Ice cubes are too small or thin, melt quickly in drinks

Safety first: Turn off water and power before disconnecting hoses or sensors.

Steps to check:

• Check water pressure: Disconnect the inlet hose and run water into a bucket. Weak flow indicates a plumbing issue that must be corrected.
• Clean inlet screen: Remove and rinse the mesh filter at the Grundig water inlet valve to restore proper flow.
• Inspect water level sensor: Clean the float or electronic level sensor in the reservoir so it can detect the correct fill level.
• Adjust cube size (if available): Some models allow cube thickness adjustment via the control panel. Increase the thickness setting slightly and test.
