GE Dishwasher Error Codes: Full List & Fixes
GE dishwashers mostly use C-codes plus a few word codes like FTD and H2O. Some point to fixes you can do yourself, and others need a technician.
Check your model: Codes vary by model. Confirm in your manual.
Safety first: Unplug the appliance (or switch off its breaker) before you remove panels, filters or hoses. Turn off the water supply valves before you disconnect any hose, and keep a towel and shallow pan handy. Never work on wiring, gas lines or sealed refrigerator systems yourself.
