Solution:
First of all, please check the installation status of the main pot. Please align the alignment arrow on the bottom of the main pot with the arrow on the main body of the device, so that there is no obvious gap between the main pot and the main pot, so as to ensure that the main pot is completely placed in place. Then press the lid fully to ensure that it is completely sealed with the mouth of the mixing bowl. Finally try to start cooking again.
