It has some residues inside. I has got your problem. The pump is noisy. The copper side is not cold. People say that leaving it for half an hour, it will clear up bubble. But after half an hour, the copper side is hotter than before.
After a few months later, I took it apart. I discover a lot of residues "stones". Just like kidney stone. Those stones can be squeezed with fingers to power like stuff.
I used water pump to flush it. It comes out lots lots of stones.
Then I asked C hing in this forum how to refill it.. They are very helpful. |
