检查机器是否倾倒放置，如无，需拆机检查电路板总
成倾倒元件是否失效、需要更换电路板
Check if the machine is placed upside down. If not,
dismantle the machine to check if the circuit board
assembly has failed and the circuit board needs to be
replaced

检查机器是否处于非正常工作状态（倾倒、对墙、进
出风口被堵住等），将机器恢复至正常状态后重新插
电正常工作
Check whether the machine is in abnormal working
state (dumping, wall, air inlet and outlet are blocked,
etc.), restore the machine to normal state and then
replug it into normal working state
