What's Happening

The ice maker motor or sensor has a problem. Not to be confused with E15 on Bosch dishwashers (water in base). On refrigerators, E15 specifically relates to the ice maker mechanism failing to cycle properly.

How to Fix It

Check that the ice maker is turned on, the water supply is connected, and the freezer is cold enough for ice production (-4°F or below). If all checks pass, the ice maker assembly may need replacement.
