Sorry for the delayed reply as we were going through some analysis of the issue you have encountered. First of all, I would like to explain a bit about the design of the HumminGuru Cleaner. The two holes on both sides of the water tank slot are designed to prevent water from leaking from the water basin to the machine internally (where the circuit board is located). If there is water that was accidentally poured into the fan ducts or rotation wheel slots, the water will not damage the internal components. Instead, it will flow through a specifically designed internal basin to the water tanks slots through the holes. With that said, we can confirm that your machine is not defective.
However, to remedy or mitigate the issue of water dripping during pouring, we would suggest ○○○○○-san pour water from the middle of the water basin. Avoid the two sides where the rotation wheels and fan ducts are located, because those are the areas where the water will easily flow through the internal basin to the water tank compartment.
