Dust enters the water pump. Jintaichang is a foot bath brand under Shanghai Taichang Health Technology Co., Ltd. Compared with its sister brand Hongtaichang, Jintaichang takes a physical marketing route, with higher advertising investment and more expensive pricing. Jin Taichang's healthy foot bath always drips when surfing and heating because dirt enters the water pump, trapping the motor blades and causing the foot bath to burn. Therefore, you should always clean the filter after soaking your feet.
