GE Dishwasher Drain Pump Replacement — What This Part Does
The drain pump forces water out of the dishwasher tub through the drain hose and into your home’s drain system or garbage disposal. It runs at the end of each cycle and between fill cycles to remove dirty wash water. The pump sits in the sump assembly at the bottom of the tub and uses an impeller to move water under pressure.
Pumps fail when debris jams the impeller, when the motor windings burn out, or when the impeller blades crack from age or impact. A clogged drain hose, a forgotten garbage disposal knockout plug, or a blocked filter can mimic pump failure, so always check the drain path before ordering a new pump.
Signs It Needs Replacing
- Standing water in the tub after a cycle Water remains at the bottom of the dishwasher because the pump is not moving it out through the drain hose.
- FED or FTD fault code on the control panel The dishwasher detects that water is not draining properly and triggers a drain-related fault code.
- Pump hums or buzzes but no water drains The motor tries to run but the impeller is jammed with debris or the motor itself is failing under load.
- Drain cycle starts then stops immediately The control sends power to the pump but the pump does not spin or draw enough current to complete the drain.
- Grinding or rattling noise during drain A damaged impeller blade or a foreign object trapped in the pump housing creates mechanical noise as the impeller tries to turn.
- No noise at all during the drain cycle The pump receives no power due to a wiring problem or the pump motor windings are electrically open.
How to Replace It
- Unplug the dishwasher from the wall outlet or switch off the circuit breaker, and turn off the water supply valve under the sink if you need to pull the unit out.
- Check the drain hose under the sink for kinks, clogs, or damage, and confirm the garbage disposal knockout plug has been removed if the dishwasher drains through a disposal.
- Remove the bottom dish rack and unscrew or lift out the filter assembly, then clean any debris from the sump area and float (if present).
- Remove the lower access panel or kick plate at the front of the dishwasher to expose the pump assembly underneath the tub.
- Disconnect the wire harness connector from the drain pump, then rotate the pump about a quarter turn counterclockwise and pull it down and out of the sump housing.
- Inspect the old pump impeller for debris or damage, and use a multimeter to check pump resistance (typical range is 15 to 40 ohms on many GE models, but this varies by pump family).
- Install the new drain pump by aligning the tabs with the sump opening, pushing up into place, and rotating a quarter turn clockwise to lock it in.
- Reconnect the electrical connector to the pump, making sure the latch clicks securely.
- Reattach the lower access panel, replace the filter assembly and bottom rack, restore power and water, and run a short drain or rinse cycle to verify the pump empties the tub and check for leaks around the pump and hose connections.

When to Call a Pro
If you find 120 volts at the pump connector during the drain cycle but the new pump still does not run, or if the dishwasher throws the same fault code after you have replaced the pump and verified the drain path is clear, the problem lies in the control board, wiring harness, or a pressure sensor. Electrical diagnostics and board-level repairs are best handled by a qualified appliance technician. Also call a pro if you are not comfortable working with 120-volt wiring or if your dishwasher is hardwired and you cannot safely disconnect power at the breaker.
