Ice maker runs but no ice is produced; display shows E02 after some time.

Safety first: Unplug the ice maker and close the water supply valve before disconnecting any hoses.

Step-by-step checks:

• 1. Confirm water supply: Ensure the household shutoff valve feeding the ice maker is fully open. Check that other fixtures on the same line have normal pressure.
• 2. Inspect water line: Look for kinks, sharp bends, or crushed sections in the plastic or copper line. Straighten or replace as needed.
• 3. Check for freezing: If the unit is installed in a cold area, inspect the inlet line and internal tubing for ice blockage. Thaw gently with warm towels; do not use open flame.
• 4. Clean inlet screen: Remove the water line from the inlet valve at the back of the unit. Inside the valve port is a small mesh screen; remove debris with a soft brush and rinse.
• 5. Test inlet valve coil: With the valve disconnected and unit unplugged, measure coil resistance with a multimeter. Compare to the specification in the service manual. Replace the valve if the coil is open or shorted.
• 6. Replace water inlet valve: If water supply is good and the valve does not open when commanded (technician test mode), install a new Blomberg water inlet valve assembly.
