Ice cubes are too large or thick, may jam in the ejector or bin

Safety first: Unplug the unit and close the water supply tap before inspecting the valve.

Steps to check:

• Reduce cube size: If your Grundig model has a cube thickness control, lower the setting and monitor the next few batches.
• Test inlet valve: With water off and hose removed, check for drips from the valve outlet. Any leakage without power indicates a stuck valve that must be replaced.
• Clean flow meter: If fitted, remove and rinse the water flow meter to ensure accurate volume measurement.
• Inspect thermistor: Verify the evaporator sensor is firmly attached to the plate and not hanging loose, which can cause over-freezing.
