What the warranties and owners say
What does each warranty actually cover?
Bosch’s manufacturer warranty, per bosch-home.com, covers the entire 800 Series dishwasher for parts and labor for one year. After that, coverage narrows: years two through five are parts-only for the microprocessor or printed circuit board and the upper or lower racks (rack components excluded), plus a lifetime parts-only guarantee against rust-through on the inner tub liner and stainless steel door. There’s no labor coverage past year one, but the five-year window on electronics and racks is longer than anything KitchenAid publishes for the whole unit.
KitchenAid’s own limited warranty for the KDTM404KPS (document W11655295A, linked from the model’s page on kitchenaid.com) covers factory-specified parts and labor for one year from the date the dishwasher is delivered. The extra two-year and five-year terms in that same document apply only to certain ranges, built-in refrigerators and ice makers, not to dishwashers. So after year one, a KitchenAid repair is fully on the owner, while a Bosch owner still has parts-only coverage on the electronics, the racks and rust-through.
On cost per year of warranty, both machines carry one year of full coverage, so the cheaper machine wins: the KitchenAid works out to $1,079 a year against $1,399 for the Bosch. If you plan to keep the dishwasher for many years, Bosch’s longer parts-only coverage is the main thing the extra $320 buys.
Bosch 800 Series Dishwasher vs KitchenAid KDTM404: questions buyers ask
Which dishwasher has the longer warranty?
Both come with one year of full parts and labor coverage. Bosch then adds parts-only coverage in years two through five for the microprocessor or circuit board and the racks, plus lifetime parts-only coverage against rust-through on the inner tub liner and the stainless steel door. KitchenAid’s current warranty for the KDTM404KPS adds no dishwasher coverage after the first year.
Does either warranty pay for labor after the first year?
No. Bosch’s coverage after year one is parts only, and KitchenAid’s dishwasher coverage ends after year one.
When does the KitchenAid warranty start, and where does it apply?
It runs from the date of delivery of the original purchase, and it is valid only in the United States and Canada for a dishwasher used in the country where it was bought.
