Frequently Asked Questions
Common questions about GE C2 error
The C2 error on the GE GDT635HSMSS means the dishwasher cannot drain water after the wash cycle completes. The most common cause is a clogged drain filter at the tub floor. This filter catches food debris and should be cleaned monthly. A blocked garbage disposal connection is the second most common cause.
Yes. GE recommends running the garbage disposal for 10 to 15 seconds before starting the dishwasher when they share a drain connection. This clears any food pulp that may have accumulated in the disposal, ensuring the dishwasher drain hose connection is clear and water can flow freely at the end of each wash cycle.
