Hi, you have this question in the wrong park of the site. But I did a quick google search and believe I may have found an answer for you. I'll copy and past what I found for you here. If this doesn't solve the issue you should probably repost this question

"In the spot where the soap dispenses, there is a very small plug which controls the flow which you need to gently pull out and release (not break off) in order to break the vacuum seal. This information is not included in the regular instructions, but rather is written on a small 2-inch square piece of paper in the box. I was getting very frustrated because I had "primed" the soap dispenser at least 30 times and nothing had come out. I noticed the small plug, and while looking through the box again found the small piece of paper with the additional instruction. After that, it worked great! I use a generic version of Soft Soap, and we find the lowest setting dispenses more than enough soap."
