water is leaking from the bottom of my kismile ice maker, pooling on the counter.

Diagnosis

Water pooling at the base of the Kismile Nugget Ice Maker is typically caused by a failure in the internal drainage system rather than a breach in the primary water reservoir. In these units, melted ice and excess water are channeled through a silicone drainage line into a small internal pump, which then cycles the water back into the reservoir. When this line slips off the pump nozzle or develops a pinhole leak, water bypasses the collection system and drains directly into the machine's chassis, eventually leaking out from the bottom seams onto your countertop. You can confirm this by placing a dry paper towel under the machine and running a "Self-Cleaning" cycle. If the leak accelerates during the cleaning cycle or immediately after a batch of ice is harvested, the issue is almost certainly the drain tube connection. Another possibility is a hairline fracture in the pump housing, often caused by freezing if the machine was stored in a cold garage or if the internal temperature dropped too low, causing the stagnant water in the pump to expand and crack the plastic.

How to Fix It

To resolve a loose drain line or a minor pump misalignment, follow these precise steps:

1. Power down the unit and unplug it from the wall outlet. Remove the ice basket and empty all remaining ice and water from the internal chamber.
2. Carefully tilt the machine backward at a 45-degree angle. Locate the small white drain pump assembly situated near the base of the unit.
3. Identify the two clear silicone tubes: the intake tube (coming from the ice-making chamber) and the return tube (leading back to the reservoir).
4. Inspect the connection points. If a tube has slipped, push it firmly onto the plastic nozzle. To ensure a permanent seal, use a small, plastic cable tie (zip tie) around the tube and the nozzle, tightening it with pliers until the tube is compressed firmly against the plastic.
5. Check the return line for any kinks or folds that might be causing back-pressure, which often forces water out of the connection points. Straighten any bends using your fingers.
6. Right the machine, refill the reservoir with distilled water, and run one full "Self-Cleaning" cycle to verify that no water is escaping the base.

If That Didn't Work

• Inspect the Reservoir Seal: Check the gasket where the water reservoir meets the main body. If the gasket is pinched or has a piece of debris trapped in it, water can seep over the edge of the tank and run down the interior walls of the machine, mimicking a bottom leak. Wipe the seal clean with a damp cloth and reseat the tank firmly.
• Replace the Drain Pump: If you see a visible crack in the white plastic housing of the pump, the unit must be replaced. Search for a compatible 12V DC miniature diaphragm pump. You will need to disconnect the two electrical leads and swap the silicone tubing to the new pump.
• Clear the Ice Chamber Drain: Sometimes a small piece of "stray" nugget ice gets lodged in the drain hole at the bottom of the ice-making chamber. This causes water to overflow the internal basin and leak through the chassis. Use a flexible pipe cleaner or a thin plastic straw to gently probe the drain hole and clear any ice blockages.
• Check the Bottom Vent Seals: Ensure the rubber feet are seated correctly and that no external liquid has entered through the bottom vents. If the machine was accidentally tilted while full, water may be trapped in the internal insulation, which will continue to leak for several days. Leave the machine unplugged and tilted forward for 24 hours to air dry.

Heads Up

• Use Distilled Water: To prevent mineral buildup (scale) in the narrow drain tubes and pump, always use distilled or filtered water. Calcium deposits can narrow the tube diameter, increasing pressure and causing leaks.
• Avoid Extreme Temperatures: Never store this machine in a garage or shed during winter. If water freezes inside the pump housing, it will crack the plastic, leading to permanent leaking.
• Monthly Descaling: Run the self-cleaning cycle with a mixture of white vinegar and water once a month to keep the drainage lines clear of biofilm and slime.
• Level Surface: Ensure the machine is on a perfectly level surface. If the machine tilts, water may not flow correctly toward the drain pump, causing it to overflow the internal collection tray.
