Professional Repair Time: 45-60 minutes
DIY Repair Time: 60-90 minutes
Difficulty Rating: Moderate (3/5) — Requires hose disconnection and reconnection, spray arm removal, and careful component handling; some mechanical skill recommended

  1. Close the water supply valves at the wall to prevent water discharge during disassembly.
  2. Unplug the dishwasher from the electrical outlet or turn off the circuit breaker to ensure complete power disconnection.
  3. Remove the lower dishrack by pulling it straight out of the dishwasher.
  4. Remove the spray arm by unscrewing the center hub or releasing the retaining clip, depending on your model.
  5. Remove the spray arm support or filter assembly to access the pump housing beneath.
  6. Take multiple photos of the base pump assembly, its mounting location, and all wire and hose connections before disconnecting anything. This is critical for proper reassembly.
  7. Locate the base pump at the bottom of the dishwasher tub in the sump area. It's typically mounted beneath the wash pump or next to it.
  8. Disconnect the wire harness connector from the base pump motor by carefully pulling the connector straight off. Some models may have a locking tab that must be released first.
  9. Label the wire connector with masking tape to identify its position for reassembly.
  10. Locate and disconnect the drain hose that carries water from the pump to the sink drain or garbage disposal. Place a towel beneath the connection to catch residual water.
  11. Locate and disconnect the inlet hose (if applicable) that supplies water from the wash pump to the base pump. Place a towel beneath to catch water.
  12. Support the base pump from beneath to prevent it from falling into the sump when the mounting hardware is removed.
  13. Remove the mounting bolts or screws that secure the base pump to the dishwasher tub or support bracket (typically 2-4 fasteners).
  14. Carefully lift the old base pump out of the dishwasher, tilting it as needed to clear the tub opening and hose connections.
  15. Inspect the old pump for visible damage such as cracked housing, damaged impeller blades, worn seals, or debris lodged in the pump chamber.
  16. Clean the sump area thoroughly, removing any debris, food particles, broken glass, mineral deposits, or standing water that could damage the new pump.
  17. Inspect the drain hose for cracks, kinks, or damage. Replace the hose if it shows signs of wear or blockage.
  18. Inspect the inlet hose (if applicable) for cracks, kinks, or damage. Replace if necessary.
  19. Unpack the new W11414076 base pump from its packaging. Handle carefully to avoid damaging the impeller or seals.
  20. Compare the new pump to the old one to verify all connections, mounting points, hose ports, and wire connector positions match. Ensure you have the correct replacement part.
  21. Position the new base pump in the same location and orientation as the old pump, aligning it with the sump opening.
  22. Align the mounting holes with the dishwasher tub or support bracket.
  23. Secure the base pump with the mounting bolts or screws, tightening firmly but not over-tightening (which can crack the pump housing).
  24. Verify the pump is properly seated and does not wobble or shift.
  25. Reconnect the inlet hose (if applicable) to the pump inlet port, ensuring the connection is tight and secure.
  26. Reconnect the drain hose to the pump outlet port, ensuring it is tight and secure with no kinks.
  27. Verify the drain hose is routed properly and does not have sharp bends or compression points.
  28. Reconnect the wire harness connector to the base pump motor, ensuring it is fully seated and clicks into place. Match the connector to your label or photo.
  29. Verify the connector is secure by gently tugging on it. It should not pull loose.
  30. Reinstall the spray arm support or filter assembly, ensuring it is properly seated and locked into place.
  31. Reinstall the spray arm by aligning it with the support and securing the center hub or retaining clip.
  32. Reinstall the lower dishrack by sliding it back into the dishwasher.
  33. Restore the water supply by opening the supply valves.
  34. Plug the dishwasher back in or turn the circuit breaker back on to restore power.
  35. Run a test cycle (without dishes) on a short wash cycle to verify proper pump operation.
  36. Listen for the base pump motor to start during the drain phase. The motor should run smoothly without unusual noises.
  37. Verify the dishwasher drains properly at the end of the cycle. Water should drain completely from the tub within a reasonable time (typically 1-2 minutes).
  38. Check for water leaks at all hose connections and around the pump housing during the test cycle. If leaks are present, stop the cycle immediately and tighten the connections.
  39. Verify no water backs up into the dishwasher during the wash cycle. Water should drain away properly.
  40. Listen for any unusual noises such as grinding, squealing, rattling, or cavitation sounds from the pump area.
  41. If all checks pass, load the dishwasher normally with a typical load of dishes and run a full cycle to confirm the repair is complete.
  42. If water is not draining, verify the drain hose is not kinked or clogged. Check the drain hose routing to ensure it's not pinched or blocked. Inspect the sink drain or garbage disposal to ensure it's not clogged.
  43. If water backs up during the wash cycle, verify the drain hose is not kinked or clogged. Check the base pump motor is running during the drain phase. Verify the pump impeller is not damaged or blocked by debris.
  44. If the base pump does not start, verify the wire harness connector is fully seated and the circuit breaker has not tripped. Test the electrical outlet with a multimeter.
  45. If water is leaking, stop the cycle immediately and tighten all hose connections. Replace hoses if they are cracked or damaged. Verify the pump housing is not cracked.
  46. If grinding or squealing noises occur, stop the cycle and inspect the pump impeller for debris or damage. Remove any foreign objects and restart the cycle.
  47. If the dishwasher does not drain after 2-3 minutes, the drain pump may not be functioning properly. Verify the pump motor is running and the drain hose is clear.
  48. If problems persist, the issue may be with another component (wash pump, drain valve, hose blockage) rather than the base pump. Further diagnosis is required.

Safety Notes: Always ensure the dishwasher is unplugged before working on it. Close the water supply valves to prevent accidental water discharge. Be prepared for residual water in the hoses and sump—place towels beneath all connections before disconnecting. Never operate the dishwasher without the base pump installed or with the sump exposed. Avoid touching the impeller blades, as they can be sharp.

Always inspect the drain hose for blockages. Before replacing the base pump, verify the drain hose is not clogged or kinked. A blocked drain hose is a common cause of poor drainage that mimics pump failure. Use a plumbing snake or straightened wire hanger to clear any blockages in the hose. Verify water flows freely through the hose before replacing the pump.

Check the sink drain and garbage disposal. If the dishwasher doesn't drain, the sink drain or garbage disposal may be clogged. Fill the sink with water and verify it drains properly. If the sink is clogged, clear it before testing the dishwasher. A clogged sink drain will prevent the dishwasher from draining even with a new pump.

Verify the drain hose is routed properly. The drain hose must be routed without sharp bends or compression points that restrict water flow. Verify the hose is not pinched behind the dishwasher or under the sink cabinet. Reposition the hose if necessary to ensure proper drainage.

Inspect the sump area for debris. Before installing the new pump, thoroughly clean the sump area and pump chamber. Debris such as food particles, broken glass, or mineral deposits can damage the new pump impeller or block water flow. A clean sump ensures optimal pump performance and extends the life of the new assembly.

Test the wash pump to verify it's functioning. If the dishwasher doesn't drain, the wash pump may be faulty and unable to push water to the drain pump. Run a wash cycle and verify water is circulating and spraying from the spray arms. If water is not spraying, the wash pump may be faulty—test or replace it before replacing the base pump.

Check for power supply issues. Verify the dishwasher is receiving proper voltage (120V AC in North America) at the outlet. Low voltage or power surges can damage the pump motor or cause intermittent operation. Use a multimeter to test the outlet voltage.

Inspect for moisture damage. Base pumps can fail due to moisture intrusion or corrosion. Inspect the pump for corrosion, water stains, or mineral deposits. If moisture damage is present, identify and fix the source before installing the new pump, or it will fail too. Common sources include clogged defrost drain or high ambient humidity.

Document everything before disconnecting. Take extensive photos of all wire harness connections and hose routing from multiple angles. Your photos are your roadmap for reassembly and help ensure proper reconnection of all components.

Handle the pump with care. Base pumps contain moving parts (impeller) that can be damaged by rough handling. Handle the pump carefully during removal and installation. Avoid dropping or striking the pump, which can damage the impeller or seals.

This assembly includes pump motor and impeller. The W11414076 is a complete base pump unit—you cannot replace just the motor or just the impeller. If either component fails, the entire assembly must be replaced.

Verify the correct replacement for your model. The W11414076 replaces the W11122133 and is designed for specific Whirlpool and affiliated brand dishwashers. Always verify your dishwasher model number matches one of the compatible models before ordering. Using an incorrect pump can result in non-fit or improper connections.

Monitor the first few cycles before declaring the repair complete. After installing the new base pump, run at least 2-3 full wash cycles and monitor for leaks, unusual noises, or inadequate drainage. Address any issues immediately before they cause further damage or mold growth.

Whirlpool WG04L00566 Dishwasher Upper Spray Arm

The W11414076 is a genuine OEM base pump (also called a drain pump or sump pump) for Whirlpool and affiliated brand dishwashers. This pump is responsible for draining water from the dishwasher tub at the end of the wash cycle. The pump sits at the bottom of the dishwasher in the sump area and is activated during the drain phase to force water out through the drain hose to the sink drain or garbage disposal. The base pump is distinct from the wash pump—while the wash pump circulates water during the wash cycle, the base pump removes water after washing is complete. The pump motor drives an impeller that creates pressure to push water up and out of the dishwasher. Over time, base pumps can fail due to bearing wear, seal degradation, impeller damage from debris (food particles, broken glass), motor burnout from electrical issues, or normal wear from repeated cycling. When the base pump fails, symptoms include water not draining from the tub at the end of the cycle, water backing up into the dishwasher during the wash cycle, standing water in the bottom of the tub, unusual grinding or squealing noises from the sump area, or the pump motor not running. The W11414076 replaces the older W11122133 pump and is a direct plug-and-play replacement. Replacing a faulty base pump restores proper drainage, prevents water damage, and eliminates noise issues caused by a failing pump.
