Unit powers on but stops mid-cycle and shows E2 on the display, sometimes accompanied by continuous beeping.

Safety: Disconnect the ice maker from power before opening the housing or removing the water tank.

Steps to resolve:

• Check water level: Ensure the reservoir is filled to the correct mark. Some Sencor models will show E2 if the water level is too low or if the tank is not seated properly.
• Inspect the float: Remove the water tank and locate the plastic float or level sensor assembly inside the reservoir. Move it up and down by hand. It should move freely without sticking. Clean any mineral deposits or slime with warm water and mild detergent.
• Verify tank seating: Reinstall the water tank firmly. Misalignment can prevent the magnetic float from triggering the reed switch.
• Check wiring and connector: Access the internal float switch or water level sensor wiring. Ensure the connector to the main PCB is secure and wires are not broken or pinched.
• Test the switch: With a multimeter set to continuity, test the float switch or reed sensor while moving the float. It should open and close reliably. Replace the water level sensor / float switch assembly if it does not change state.
• Control board check: If the sensor and wiring are good but E2 remains, the main control board may not be reading the signal correctly and may need replacement.
