E5 error; ice maker may fill with water but fails to form or harvest ice properly.

Safety First: Turn off power and shut off the water supply to the Café ice maker before working on the water system.

Steps:

• Access water reservoir: Remove the front panel and locate the water reservoir or sump where water collects before being pumped over the evaporator.
• Inspect water level sensor: Many Café ice makers use metal probes or a float-type sensor. Look for mineral scale, slime, or debris on the probes or float.
• Clean sensor: Mix a solution of warm water and a small amount of ice machine cleaner or white vinegar. Wipe the probes or float thoroughly. Rinse with clean water and dry.
• Check wiring: Ensure the sensor harness is firmly connected to the main control board and not damaged.
• Test operation: Restore power and water, then run a cycle. If E5 returns, the sensor may be defective.
• Replace water level sensor: Remove any mounting screws or clips, disconnect the harness, install the new Café water level sensor, and reassemble.
• If still unresolved: The main control board may not be reading the sensor correctly and may need replacement.
