“Sold Out” Errors

[Charity Bott]

Hello I currently purchased a Aquafina soda machine, no stickers for make and model. so I’m hoping I can find some answers here.

when I bought the machine, all selections said sold out, when they weren’t. I change the fuse, 5 out of ten selections stated working. I also changed the sold out paddles that fixed on sold out button then another one came on. 
 

I am hoping to find other things to try before I hire a technician. 
Thank you.
