Jura Capresso-Impressa C-E-F-S-X Brew Group Drain Valve
The Drain Valve(Part #842) is located at the bottom of the Brew Group. Often times the O-Rings deteriorate or crack, causing the Drain Valve to leak. You will notice a decrease in coffee flow and increase in water accumulation in the Drip Tray. If there is no visible physical damage to the valve, then item #10198 (Drain Valve Repair Kit) is a cheaper alternative to fixing the leak; however, replacing the whole valve is simpler and ensures the leak will be fixed. To replace the Drainage Valve the Brew Group needs to be removed. Then, remove the side panels of the Brew Group, which are secured by locking tabs, to access the Drain Valve.
The brew group drain valve may become clogged with scale, preventing the flow of water from reaching the coffee grounds inside the brew group. In this case, dry grounds will be dispensed in the grounds container and no coffee is dispensed. The white cap attached the the metal rod may crack with extended use, or the spring becomes corroded and unable to compress. Either scenario will cause a portion or all of the water to drain into the drip tray during the brew cycle.
