First, check whether the charging socket is inserted backwards or damaged, and try to replace it with a new one. Then check whether the power outlet is energized. If there is no electricity, it will lead to no charging. Then check whether the power cord is broken, whether the motor is damaged, and whether the control circuit is burnt out, and deal with it according to the specific situation.
Because the juicing cup is often in contact with liquids such as water and fruit juice, it is easy for the liquid to flow into the cabinet, resulting in short circuit of components on the control panel, so it is necessary to focus on checking the control panel.
Note that all equipment used must be original equipment. If not, it may be because the output power is low or the output power does not match that it cannot be charged. At the same time, pay attention to whether the components are installed correctly. If the components are not installed in place, it will also lead to the inability to charge. If you still can't charge the battery after the above inspection, it is that the hardware of the juice cup itself has problems and faults, which need to be sent to the after-sales maintenance station for professional maintenance.
