Food debris, broken glass, or grease accumulates in the drain sump at the bottom of the dishwasher. GE dishwashers have a fine filter and a coarse filter — both need regular cleaning.
The drain hose can become clogged with grease and food particles over time, especially if dishes aren't rinsed before loading. The hose connects to either the garbage disposal or an air gap under the sink.
The drain pump motor can burn out or the impeller can crack. If you hear humming but no draining, the motor is trying but failing. Complete silence during drain cycles indicates a dead motor.
GE dishwashers have a check valve that prevents backflow. If this valve gets stuck closed, water can't exit even with a working pump.
Remove the bottom rack, locate the filter assembly at the bottom center, twist to remove, and clean thoroughly under running water. Check the sump area for debris like broken glass or food particles.
Pull the dishwasher out, inspect the drain hose for kinks. Disconnect from the disposal/drain and flush with water. Replace if the hose is cracked or heavily clogged.
If connected to a disposal, run it for 30 seconds with water. A clogged disposal blocks dishwasher drainage.
Turn off the dishwasher at the breaker for 5 minutes. Restart and run a rinse cycle to test drainage.
If the filter is clean, hose is clear, and the error persists, the drain pump needs professional diagnosis. GE drain pumps are located under the dishwasher and require tipping the unit or removing the kick plate to access. A technician can test the pump motor electrically and replace it if needed. Also call a pro if you notice water leaking from under the dishwasher.

F9 indicates a drain pump error. The dishwasher couldn't drain water within the expected time. Start by cleaning the drain filter and checking the drain hose for clogs.
Turn off the dishwasher at the circuit breaker for 5 minutes, then restore power. If the error was a temporary glitch, it will clear. If it returns, there's a physical drainage issue.
Yes, absolutely. If your dishwasher drains through the garbage disposal and the disposal is clogged, water backs up and triggers the F9 error. Run the disposal for 30 seconds with water before troubleshooting the dishwasher.
