What does the GSD1120 warranty cover and for how long?

The dishwasher comes with a full one-year warranty covering parts and labor for manufacturing defects, and a limited second-year warranty covering replacement parts only (you pay labor). Additionally, there is a limited five-year warranty on racks that rust and electronic control module parts, and a full twenty-year warranty on the PermaTuf tub and door liner if it fails to contain water due to a manufacturing defect. The warranty does not cover improper installation, air gap cleaning, misuse, or damage from accidents, fire, or floods. (Page 16)
