Jura Impressa E4 - E8 (new models) brewing unit disassembly

Remove all attachments: Coffee ground container, trester drawer, water tank and the coffee beans.

Pull off the flap above the water tank to the rear.

At the very bottom of the back is a hurdle: two oval head screws, they look like rivets. They can be unscrewed with a special tool. At iFixit, the Oval Drive Bit is part of tool collections, you can also get it at law dealers or find it on the Internet. The manufacturer wants to make it more difficult for us!

Unscrew the two oval head screws.

The side panel on the water tank side is still attached with two Torx T15 screws. Unscrew them.

The two side panels are fixed at the bottom front with one Torx T15 screw each. Unscrew those.

Push the two side panels back a bit and pull them out at the bottom, then you can remove them. Do not remove the side panel with the power switch completely yet.

Turn the power switch a little clockwise and remove it.

Pull off the grinder adjuster.

Lift out the powder feed chute.

Unscrew the Torx T15 screw on the bean hopper.

Unscrew the last screw that holds the upper part at the front.

For most repairs, this is enough, you may also have to unscrew the back cover and remove it.
