Diagnosis
You're getting 'crumb ice' because the freezing cycle is being interrupted too early, usually by a temperature sensor issue or a dirty component.
How to Fix It
The most likely culprit is the evaporator probe. Unplug the machine, open the top lid, and locate the silver metal probe arm inside the ice mold. Use a clean cloth dampened with white vinegar to wipe it down thoroughly—mineral buildup here fools the machine into ejecting ice before it's fully formed.
If That Didn't Work
Check that the machine isn't in a hot spot (next to an oven, in direct sun, or in a garage). The ambient temperature needs to be between 50-90°F for proper freezing. If it's too warm, it will cycle too fast and eject slush.
Heads Up
After cleaning, do a test cycle with a full water tank. It may take 2-3 cycles for the ice to return to normal size, so don't panic if the first batch is still small.
