You pay everything through the same corner machine. If paying with a card :
click on start button
Enter product number on the right
Insert card - if all 4 green lights turn on that means it took your card :)
(you find the number on each machine whether it's soap or washer or dryer.) Every machine has a number on it .
If paying cash - insert money first then click on the number to the right choosing the machine you are using
After go to the machine - for detergent go to machine and click on the number you want (white or color ) each pouch as two detergents :)
For washing machine put the detergent pod inside then your clothes, close and lock the handle. (I just used whatever setting it was on lol ) than click on the lighted button towards the bottom of all the settings in the washer that should be it :)
