Is This the Right Part?

Confirm the complete model number before ordering. Similar drain pumps may differ in hose port orientation, electrical connector type, mounting tab positions, or impeller design.

Common Symptoms

• Dishwasher not draining — standing water in the bottom of the tub after the cycle
• Drain pump running but water not evacuating — impeller failed or jammed
• Loud grinding, humming, or rattling from the drain pump area during the drain cycle
• Error codes related to drainage (e.g. F8E1, F9E1, or equivalent model-specific drain fault codes)

Check Before Replacing

• Inspect and clean the drain filter and sump area for food debris, glass, or foreign objects jammed in the impeller before condemning the pump
• Check the drain hose for kinks, clogs, or improper high-loop installation that prevents gravity drainage
• Verify the drain solenoid or check valve (where applicable) is not the source of the blockage
• Confirm the control board is sending the drain signal — a failed board can prevent the pump from activating even if the pump itself is good

Installation Notes

1. Disconnect power and shut off water supply before beginning.
2. Photograph all hose connections, clamp positions, and wire harness routing before disconnecting.
3. Remove the dishwasher lower panel and tilt or pull the unit to access the pump from below, or access via the interior sump depending on model.
4. Compare the new pump with the original — confirm port positions, connector type, and mounting tabs match before installation.
5. Inspect nearby hoses, clamps, and the drain filter housing for wear or cracking while the pump is out.
6. Restore power, run a drain-only cycle, and check for leaks at all hose connections.

Use a qualified technician when diagnosis or installation is outside your experience.
