Ice cubes are very small, hollow, or irregular; E08 water flow error may appear

Safety: Turn off water supply and disconnect power before disassembling water components.

Improving water flow:

• Replace external filter: If your Siemens ice maker is connected to a separate water filter, replace the cartridge according to the schedule or sooner if flow is weak.
• Clean inlet screen: Disconnect the supply hose and clean the mesh screen in the inlet valve as described for E04.
• Descale internal lines: Mineral buildup can restrict flow. Follow Siemens-approved descaling procedures using a food-safe descaler. Circulate the solution through the water circuit if the model supports cleaning mode.
• Check pressure: Confirm adequate water pressure at the supply. If using a long or narrow hose, consider replacing it with a standard Siemens-approved hose to reduce restriction.

After maintenance: Run and discard the first 1–2 batches of ice to remove any residual descaler or debris.
