InSinkErator warranty for water filters & dispensers
The short version
InSinkErator covers water filters & dispensers in full for 1 year, with no partial coverage after that. That full coverage is longer than most of the 29 brands we compared, which typically cover nothing in full. You don't need to register to get this coverage.
From InSinkErator's published warranty, checked October 2026.
