E08 displayed, ice cubes are very small or thin, production is slow

Safety first: Close the water supply and unplug the unit before disconnecting any water lines.

Steps to improve water flow:

• Replace or clean water filter: If your De Dietrich ice maker has an internal water filter cartridge, replace it according to the manual. A clogged filter reduces flow.
• Inspect inlet valve screen: Remove the water line at the water inlet valve and clean the mesh screen of sediment.
• Check water distribution tube: Open the ice compartment and locate the water distribution tube or spray bar above the evaporator plate. Remove it if possible and soak in descaler to remove mineral deposits.
• Verify water pressure: Ensure the household supply provides adequate pressure (typically 1–10 bar). Very low pressure can cause small cubes.

After cleaning: Restore water and power, then run a few cycles. Discard the first batch of ice to remove any residual descaler or debris.
