      My Espresso Shop's Warranty

      My Espresso Shop offers a one year warranty unless otherwise noted. Please see individual product pages for warranty lengths. Our warranty is provided by the manufacturer or distributor, depending on the brand. Please contact us if you have a warranty-related issue, and we will make the appropriate arrangements. Our warranty for home/domestic machines included parts and labor limited to manufacturer's defects (unless otherwise noted). Warranty for machines used for commercial purposes includes parts only limited to manufacturer's defects - this means that labor to make the repair is not covered under warranty (unless a labor warranty is purchased or provided). Our warranty period begins at the free on board shipping point, which means that the buyer takes ownership once the product leaves our shipping location.
