1 pack of Sanitation should do for the whole machine. If you keep turning the clean cycle off before the timer runs out, it is going to give you a clean runtime error. Also you didn't show how to put the product back into the machine. The water has to flow out if the product is not a dole and you shouldn't have to run sanitation through it twice.
What do I do if it says "error 5 cylinder sensor "? How do I fix it. Tried turning it off them back on several times. I've even removed everything, and put it back several times to try to fix this.
