Jura Brew Group Repair – Full Overhaul, Cleaning & O-Ring Replacement | Fix Error 8

In this video, I completely overhaul a Jura brew group (universal brew unit, part #62100) that was causing an Error 8 message. The brew group was moving stiffly, so I fully disassembled it, cleaned every part in an ultrasonic cleaner, replaced and lubricated all O-rings and lip seals, and serviced the drainage valve attached to the brew unit.
This step-by-step Jura repair guide shows the full process, including how to disassemble, clean, lubricate, and reassemble the brew group for smooth operation. Perfect for fixing Jura Error 8 issues and restoring your coffee machine’s performance.
Applies to: Jura Impressa, Jura J-series, Jura Z-series, Jura E-series, Jura S-series, Jura F-series and other models using the universal brew group (62100).
Tools & materials used:
• Ultrasonic cleaner
• Food-grade silicone grease
• Replacement O-rings & lip seals
• Jura brew group drainage valve service kit
