Simpson warranty for pressure washers
The short version
Simpson doesn't cover everything, but keeps pump and components and accessories covered to 2 years. That full coverage is the same as most of the 5 brands we compared, which typically cover nothing in full. You don't need to register to get this coverage.
From Simpson's published warranty, checked October 2026.
