Ice maker produces ice, but cubes are very small or hollow.

Safety first: Unplug the unit before removing internal covers.

Steps to improve ice size:

• Check water level: Ensure the reservoir is filled to the MAX line with cool, clean water.
• Clean water distributor: Remove the ice basket and top inner cover to access the water distribution tray above the evaporator. Clean any mineral deposits from the holes or slots so water can flow evenly.
• Descale the system: Run a cleaning cycle using a mixture of water and white vinegar per the Silonn manual to remove internal scale that can restrict flow.
• Verify pump flow: During operation, observe water flowing over the evaporator. Weak or uneven flow may indicate a failing recirculation water pump.
• Improve ambient conditions: Move the ice maker to a cooler room away from direct sunlight or heat sources, as high ambient temperature reduces ice thickness.

When to call a professional: If water flow is good but ice remains thin, there may be a partial cooling issue requiring professional diagnosis.
