How do I remove suds from the tub if I accidentally used the wrong detergent?

Open the dishwasher and let suds evaporate, then add 1 gallon of cold water to the tub. Close and latch the dishwasher, then pump out the water by pressing the START/RESET pad and immediately pressing it again. Repeat if necessary, and in the future use only automatic dishwasher detergents such as Cascade® or Electrasol®. (Page 12)
