E10 error; water tank or reservoir is detected as empty even when filled, or unit stops with 'Add Water' indication.

Safety first: Unplug the ice maker before removing the water reservoir or internal covers.

• Verify water level: Confirm the reservoir is filled to the correct mark with clean water.
• Locate the level sensor: On Weasy countertop models, a float and magnetic reed switch are often built into the reservoir or base. On built-in models, an electronic level sensor may be mounted in the tank.
• Inspect the float: Remove the reservoir (if removable) and check that the float moves freely up and down. Clean any scale or slime with warm soapy water and rinse thoroughly.
• Check the sensor: For reed switch types, use a magnet to actuate the switch and test continuity with a multimeter. For electronic sensors, inspect for corrosion and ensure the connector is firmly seated.
• Clean sensor area: Remove mineral deposits from the float guide tube and sensor housing using a vinegar solution.
• Replace the water level sensor or float assembly if it fails continuity tests or remains stuck despite cleaning.
