GE Dishwasher Control Board Green Light: What It Means

Quick Answer

On GE dishwashers, a solid green light on the control board or panel typically means the machine is powered on and the door is locked or a cycle is active. A flashing green light during a cycle is normal and indicates cycle progress. A green light that stays on after a cycle ends with no error code is usually the Clean light indicating the cycle completed successfully.
