CRITICAL SAFETY WARNING: This repair involves working with electrical components and water connections in a dishwasher. Always disconnect power at the circuit breaker and turn off the water supply before beginning work to prevent electrical shock and water damage. If uncomfortable with this repair, hire a qualified technician.TOOLS REQUIRED: Phillips screwdriver, flathead screwdriver, adjustable pliers or channel locks, towels for water cleanup, flashlight, bucket or shallow pan, socket set or nut driver (optional), work gloves.

1. Disconnect power to the dishwasher at the circuit breaker panel. CRITICAL: Never work on the dishwasher while power is connected.
2. Turn off the water supply to the dishwasher at the shutoff valve under the sink. Turn valve clockwise to close.
3. Open the dishwasher door and remove all dish racks from the interior to provide access.
4. Remove any standing water from the bottom of the tub using a cup, sponge, or wet/dry vacuum. Important: The drain pump area will contain residual water.
5. Take multiple photos of the drain pump installation, hose connections, and electrical connections before disassembly. This is critical for proper reinstallation.
6. Remove the kickplate (toe panel) at the bottom front of the dishwasher by removing the mounting screws (typically 2-4 screws) or releasing the clips. Pull the kickplate forward and set aside.
7. Locate the drain pump in the base of the dishwasher (typically on the right side, connected to the sump with hoses and electrical wires).
8. Place towels and a shallow pan under the drain pump area to catch water spillage during hose removal.
9. Take detailed close-up photos of the drain pump from multiple angles, showing hose connections, electrical connections, and mounting position.
10. Disconnect the electrical connector from the drain pump by pulling the spade connectors straight off the two terminals. Do not pull on wires—grip the connectors. Note: Some models have a plug connector instead of individual spade terminals.
11. Disconnect the inlet hose from the drain pump by loosening the hose clamp with pliers or a screwdriver and sliding it back on the hose. Pull the hose straight off the pump inlet barb. Caution: Water will drain from the hose—direct into the pan.
12. Disconnect the outlet hose (drain hose) from the drain pump outlet by loosening the hose clamp and pulling the hose off the pump outlet barb. Caution: More water will drain—use towels to catch spillage.
13. Remove the drain pump mounting screws (typically 2-3 screws) that secure the pump to the dishwasher base or mounting bracket. Keep screws organized for reinstallation.
14. Carefully remove the old drain pump from the dishwasher base, maneuvering it out through the access opening. Set aside.
15. Inspect the old pump for visible damage: cracked housing, damaged impeller (look through inlet/outlet ports), corroded terminals, or signs of leaking. This confirms the diagnosis.
16. Test the old pump motor (optional) with a multimeter set to measure resistance (ohms). Touch probes to the two electrical terminals—should read approximately 100-200 ohms. Infinite reading = open circuit (failed motor winding). Very low reading (under 10 ohms) = shorted winding. This confirms motor failure.
17. Inspect the pump impeller by looking through the inlet port with a flashlight. The 9-vane impeller should be intact with no broken vanes, cracks, or foreign objects jamming it. Try rotating the impeller by inserting a screwdriver through the inlet—should spin freely with slight resistance. Seized or rough rotation = bearing failure.
18. Clean the pump mounting area on the dishwasher base, removing any debris, old gasket material, or water residue.
19. Inspect the hoses for damage, cracks, or deterioration. Replace hoses if damaged. Check hose clamps—replace if corroded or weak.
20. Inspect the electrical connectors for corrosion, damage, or burned terminals. Clean with electrical contact cleaner if necessary.
21. Unpack the new 00642239 drain pump from its packaging. Caution: Handle carefully—pump housing can crack if dropped.
22. Compare the new pump to the old one to verify dimensions, inlet/outlet port positions, mounting hole locations, electrical terminal configuration, and overall design match.
23. Inspect the new pump for any shipping damage before installation. Check housing, impeller (look through ports), terminals, and mounting bracket for integrity.
24. Test the new pump motor (optional) with a multimeter—should read approximately 100-200 ohms across terminals. This verifies the pump is good before installation.
25. Position the new drain pump in the mounting location on the dishwasher base, aligning the mounting holes with the screw holes in the base or bracket.
26. Install the pump mounting screws and tighten firmly but not excessively. Important: Do not overtighten—plastic housing or mounting bracket can crack. Hand-tight plus 1/4 turn is sufficient.
27. Verify the pump is securely mounted with no movement or play.
28. Connect the inlet hose to the drain pump inlet barb by pushing the hose firmly onto the barb until fully seated (typically 1-1.5 inches onto the barb).
29. Slide the inlet hose clamp forward over the hose-to-barb connection and tighten securely with pliers or a screwdriver. Important: Ensure the clamp is positioned over the hose and barb connection, not just on the hose. Loose clamps cause leaks.
30. Connect the outlet hose (drain hose) to the drain pump outlet barb by pushing the hose firmly onto the barb until fully seated.
31. Slide the outlet hose clamp forward over the connection and tighten securely. Verify the clamp is properly positioned.
32. Verify both hose connections are secure by gently tugging on each hose—should not pull off.
33. Reconnect the electrical connector to the drain pump by pushing the spade connectors firmly onto the two terminals until fully seated. Note: Drain pump motors are typically non-polar (either terminal can receive either wire), but maintaining original wire orientation is good practice.
34. Verify both electrical connections are secure by gently tugging on each connector—should not pull off.
35. Double-check all connections against your detailed photos to ensure correct installation: inlet hose, outlet hose, electrical wires, and mounting screws.
36. Clean up any spilled water from the dishwasher base with towels.
37. Reinstall the kickplate by positioning it and installing the mounting screws or engaging the clips. Ensure it's securely attached.
38. Reinstall the dish racks in the dishwasher interior.
39. Turn on the water supply to the dishwasher by turning the shutoff valve counterclockwise until fully open.
40. Restore electrical power at the circuit breaker panel.
41. Run a test cycle (rinse and hold or quick wash cycle, no dishes) to verify proper drain pump operation.
42. Listen for proper pump operation during the drain phase—should hear a smooth humming sound (not grinding, buzzing, or loud noise) for 1-3 minutes.
43. Verify the dishwasher drains completely—open the door after the drain phase and check that no water remains in the bottom of the tub.
44. Check for leaks under the dishwasher during and after the drain cycle. Inspect the pump area, hose connections, and floor around the dishwasher. Dry any residual water from installation.
45. Run a second test cycle (normal wash cycle with detergent, no dishes) to verify full operation including multiple drain cycles.
46. Monitor the drain cycles throughout the wash—the pump should operate smoothly during each drain phase with complete water evacuation.
47. Verify no error codes appear on the display panel. No error codes should appear if the pump is installed correctly and functioning properly.
48. Check for leaks again after the complete cycle. Inspect the pump area and all connections.
49. If the dishwasher drains properly with smooth pump operation, complete water evacuation, and no leaks, the repair is complete.

Safety Notes: Always disconnect power at the circuit breaker and turn off water supply before working on the dishwasher. Place towels and a pan under the pump area to catch water spillage during hose removal. Handle the new pump carefully—housing can crack if dropped. Ensure hose clamps are properly positioned and tightened to prevent leaks. Verify electrical connections are fully seated on terminals. Test operation thoroughly with multiple drain cycles. This repair requires moderate mechanical and electrical skills and typically takes 45-60 minutes for DIY.

1. The 00642239 features a 9-vane impeller design that provides superior water evacuation and debris handling compared to older 6-vane designs. The additional vanes increase pumping efficiency, reduce clogging from food particles, and provide smoother, quieter operation. This pump can handle food particles up to 1/4 inch without jamming, but larger objects (bones, fruit pits, glass) will damage the impeller and cause failure.
2. Always test the old pump motor with a multimeter before replacing to confirm motor failure versus a simple clog or wiring problem. Motor windings should read 100-200 ohms across terminals. Infinite reading = open winding (failed motor). Very low reading (under 10 ohms) = shorted winding. If resistance is correct, check for clogs in the pump impeller, inlet/outlet ports, or drain hose before replacing the pump.
3. Drain pump failures are often caused by foreign objects jamming the impeller—always inspect the sump area and pump inlet for debris before installing the new pump. Common culprits include broken glass, toothpicks, fruit pits, bones, twist ties, and small utensils that pass through the filter and enter the pump. Remove all debris from the sump and check the filter for damage. If debris caused the old pump to fail, address the source to prevent repeat failures.
4. Hose clamp position is critical—clamps must be positioned over both the hose and the barb connection, not just on the hose. Improperly positioned clamps allow the hose to slip off the barb under pressure, causing leaks and flooding. Position the clamp approximately 1/4 to 1/2 inch from the end of the hose, ensuring it compresses the hose against the barb. Tighten firmly but not excessively—overtightening can damage the hose.
5. If the new pump runs but doesn't drain water, check for kinked or clogged drain hoses, blocked air gap, or clogged garbage disposal connection. The pump can only evacuate water if the drain path is clear. Check the drain hose for kinks, loops below the dishwasher base (creates water trap), or clogs. If connected to a garbage disposal, ensure the knockout plug was removed from the disposal inlet. Check the air gap (if equipped) for clogs.
6. Bosch dishwashers use error codes E24 and E25 to indicate drain problems—E24 is drain timeout (pump runs but water doesn't drain), E25 is pump motor failure (pump won't run). E24 indicates a clog or drain path restriction, not necessarily pump failure. E25 indicates the control board can't run the pump motor (failed pump, wiring problem, or control board issue). Diagnose the specific error before replacing the pump to avoid unnecessary parts replacement.
7. The drain pump draws 0.6 amps at 120V (72 watts)—if the circuit breaker trips when the pump runs, there's a short circuit in the pump motor or wiring. A shorted motor draws excessive current and trips the breaker for safety. Test the new pump motor for shorts before installation: set multimeter to measure resistance, touch one probe to a terminal and the other to the pump housing (metal parts). Should read infinite resistance. Any reading indicates a short to ground—the pump is defective.
8. Drain pump noise (grinding, buzzing, humming) indicates bearing failure or impeller damage, not necessarily complete pump failure. A noisy pump may still drain water but is near the end of its lifespan. Bearing failure causes the impeller to rub against the housing, creating grinding noise and eventually seizing. Replace noisy pumps promptly—continued operation can damage the control board from excessive current draw.
9. Always run multiple test cycles after pump replacement to verify proper operation under various conditions. A single test cycle may not reveal intermittent problems, leaks, or performance issues. Run at least two complete cycles (one without dishes, one with dishes and detergent) to verify the pump operates reliably during all drain phases, drains completely each time, and doesn't leak.
10. The drain pump seal can fail from age, heat, and detergent exposure, causing water leaks from the pump housing. If your old pump shows water stains, corrosion, or visible leaking around the housing seam, the seal has failed. Seal failures are not repairable—the entire pump assembly must be replaced. Check for leaks during the first test cycle after installation to verify the new pump seal is intact.
11. If the dishwasher has been sitting with standing water for an extended period (days or weeks), the drain pump may be clogged with solidified detergent, food debris, or mold. Before replacing the pump, try manually clearing the impeller: disconnect power, remove the inlet hose, and use a screwdriver to manually rotate the impeller through the inlet port. If the impeller spins freely and the pump motor tests good with a multimeter, the pump may not need replacement—just cleaning.
12. Preventive maintenance significantly extends drain pump life—scrape dishes before loading, clean the filter monthly, and run a dishwasher cleaner cycle quarterly. Food debris is the leading cause of premature pump failure. Large particles clog the impeller, cause overheating, and damage bearings. Regular filter cleaning prevents debris from reaching the pump. Using a dishwasher cleaner removes detergent buildup and grease that can clog the pump and drain system.
