Clean dishes start with better parts. And with the 2X Life tested motor and a 10-year limited parts warranty, this is an ENERGY STAR qualified dishwasher you can count on. There's no need to rinse off dried-on food thanks to the ToughScrub option and a powerful 4-blade stainless steel chopper. For even more cleaning power, the JetClean Plus Steam cycle blasts off food particles with high-pressure spray jets and then adds the finishing touch of steam to reduce spots. The Auto Clean Plus cycle also uses sensors that monitor soil levels to help get dishes clean. Plus, the 100% stainless steel tub looks great, fights corrosion and improves drying performance. This model is so quiet, if you are not completely satisfied that this dishwasher is quieter than your previous model, Whirlpool Corporation will take it back within 30 days of the purchase date and refund the full price to you. (Finance charges, removal of previous dishwasher and cost of installation are not covered by this guarantee.) Please see attached warranty, page 2, for details.
