GE Dishwasher C8 error code
C8 means the detergent cup is blocked from opening fully. Something inside the tub is physically stopping the dispenser door from swinging open. Because detergent never releases, dishes will come out dirty even though the cycle runs.

What causes the C8 error?
- Tall silverware, a pan, or a utensil leaning against the dispenser door
- Dish loaded directly in front of the detergent cup
- Detergent residue gumming up the dispenser mechanism
