the ice cubes are all stuck together in one big clump in the basket, they don't separate.

Diagnosis

The clumping or "bridging" effect in your DUMOS Ice Maker occurs because the unit is a non-refrigerated storage system. Unlike a full-sized freezer, the ice basket in this countertop model is simply a plastic bin sitting atop the cooling mechanism. Once the 9 bullet cubes are dropped from the freezing pins into the basket, they are no longer being actively frozen; they are merely resting in a humid environment. When the machine continues to run while the basket is nearly full, the newly dropped, freezing-cold cubes land on top of slightly melted cubes. This creates a "flash-freeze" effect where the thin layer of meltwater on the surface of the older cubes acts as a glue, fusing the entire batch into a single solid block. You can confirm this is happening if you notice a small pool of water at the bottom of the basket or if the ice feels "slushy" on the outside but hard in the center.

How to Fix It

To prevent the ice from fusing into a single mass, you must manage the thermal transition between the freezing pins and the storage basket. Follow these steps to maintain separate cubes:

1. Clear the Basket Frequently: Do not wait for the "Ice Full" indicator to trigger. Transfer the ice to a dedicated freezer container every 2 to 3 harvest cycles. This prevents the "stacking" effect where the weight of new ice compresses the melting ice below.
2. Optimize Cube Size: Select the "Small" cube setting. Small cubes freeze faster and have a different surface-area-to-volume ratio, which reduces the amount of surface melt that occurs during the drop sequence.
3. Pre-Chill Your Water: Fill the reservoir with chilled, filtered water rather than room-temperature tap water. This lowers the initial temperature of the water hitting the freezing pins, reducing the overall heat load inside the machine's chassis.
4. Ensure Proper Ventilation: Place the unit at least 6 inches away from walls or other appliances. If the condenser coils on the sides of the DUMOS unit cannot dissipate heat, the internal temperature rises, causing the ice in the basket to melt faster and clump more aggressively.
5. The "Shake" Method: Every 30 minutes, gently shake the ice basket or use the included scoop to stir the cubes. This breaks any early surface bonds and allows air to circulate between the cubes.

If That Didn't Work

• Check the Water Filter/Mineral Build-up: If you have hard water, calcium deposits can form on the freezing pins. This causes the cubes to drop unevenly or stick to the pins momentarily, resulting in "wet" cubes that clump instantly upon hitting the basket. Run a cleaning cycle using a 50/50 mixture of white vinegar and warm water to strip the mineral scale.
• Verify Ambient Room Temperature: If the machine is operating in a room above 80°F (27°C), the plastic basket will absorb ambient heat rapidly. Move the machine to a cooler area of the kitchen, away from the oven or dishwasher, to slow the melting process.
• Inspect the Lid Seal: Check the plastic rim of the lid for any gaps or warping. If the lid isn't sealing correctly, warm air enters the basket constantly, accelerating the melt-refreeze cycle that causes bridging.
• Reduce Duty Cycle: Turn the machine off for an hour if you have already filled a large freezer bin. Overworking the compressor can cause it to run hot, which radiates heat upward into the ice basket.

Heads Up

• Avoid Overfilling: Never force more ice into the basket than the "Full" line indicates; this puts pressure on the cubes at the bottom, forcing them to fuse together.
• Storage Warning: Never store ice in the DUMOS basket overnight. Because it is not a freezer, the ice will melt and re-freeze into a solid block of ice that can potentially damage the plastic basket walls.
• Cleaning Tip: Always dry the interior of the basket completely after a cleaning cycle. Residual water droplets will act as "nucleation points" for the first batch of ice, causing the first few cubes to stick to the walls.
• Water Quality: Use distilled or filtered water to prevent the "cloudy" ice effect, which is often accompanied by a higher rate of clumping due to dissolved minerals.
