Does NOT work

I followed the instructions. I set it up. I added water and it won’t work. I did all the troubleshooting in the manual and still doesn’t work. I’m having a hard time getting in touch with the company. It’s taking them a while to get back to me. I’m afraid I might not be able to return the item within the required time.
