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. Locate the pump and motor assembly at the bottom of the dishwasher tub, typically beneath the spray arm support or in the sump area.
5. Take multiple photos of the pump assembly, its mounting location, and all wire and hose connections before disconnecting anything.
6. Disconnect the wire harness connector from the pump motor by carefully pulling the connector straight off. Some models may have a locking tab that must be released first.
7. Locate and disconnect the inlet hose that supplies water to the pump. Place a towel beneath the connection to catch residual water.
8. Locate and disconnect the outlet hose(s) that carry water from the pump to the spray arms. Place towels beneath to catch water.
9. Locate and disconnect the drain hose (if the pump is also responsible for draining). Place a towel beneath to catch water.
10. Support the pump assembly to prevent it from falling into the sump.
11. Remove the mounting bolts or screws that secure the pump assembly to the dishwasher tub or support bracket (typically 2-4 fasteners).
12. Carefully lift the old pump and motor assembly out of the dishwasher, tilting it as needed to clear the tub opening.
13. Inspect the old pump assembly for damage, debris, or wear. Check the impeller for cracks or damage.
14. Clean the sump area thoroughly, removing any debris, food particles, or mineral deposits that could damage the new pump.
15. Inspect the inlet, outlet, and drain hose connections for cracks, kinks, or damage. Replace hoses if necessary.
16. Unpack the new W11612326 pump and motor assembly from its packaging.
17. Compare the new assembly to the old one to verify all connections, mounting points, and hose ports match. Ensure you have the correct replacement part.
18. Position the new pump and motor assembly in the same location and orientation as the old assembly.
19. Align the mounting holes with the dishwasher tub or support bracket.
20. Secure the pump assembly with the mounting bolts or screws, tightening firmly but not over-tightening (which can crack the pump housing).
21. Verify the pump is properly seated and does not wobble or shift.
22. Reconnect the inlet hose to the pump inlet port, ensuring the connection is tight and secure. Use a hose clamp if necessary.
23. Reconnect the outlet hose(s) to the pump outlet port(s), ensuring all connections are tight and secure.
24. Reconnect the drain hose (if applicable), ensuring it is tight and secure.
25. Verify all hose connections are properly oriented and not kinked or twisted.
26. Reconnect the wire harness connector to the pump motor, ensuring it is fully seated and clicks into place.
27. Verify the connector is secure by gently tugging on it.
28. Reinstall the lower dishrack by sliding it back into the dishwasher.
29. Restore the water supply by opening the supply valves.
30. Plug the dishwasher back in or turn the circuit breaker back on to restore power.
31. Run a test cycle (without dishes) on a short wash cycle to verify proper pump operation.
32. Listen for the pump motor to start within a few seconds of the cycle beginning. The motor should run smoothly without unusual noises.
33. Verify water is spraying from the spray arms during the wash cycle. Water should spray forcefully and cover all areas of the tub.
34. Check for water leaks at all hose connections during the test cycle. If leaks are present, stop the cycle and tighten the connections.
35. Verify the dishwasher drains properly at the end of the cycle. Water should drain completely from the tub.
36. Listen for any unusual noises such as grinding, squealing, or rattling from the pump area.
37. If all checks pass, load the dishwasher normally and run a full cycle to confirm the repair is complete.
38. If water is not spraying, verify the outlet hose is connected and not kinked. Check the spray arm support for blockages.
39. If the pump does not start, verify the wire harness connector is fully seated and the circuit breaker has not tripped.
40. If water is leaking, stop the cycle and tighten all hose connections. Replace hoses if they are cracked or damaged.

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 pump assembly installed.

Always inspect the spray arm support and sump for debris. Before installing the new pump, thoroughly clean the sump area and spray arm support. 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.

Check the inlet screen filter. Many dishwashers have a screen filter at the pump inlet that catches debris. If this filter is clogged, the pump will not receive adequate water flow and will work harder, shortening its life. Clean or replace the inlet filter as part of the pump replacement.

Verify all hose connections are tight. Loose hose connections are a common cause of water leaks and reduced water pressure. Use hose clamps on all inlet, outlet, and drain hose connections to ensure they are secure. Tighten clamps firmly but do not over-tighten, which can crack the hoses.Inspect the spray arm nozzles for blockages. If water is not spraying forcefully after pump replacement, the spray arm nozzles may be clogged with mineral deposits or debris. Remove the spray arms and soak them in white vinegar to dissolve mineral buildup. Use a small wire or toothpick to clear individual nozzles.

Test the inlet water valve. If the dishwasher does not fill with water after pump replacement, the inlet water valve may be faulty. The pump requires adequate water supply to operate. Test the inlet valve with a multimeter to verify it's opening during the fill cycle.

Check for kinks or crushing in the hoses. Kinked or crushed hoses restrict water flow and reduce pump performance. Inspect all hoses during installation and ensure they are routed properly without sharp bends. Replace any damaged hoses.

This assembly includes both pump and motor. The W11612326 is a complete pump and motor unit—you cannot replace just the motor or just the pump. If either component fails, the entire assembly must be replaced.

Verify the correct replacement for your model. The W11612326 replaces three older models (W10805386, W10879262, W11521435). Always verify your dishwasher model number matches one of the compatible models before ordering to ensure proper fit and function.

Monitor the first few cycles. After installing the new pump, run several wash cycles and monitor for leaks, unusual noises, or inadequate water pressure. Address any issues immediately before they cause further damage.
