Diagnosis
Internal leak. Water is escaping from a connection hose, the drain hole, or the ice mold assembly inside the cabinet.
How to Fix It
Immediately unplug and move the unit to an empty sink or towel-covered surface. Remove the water reservoir and ice basket. Tip the unit slightly to drain standing water from the bottom. The most common source is a disconnected or cracked drain tube from the ice mold. You'd need to open the rear panel (not user-friendly) to check. A more accessible check: ensure the rubber drain plug at the back is securely inserted—it can pop out.
If That Didn't Work
The ice mold itself might have a hairline crack from mineral expansion or impact. With the unit dry, pour a small amount of water directly into the mold cavity. If you see water seep from the bottom casing within a minute, the mold is compromised.
Heads Up
Continuing to run a leaking unit risks severe electrical damage and mold growth inside the machine. This is one of the few issues where if the external fixes don't stop it, professional repair or replacement is the only safe option.
