1, no power. If the wall-breaking machine is not powered on, first check whether the lid of the mixing barrel is properly covered. It may be that the trigger lever of the safety switch is broken or the lid is not tightly covered. If the problem still exists, it may be the main engine problem, which needs to be disassembled for inspection.

2. Some buttons can't work normally after being turned on. This may be due to the water in the connecting socket between the machine base and the glass tube, the deformation of the metal plate in the jack or the failure of the temperature sensor in the glass tube.

3. After the power is turned on, it will operate normally without stirring or heating. It may be a problem with the heating pipe or the temperature fuse, so it is necessary to check the heating pipe and the temperature fuse.

4, only heating, not beating. This is usually a motor or relay problem, and long-term operation may lead to overheating damage of the motor.

5. The touch screen is out of order. Check whether the power supply circuit and 5V voltage are normal first, and then check the control panel.

6. For these faults, users should first check the power connection, batching status, cleaning and maintenance. If the problem persists, professional maintenance may be required.
