How to check the error log
GE does not publish a consumer diagnostic-mode sequence for its dishwashers. Service-mode entry differs by model and lives in the technical service manual for your model number (printed on the tub or door edge). Button sequences circulating online are model-specific and often wrong, and service mode can run pumps, valves and heaters, so we do not list them. GE's own reset is: Start/Reset, wait two minutes, then switch off at the breaker for about 30 seconds.
Clear the log after a repair so you can tell whether the fault has really gone.
Beyond the fix
Tips and tricks
- Load so tall pots and handles do not touch the cup. GE says a flip-up cover normally opens about 45 degrees against the upper rack.manufacturer manual
- Wipe out old detergent residue from the cup before adding new detergent.manufacturer manual
- Make sure pods or tablets are not jamming the cover so it can open.manufacturer manual
Common mistakes
- Stacking dishes that block the cup, then blaming the dispenser.

Questions
What does C8 mean on the GE Appliances dishwasher?
Detergent cup blocked / dispenser did not open (on some models: water still too cold). The dispenser door could not open, usually because a dish or pan is in front of it, or dried detergent has jammed the latch.
Can I fix C8 myself?
DIY difficulty: easy. Load so nothing blocks the dispenser door. Clean the dispenser and latch with hot water.
How much does it cost to fix C8?
Part prices are not published by the manufacturer. Ask a parts supplier or service centre for a current price. Service prices vary by region and are not published by the manufacturer. Ask an authorised service agent for a quote before booking a visit.
Is it worth repairing?
Yes.
When does C8 typically show up?
GE Appliances dishwashers report C8 any. That timing is a useful clue when narrowing the cause.
Can I keep using the machine with C8 showing?
Generally yes — C8 is more of an annoyance than an emergency. Fix it when convenient; just do not let the cause sit for months.
Will C8 clear on its own?
Often, yes. The first step (load so nothing blocks the dispenser door) clears a share of cases on its own. If the code comes straight back, the part is genuinely at fault.
How long does the repair take?
Fifteen to thirty minutes with basic tools, once you have the part.
