): Tilt the washer back against a wall or have a helper support it. Remove the lower front access panel by releasing clips or removing screws. The drain pump is typically located at the front bottom of the machine.
3. Access the Pump (Top-Load Models): Unplug the washer and pull it away from the wall. Remove the rear access panel or cabinet screws to access the pump assembly from the back or bottom.
4. Prepare for Water Drainage: Place towels and a shallow pan beneath the pump area. There will be residual water in the pump and hoses.
5. Disconnect Drain Hose: Loosen the hose clamp securing the drain hose to the pump outlet using pliers or a screwdriver. Pull the hose off the pump and allow water to drain into your pan.
6. Disconnect Inlet Hoses: Remove hose clamps from the pump inlet connections (typically from the tub). Disconnect both hoses and allow them to drain.
7. Disconnect Electrical Connector: Locate the wire harness connector attached to the pump motor. Press the release tab and carefully pull the connector straight off the pump terminals.
8. Remove Mounting Hardware: Remove the screws or bolts securing the pump assembly to the washer frame or mounting bracket. Note the orientation of the pump for proper reinstallation.
9. Remove Old Pump: Carefully lift the WW01F02056 drain pump assembly out of the washer. Check the pump housing and impeller for debris or damage.
10. Install New Pump: Position the new drain pump assembly in the mounting location, ensuring proper alignment with mounting holes and hose connections.
11. Secure Mounting Hardware: Install and tighten all mounting screws or bolts to secure the pump firmly to the frame.
12. Reconnect Inlet Hoses: Attach the inlet hoses from the tub to the pump inlets. Secure with hose clamps, ensuring tight connections to prevent leaks.
13. Reconnect Drain Hose: Attach the drain hose to the pump outlet and secure with a hose clamp. Ensure the connection is tight and properly seated.
14. Reconnect Electrical Connector: Plug the wire harness connector onto the new pump motor terminals until it clicks securely into place.
15. Reassemble Access Panels: Reinstall the front or rear access panel and secure with all screws or clips.
16. Restore Power and Water: Plug the washer back in and turn on the water supply valves.
17. Test Operation: Run a drain/spin cycle without clothes to verify the new pump operates correctly, drains water properly, and check for any leaks around hose connections.

Debris Inspection Critical: Before installing the new pump, ALWAYS check the drain filter housing and pump inlet for foreign objects (coins, buttons, bobby pins, small socks, etc.). These items are the leading cause of premature pump failure. Remove the drain filter (usually accessed from the front lower panel) and clean it thoroughly. Also inspect the drain hose for kinks, clogs, or restrictions that could cause back-pressure on the new pump. Hose Clamp Upgrade Recommended: If the original hose clamps are worn, corroded, or spring-type clamps, replace them with new worm-drive screw clamps for more reliable, leak-proof connections. This prevents future leaks and ensures proper water evacuation. Pump Orientation Matters: The drain pump must be installed in the correct orientation with the outlet pointing toward the drain hose connection. Installing it backwards or at the wrong angle can cause drainage issues, noise, and premature failure. Take photos before removal to ensure correct reinstallation. Electrical Connection Verification: After connecting the wire harness, gently tug on the connector to ensure it's fully seated and locked. A loose connection can cause intermittent operation, error codes, or complete pump failure. Test the pump by running a drain cycle before reassembling the entire washer. Common Failure Pattern: If your pump failed due to a clogged drain filter or kinked drain hose, address these issues before installing the new pump. Failure to do so will cause the new pump to fail prematurely under the same conditions. Always run a test cycle and check for leaks before pushing the washer back into place.
