GE Dishwasher F9 Error Code: Drain Pump Issue — Causes & Fixes
On a GE dishwasher, F9 is reported as a drain fault: the control ran the drain pump and the water did not leave the sump in the time it allows. GE has not used one code list across every dishwasher it has built, and many of its models signal faults with lights rather than letters, so confirm the meaning against the technical sheet stored inside your machine before buying a part. Whatever the label, a GE dishwasher with dirty water standing in the tub at the end of a cycle has a drain problem, and the checks on this page are the right ones for it. Do not confuse it with F9 on a GE range or wall oven, where the same two characters point at the oven door lock instead.
If the reset didn't clear F9
A technician can come out and diagnose it, the same day when a window is open — $69 diagnostic, applied to the repair.

Which GE models show F9
GE dishwashers sold under the GE, GE Profile and Café names are built on related controls, but not every model has a display that can show a letter-and-number code; models with only indicator lights blink a pattern instead. On GE ranges and wall ovens, by contrast, F9 is the code for the door lock, the motorised latch that holds the door shut during self-clean: the lock did not reach the position the control expected. If the F9 you are seeing is on an oven, the drain advice below does not apply. Switch the range off at the breaker for a minute; if F9 returns or the door stays locked, the lock needs a technician.
Common causes
Filters in the tub floor blinded
GE dishwashers use a fine mesh filter in the tub floor, and many models add a removable coarse filter or a hard-food chopper below the spray arm. Grease, seeds, labels and glass blind the mesh or jam the chopper, and the drain slows past the time limit.
Drain hose crushed or silted
The hose runs along the side of the tub and under the sink. A crush where it passes the cabinet wall, or years of grease inside it, restricts the flow even when the outside looks fine.
Disposal, knockout plug or air gap
When the dishwasher drains into a disposal, a full disposal stops it, and a new disposal with its knockout plug still in place stops it completely. A countertop air gap can block under its cap and spill into the sink.
Drain pump or impeller
A jammed impeller usually hums; a failed motor is usually silent. In both cases the water stays where it is.
Drain check valve stuck
A one-way flapper stops dirty water flowing back from the sink. Stuck shut with grease, it leaves the pump pushing against a closed door.
What you can safely try
- Power off at the breaker. Switch off the dishwasher's breaker before reaching into the sump. Pieces of a broken glass often end up there, so wear gloves.
- Bail out the water and remove the filter. Scoop the sump dry with a cup and a sponge. Take out the lower rack and remove the filter; on some models it twists out, on others it lifts after releasing tabs. Wash the mesh with warm water and a soft brush.
- Look into the drain opening. With the filter out and a flashlight, check the opening the water drains through for glass, bones, labels or fruit stones. Remove only what you can reach without tools.
- Check the disposal and air gap. Run the disposal with cold water for a few seconds. On a newly fitted disposal, confirm the knockout plug was removed. Lift the air gap cap, if there is one, and clear the chamber.
- Restore power and test with a rinse. Refit the filter until it seats, turn the breaker on and run a rinse with the tub empty. A dry sump at the end means the drain path is clear; standing water means the pump, the valve or the hose.
When to call a professional
If the filter and sump are clean and the drain under the sink is clear but water still stands in the tub, the pump, the check valve or the hose has to come off. GE pumps sit under the tub and are reached by removing the kick plate or sliding the dishwasher out of its opening, with water and power connections close by. Call us. On a GE oven showing F9, call too: a door lock that stopped mid-travel can leave the oven door locked shut, and the lock is tested with the range pulled out and powered down.
What the technician tests
- What F9 means on this model. The technician reads the technical sheet, and the fault history where the model stores one, to confirm what the code means on that machine before any part is ordered.
- Pump run test. The drain pump is run on its own from the service cycle while the sump is watched; a pump that runs without moving water has a jam, one that does not run is tested electrically.
- Pump winding and wiring. The pump's resistance and the voltage reaching it are measured to separate a dead pump from a wiring or control fault.
- Check valve and hose. The flapper is opened and cleaned, and the hose is disconnected and flushed end to end.
What it costs
If you fix it yourself: $0 (cleaning the filter, clearing the disposal inlet and air gap).
With a technician: A fixed price after diagnosis, agreed before any work starts; the diagnostic fee is applied to the repair when you approve it.
Frequently asked questions
What does F9 mean on a GE dishwasher?
It is reported as a drain fault: the dishwasher could not empty the tub within the time allowed. Clean the filter in the tub floor and check the disposal, air gap and hose before suspecting the pump, and confirm the code on the technical sheet for your model.
What does F9 mean on a GE oven or range?
On GE ranges and wall ovens, F9 points at the door lock used for self-clean: the lock did not reach the position the control expected. Switch the range off at the breaker for a minute. If F9 returns, or the door stays locked, the lock assembly needs testing by a technician.
Can a clogged garbage disposal cause a GE F9 error?
Yes. If the dishwasher drains through the disposal and the disposal is full, the water has nowhere to go and the drain times out. Run the disposal with cold water before taking anything apart in the dishwasher.
Will a reset clear F9 on my GE dishwasher?
Switching the breaker off and on clears the message. If water is still standing in the sump, the code returns at the next drain, because the cause is physical. Use the reset to confirm the fault after cleaning, not as the fix.
