Jura brew group repair/rebuild kit, 11 pieces. When the Jura espresso machine displays Error 8, then brew group piston o-rings need to be replaced. Oval head tool is sold separately. All parts in the tune up kit are OEM ordered from the factory in Switzerland. Genuine OEM parts ensure best performance. This kit is used exclusively in our repair shop to rebuild the brew groups in JURA coffee machines that come in for repairs.
Jura brew unit should be rebuilt every 2 years for best possible coffee extraction. Failure to do so results in poor tasting coffee quality and flavor. Replacing the crema valve with spring and filter screen ensures that you get the best tasting coffee from your brew group, just like the new one. You will be glad you replaced them! The small dents on the filter screen causes channeling. New crema valve with spring ensures that 9 bars of hot water pressure is built for brewing perfect espresso.
Rebuilding the brew unit is a time consuming effort that can take up to 2 hours for end users who do not professionally repair the brew unit. In such cases, we suggest replacing the complete brew unit assembly for easy plug and play installation. Keep the old brew unit and rebuild it using this tune up kit. Use that as back up brew unit when you need it in future. CLICK HERE to check the price of the new brew group.
