Your Jura coffee machine was built to last; however, it will need a tune-up from time-to-time. Even a Porsche has a limited number of miles before it needs a turn up. The brew group, which is the "engine" of the coffee machine, needs to be refurbished every 1-2 years, depending upon usage, to keep your Jura coffee machine operating at its peak capacity, and to avoid any larger issues.
