E11 error, ice cubes are very small or hollow, unit reports water flow issue

Safety: Turn off water and power before disconnecting any water lines.

Steps:

• Check external filter: If your Neff ice maker uses an external or internal water filter, replace it if it is older than the recommended interval.
• Verify pressure: Ensure the supply tap is fully open and that other taps in the home have normal pressure.
• Inspect flow meter: Locate the flow meter (often integrated with the inlet assembly). Check for kinks or debris in the line leading to it.
• Flush system: After reassembly, run a few cycles to flush air and debris.

Resolution: If E11 persists and water flow is visibly weak only at the ice maker, replace the flow meter or the combined inlet/flow assembly as specified by Neff.
