What should I do if there are suds in the dishwasher tub?

Suds are caused by using incorrect detergent — only automatic dishwasher detergents should be used. To remove suds, open the dishwasher and let them evaporate, then add 1 gallon of cold water to the tub, close and latch the door, and pump out the water by slowly turning the dial to a drain period. Repeat the process if necessary. (Page 20)
