# GE dishwasher error code C8

### What C8 means, in the maker’s own words

The detergent cup is blocked from opening fully. One of the most satisfying codes on this appliance, because the cause is usually visible and the fix takes ten seconds.

### Where this code actually appears

On the control panel, and usually with a sound. GE describes their refrigerator codes as flashing green on the display and typically accompanied by a beeping, and the range, microwave and dishwasher tables all describe codes you can read from the front of the appliance. That is the opposite of some makes, where the number is written into a hidden log and never shown — here, if something is wrong, the appliance generally tells you. Photograph what it says before cutting the power, because a reset erases it and the code is most of the diagnosis.

### What to do about it

- Remove the obstruction — GE names silverware or a pan, which is exactly what it usually is.
- Close and latch the door and wait 30 seconds for the cup to open.
- If the cup still will not open with nothing in its way, the cup mechanism or its release is the repair, and it is a small one.

### Where this goes next

The job this usually becomes is [dishwasher door latch repair](/services/dishwasher-door-latch-repair/), and every one of those pages carries a starting figure and the reasons that move it. If it turns out to be nothing — and on this make a real share of these are modes rather than problems — the visit ends there and you pay the diagnostic and nothing else, or call [(305) 306-2503](tel:+13053062503) and describe what the display is doing before booking anything.
