Why does the Joyoung Soymilk Machine dj13b-d68sg not respond when I press Quick Soymilk and then Start?

I just got this model, and it was really a joke when I first started using it. First of all, the manual said to plug in the power and press the start/cancel button for 3 seconds, the machine will automatically select the altitude. I couldn't complete this step at all. Because my altitude is normal. Secondly, after adding ingredients and water, after pressing the double thick soy milk and fast soy milk buttons, there is no need to touch the start button. The machine will automatically beat (heat first and then beat intermittently). If you press the select button to select the remaining function buttons, For example, with dry/wet soy milk, you have to touch the start button to start working. The original poster and I made the same mistake. There is no problem with the machine. I am still getting familiar with it

The manual of the machine is a bit messed up and contains many errors. For example, when pulping is completed, the machine’s alarm sound is beep beep beep beep beep. . . The corresponding function lights flash at the same time (this happens within 1 minute), and the pulping completion alarm prompt on the instruction manual is beep beep beep beep beep. . . . . , Damn it, I just started using it and thought the machine was broken
