it's leaking water from the bottom onto my counter, not from the tank connection

Diagnosis

The leaking occurring from the bottom of the Antarctic Star AZ-I11A, specifically when it isn't coming from the reservoir connection, is typically caused by a failure in the internal water circulation loop or a breach in the chassis seal. Because this model uses a gravity-fed system paired with a small internal pump to move water over the evaporator plates, any vibration-induced loosening of the silicone tubing will result in water pooling at the base of the unit. The most common culprit is the primary discharge hose that connects the pump to the water distribution tray. Over time, the constant vibration of the compressor and pump can cause the tubing to slide off the plastic nipple or develop a hairline tear. Additionally, if the unit is not perfectly level, water can bypass the internal collection tray and seep through the bottom ventilation slats. You can confirm this by placing a piece of dry cardboard under the unit; if the wet spot is concentrated toward the rear-left corner, it is almost certainly a tubing or pump seal failure.

How to Fix It

To resolve this leak, you must access the internal plumbing. Follow these precise steps:

1. Unplug the AZ-I11A from the wall outlet and remove all ice from the basket to avoid spills.
2. Carefully tilt the unit backward at a 45-degree angle. Look at the bottom chassis through the ventilation gaps.
3. Locate the clear silicone tubing leading from the pump to the reservoir. Check for any gaps where the tube meets the plastic connector.
4. If the tube has slid off, push it firmly back onto the nipple. To ensure a permanent fix, use a small plastic zip-tie or a piece of heat-shrink tubing to cinch the hose tightly around the connector.
5. Check the pump gasket. If you see water dripping directly from the pump housing rather than the tube, use a small amount of food-grade silicone sealant around the pump's mounting flange to stop the seepage.
6. Wipe the bottom of the unit completely dry and place it on a level surface using a bubble level to ensure the unit is not tilted forward, which prevents water from pooling in the wrong area.

If That Didn't Work

• Inspect the Evaporator Tray: The plastic tray that holds the water for freezing can develop hairline cracks due to thermal expansion and contraction. If the leak persists, you will need to remove the outer casing screws to inspect the tray. If a crack is found, use a waterproof, food-safe epoxy to seal the breach.
• Clear the Drain Port: Mineral buildup from hard water can clog the return line, causing the internal tray to overflow. Use a pipe cleaner or a thin flexible wire to clear the drain hole at the bottom of the freezing chamber to ensure water flows freely back into the reservoir.
• Check the Pump Impeller: If the pump is struggling or "stuttering," it can create back-pressure that forces water out of the seals. Ensure no debris or ice shards are jammed in the pump impeller.
• Replace the Internal Seal: If the leak is originating from the pump's internal mechanical seal, the pump assembly (Part #AZ-PUMP-11) may need replacement, as these seals are not user-serviceable.

Heads Up

• Avoid Distilled Water: Using purely distilled water can actually lead to poor ice formation and unexpected drainage issues; use filtered water for the best balance of purity and machine longevity.
• Weekly Descaling: To prevent the clogs that lead to overflows and leaks, run a cycle of 50% white vinegar and 50% water through the machine every two weeks.
• Ventilation Clearance: Ensure there are at least 6 inches of open space around the sides and back of the unit. Overheating the compressor can warp the internal plastic housings, leading to leaks.
• Avoid Overfilling: Never fill the reservoir past the "MAX" line, as this can cause the pump to overflow the distribution tray during the initial priming phase.
