Ice maker not producing any ice, no error code displayed, unit appears to run

Safety: Always disconnect power and close the water supply before removing covers or panels.

Systematic checks:

• Check temperature: Verify the ice compartment is at the correct setpoint (typically around -18°C to -10°C depending on model). If too warm, investigate cooling issues (fan, condenser, door seal).
• Confirm water supply: Ensure the shutoff valve is open and the hose is not kinked. Test flow at the hose end.
• Inspect ice maker module: Look for obvious damage, broken gears, or ice jams. If the tray never fills with water, suspect the inlet valve or control board. If it fills but never harvests, suspect the ice maker module.
• Check bin sensor: Clean and test the bin level sensor or mechanical switch. If it falsely reads "full", the unit will not produce ice.

If basic checks fail: Replace the Siemens ice maker assembly as a complete unit, as this often resolves non-specific no-ice faults.
