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

Only use detergents specifically designed for automatic dishwashers, as sudsing detergents will cause overfoaming and can lead to leaking. To remove existing suds, open the dishwasher door and let the suds 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 control dial to a drain period. Repeat if necessary. (Page 14)
