Official support and model manuals
Use the full model number from the rating label. The manufacturer manual is the deciding reference when codes differ by region or product family.
Frequently asked questions
What does C8 mean on a GE Appliances dishwasher?
On many model families, C8 indicates that the detergent dispenser did not open. Confirm the exact model and region because the same display can be used differently.
Can I clear C8 by unplugging the dishwasher?
A short power reset may clear a temporary state, but it will not fix a blocked hose, leak, failed sensor, motor, heater, or wiring fault. Stop if the code returns.
Should I replace a part based only on the code?
No. A code identifies a system or condition, not always the failed component. Complete safe external checks and use the model-specific manual or qualified service.
