What type of detergent should I use in this washing machine?

You must use high efficiency (HE) detergent only, such as Tide HE, Wisk HE, Cheer HE or Gain HE. HE detergents contain suds suppressors that reduce or eliminate suds, allowing the load to tumble more efficiently and maximize cleaning. Do not use non-HE detergent, organic detergent, natural detergent, or HE detergents with natural ingredients like vinegar or baking soda.
