E15 error; internal memory or configuration error, unit may reset repeatedly or lose settings.

Safety first: Disconnect power before accessing the control board.

• Power cycle the unit: Unplug the ice maker for at least 5 minutes to allow capacitors to discharge, then plug back in and observe if E15 clears.
• Check for surge damage: Remove the control board cover and inspect for burn marks, swollen components, or a burnt smell.
• Verify stable power: Use a surge protector or line conditioner if your mains supply is unstable. Avoid sharing the outlet with heavy appliances.
• Factory reset: If the Weasy model supports it, perform a factory reset using the button combination described in the user manual.
• Replace the main control board if E15 persists after reset and there are signs of board damage or corrupted memory.
