GE Dishwasher EF Error Code — What It Means
The EF error code is not published in GE’s official fault code list for dishwashers. When customers report ‘EF’ on a GE dishwasher, it often reflects a misread display or confusion with another brand’s codes. The actual GE code for drain faults is C3, which means the dishwasher will not drain. GE’s guidance for C3 directs you to reset power, inspect the float assembly in the front-left corner of the tub, clear the sump area at the back bottom of the tub, check the drain hose for kinks or blockage, and verify the air gap and disposal connection are clear. If your display shows something other than C3, write down the exact characters and your model number before troubleshooting, since the fix will depend on the true code.
Common Causes
- Stuck float cover The plastic float cover in the front-left corner of the tub floor can stick and prevent the dishwasher from recognizing proper water levels or drainage.
- Debris in sump area Food particles, glass, or other debris in the sump area at the back bottom of the tub will block the drain path and trigger a drain fault.
- Kinked or blocked drain hose The drain hose may be kinked, improperly routed, or clogged internally, preventing water from leaving the dishwasher.
- Clogged air gap If your installation includes an air gap on the countertop, blockage inside it will stop drainage and cause the code to appear.
- Clogged disposal connection When the dishwasher drains into a garbage disposal, a plugged disposal or un-knocked knockout plug will prevent water from draining.
Step-by-Step Fix
- Verify the exact code displayed on your dishwasher’s screen and locate your model number on the door jamb or inner edge to confirm whether it matches GE’s published codes.
- Disconnect power at the breaker or unplug the unit for 30 seconds, then restore power and start a new cycle to see if the fault clears.
- Tap the float cover in the front-left corner of the tub floor to unstick it, then lift the cover and inspect underneath for debris or damage.
- Remove the lower spray arm and inspect the sump area at the back bottom of the tub, clearing any food particles, broken glass, or other blockages you find.
- Check the drain hose under the sink for kinks, loops higher than the connection point, or internal clogs, and reposition or flush it as needed.
- Clean the air gap if your installation has one by removing the chrome cap on the countertop and flushing the interior with water.
- Run the garbage disposal if the dishwasher drains into it, and verify the knockout plug was removed when the dishwasher was installed.
- Contact GE service if the fault persists after all inspections, or if your display shows a code not listed in GE’s published documentation.

When to Call a Pro
Call a technician if the code reappears after you have reset power and verified the float, sump, drain hose, air gap, and disposal are all clear. Also call service immediately if your display shows a code that does not appear in GE’s published list, since you may need a control-board diagnostic or a model-specific repair bulletin. If you are not comfortable disconnecting the drain hose or accessing the sump area, a professional can complete the inspection safely and identify whether a pump, pressure switch, or wiring fault is involved.
