GE dishwasher C1 error code
- Dishwasher
GE dishwasher C1 indicates the unit did not drain within the expected time. The fine filter in the tub bottom, a clogged air gap on the sink, and a drain hose without a proper high loop are the usual causes on GDT665 and similar models. C1 after a new install often traces to a garbage disposal knockout still in place.

How to fix C1
- Remove the bottom rack and twist out the fine filter — rinse debris from the mesh and sump.
- If you have an air gap on the sink, remove the cap and clear any blockage inside.
- Verify the drain hose loops up under the sink before dropping to the disposal or drain tailpiece.
- Run a rinse cycle. Listen for the drain pump — humming without flow suggests a jammed impeller.
- Replace the drain pump only if the path is clear and water still pools after the cycle.
Call a pro when: Call a pro if water leaks from the door after filter service or the pump runs continuously.
