Visually, there is no corrosion where there is water. When the current is turned on, it is found that there is no current for a while, and it is concluded that there is a short circuit. When I opened the drawing, I found that the 8690 pipe PU21 and the PU23 pipe were passages. I directly removed the hot short-circuit pipe PU21 and re-burned the machine, and it was normal.
