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

Safety first: Unplug before cleaning internal parts.

Step-by-step:

• Check water level: Fill the reservoir to the MAX line with cold water. Avoid using warm water.
• Clean evaporator: Wipe the evaporator fingers with a soft cloth and a little vinegar to remove film that can insulate the surface.
• Improve environment: Move the unit to a cooler room and away from heat sources.
• Run multiple cycles: Sometimes the first few batches are smaller; allow 2–3 cycles and compare ice size.

When to call a technician: If ice remains very small despite good water level and environment, the refrigeration system may be weak and needs professional evaluation.
