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.

1. Test old pump for continuity (typically 15–40Ω); infinite = open winding.
2. Check for coins, buttons, or debris in inlet/outlet hoses before installing new pump.
3. Inspect pump impeller for cracks or binding—should spin freely by hand.
4. If pump fails repeatedly, check drain hose for kinks, blockages, or excessive runs.
5. Secure all hose clamps tightly to prevent leaks but do not overtighten (may crack plastic).
6. Use only OEM pumps—aftermarket versions may not fit or match flow rate.
7. If pump is noisy but drains, check for foreign objects in housing or impeller.
8. Document installation for warranty and troubleshooting.
9. If washer still won’t drain, check control board, pressure sensor, and door lock.
10. Test with a small load before returning washer to service.
11. Check for leaks during first full cycle after repair.
