Services Unlimited, Inc./ Parts Guru 209 Walnut street, Lansdale, PA 19446 Phone: 215-362-7000 Fax: 215-361-7434 email: sales@partsguru.com This Jura brew group refurbishing instruction guide does not suddenly make anyone an instant expert. Please make notes of your own for every step to separate the parts and wires. Tag the parts mark locations and even take pictures after every three or four steps. We cannot provide help for reassembling the brew group. Refurbisjhing Jura Brew group is a precision work. Those who undertake this project have to be experienced in mechanical work. No responsibility is accepted for errors or damage to brew group or any injuries during repairs. These instructions apply to all Jura brew groups. Although the drainage valve, located at the bottom of each group, may differ slightly based on the espresso machine model, the fundamental structure and design of the all the Jura brew groups are identical. 1. Jura brew group in the upright position. Ensure the espresso dispensing tube connector is removed completely. Also, disconnect the hot water silicone/teflon tube to the brew group from the thermo block. Remove the brew group from the machine and place it on an open table or area before disassembling it. Disassembling the brew group is the easy part. However, reassembling can be challenging for the first time users. We therefore recommend taking pictures or shop.partsguru.co
Jura machines are made by Eugster/Frismag AG. in Switzerland, Portugal & in China. Jura as marketing Company does not share technical help or sell parts. We at Parts Guru sell parts, repair or trade in Jura machines.

Video guides show how to open-close machine, replace grinder, Brew group, tune up the machine & more! Jura Water filters are Expensive & Ineffective. Calcium deposits are seen in every Jura machine opened for repairs. Calcium deposits inside the machine cause the following problems: 1- Reduces flow of water with partial or total clogging; 2- Generate back pressure; 3- reduce pump pressure; 4- reduce flow of coffee in the cup; 5- Re-direct water for coffee into the drain tray; 6- Display error sign "Fill water tank"; 7- Paralyze the machine for expensive repairs. Descaling is best done manually every two or three months, without waiting for misleading reminders programmed in the Jura machine based on number of coffees served and not based on Calcium contents in water in different locations. CLICK HERE to Order Best descaler (#DSC-6) and follow authentic descaling process. Jura does not sell parts. There are frustrated Jura owners all over the World. The feedback below describes it well: I am writing from Australia, as I own a Jura Impressa J5 machine that has split the reinforced silicone hose joining the check valve down the bottom of the machine to the thermoblock up the top right hand side of the machine. As you would know Jura won't help me at all (they helped empty AU $2000 from my bank account when I purchased the machine), and won't even discuss alternate options other than sending the machine to them with $500 so they can replace a $20 hose for me. Can you advise an alternate way of fixing it, as I can access silicone hose the same size, but cant find reinforced silicone that size anywhere in Australia. Look forward to your reply Regards, Graham.
