Other manufacturers also low water pressure and clogged filters as causes of small/hollow ice cubes

Possible Causes

Low water pressure to refrigerator water system

How to Identify: Slow dispenser flow, small or hollow ice cubes, occurs on both water dispensing and ice making.

Part: Water supply line / household water pressure

Clogged or old water filter reducing flow

Part: Water filter

Air in the water line

How to Identify: Spitting or sputtering water from dispenser; small/hollow ice cubes noted after recent filter changes or initial installation.

Part: Water supply line

Malfunctioning water inlet valve reducing fill volume

How to Identify: Ice maker not filling properly with water before freeze cycle, leading to small or hollow cubes.

Part: Water inlet valve

DIY Solutions

Check and increase household water pressure

Moderate 10-30 minutes

Confirm household water pressure meets refrigerator requirements (typically ~20 psi or higher).
Ensure water supply valve behind refrigerator is fully open.
If pressure is low, consider contacting plumber to increase pressure or verify supply line isn’t kinked.

⚠️ Safety First: Avoid forcing valves beyond their stop point

Easy 10-15 minutes

Tools Needed: Replacement water filter

Locate and remove existing water filter per KitchenAid instructions.
Install a new manufacturer‑approved filter.
Run 2–4 gallons of water through dispenser to flush air and debris.

⚠️ Safety First: Have bucket/towel ready for flushing

Purge air from water line

Easy 5-10 minutes
