First go up and see if there is a leak around the water pipe or on both sides of the water tank. If the water tank is leaking, most of the time it has already leaked. This is because the silicone ring ages. You just need to buy a rubber ring and replace it in one go. If the water tank leaks, it will be more annoying, but it is not incurable. someone who does argon arc welding (making aluminum alloy doors and windows) and asks them to use an electric drill to open the shell, remove the polyurethane insulation and repair the leak . Just buy some styrofoam and repair it, it's one hundred and ten yuan. If you go to the dealer and they can't fix it and you can't return it to the factory, you might as well do it yourself.
