euhomy ice maker making tiny ice slivers instead of full bullets, what am i doing wrong?

Diagnosis

The production of "ice slivers" or "crumb ice" in the Euhomy IM-02 is almost always caused by a premature trigger of the harvest cycle. The machine uses a temperature-sensing probe (thermistor) to determine when the water has frozen into solid bullets. If this probe is coated in mineral scale or calcium deposits—common in hard water areas—it creates an insulating layer. This insulation prevents the probe from accurately reading the actual temperature of the ice, tricking the control board into thinking the ice is ready for ejection long before the bullets have actually solidified.

Another primary cause is improper water-to-coolant ratios or insufficient airflow. If the internal condenser coils are clogged with dust, the refrigerant cannot dissipate heat efficiently. This leads to a "weak" freeze where the outer shell of the ice forms, but the core remains liquid. When the machine enters the harvest phase to push the ice out, the unsupported liquid centers collapse, resulting in thin, shattered slivers rather than the signature bullet shape. You can confirm this by checking if the ice slivers feel "slushy" or if the machine is cycling through the harvest phase significantly faster than the usual 7-15 minute window.

How to Fix It

To resolve this, you must perform a deep clean of the sensing mechanism and a system reset to recalibrate the temperature thresholds.

1. Unplug the unit from the wall outlet and remove the ice basket and any remaining ice slivers.
2. Open the top lid and locate the silver metal probe arm (the evaporator sensor) protruding into the ice-forming mold area.
3. Prepare a solution of 50% distilled white vinegar and 50% warm water. Dip a microfiber cloth or a cotton swab into the solution.
4. Gently scrub the metal probe and the surrounding aluminum walls of the freezing chamber. Focus specifically on any white, chalky buildup. This mineral scale is what causes the sensor lag.
5. Rinse the area by pouring a small amount of distilled water over the probe and wiping it dry with a lint-free cloth.
6. Drain the reservoir completely using the plug at the bottom to remove any sediment that may be interfering with water flow.
7. Refill the reservoir with filtered water (do not use tap water for this test) and plug the unit back in.
8. Press the "Reset" button if your specific sub-model has one, or simply power cycle the unit by leaving it off for 10 minutes before starting a new cycle.

If That Didn't Work

• Check the Ambient Temperature: The IM-02 requires a specific operating environment. If the machine is placed in a hot garage or too close to a wall (less than 4 inches of clearance), the condenser cannot breathe. Move the unit to a cool, open area and see if the bullet density improves.
• Perform a Full Descaling Cycle: Fill the reservoir with a commercial descaling solution or a high-concentration vinegar mix. Run two full ice-making cycles and discard all the ice produced. This cleans the internal piping and the pump, ensuring the water is distributed evenly across the freezing pins.
• Inspect the Water Level Sensor: If the water isn't filling the mold completely, you'll get thin ice. Ensure the float switch (the small plastic piece that moves up and down) isn't stuck due to slime or mineral buildup. Gently wiggle it to ensure it moves freely.
• Adjust Water Temperature: If you are using lukewarm water, the machine will struggle to hit the freezing point quickly, often leading to irregular shapes. Use chilled, filtered water to reduce the load on the compressor.

Heads Up

• Avoid using distilled water exclusively for long periods; while it prevents scale, the lack of minerals can occasionally affect the heat transfer efficiency of certain sensors. Use a filtered pitcher instead.
• Never use abrasive scrubbers or steel wool on the silver probe or the aluminum mold, as scratching the surface creates microscopic pits where bacteria and minerals can accumulate faster.
• Clean the external air vents every 30 days using a vacuum or compressed air to prevent the compressor from overheating, which is the leading cause of "thin" ice.
• Always empty the water reservoir every 24 hours to prevent the growth of biofilm, which can clog the small apertures where water enters the freezing chamber.
