Jura Impressa S Model magnetic valve replacement

Introduction

The magnetic valve at the top rear can either be malfunctioning - in which case the water/steam draw will no longer work properly - or the valve body can be leaking. Replacing the magnetic valve is easy.

Note: This instruction also involves removing the top and side covers. However, this is only necessary if you want to do further repairs. You can just remove just the back cover if you are not doing any other repairs.

The backpanel is secured with two proprietary screws with oval head. They seem to be rivets, but in fact are screws. The only purpose is, to keep us out of our own devices. You can remove them using an oval drive bit. (Part of some IFixit tool collections or available at a Jura provider or iFixit). In a pitch try needle nose pliers. Here a DIY guide.
Remove the two oval head screws on the lower edge of the backpanel.
Lift the panel up.

The solenoid valve is located at the top left rear of the machine. (Marked in orange). It is installed in the sloping part of the cage for the heaters. The valve can be easily removed without pulling out the cage. If you do want to pull out the cage, you can find the instructions here.

Step 10

The white support of the valve is fixed in two slotted holes in the slanted part of the metal cage. The carrier must be shifted upwards by about 1 cm, then the valve can be lifted out.
The carrier is held in place by two small plastic catches. Press the plastic catches in from below with an angled pointed tool, then the catches are free.

Translate

Step 11

Lift the valve out upwards.
The valve is still connected to three cables. Pull off the cable lugs, note the position.
The valve is connected with hoses at the front and rear. Pull out the clamps and disconnect the hoses. An O-ring is attached to the hose for sealing. It gets stuck on the hose or in the valve. Replace it with a new one when reassembling.
There are valves that are equipped with Legris connections. Here there are no clamps, but the hoses must be pressed towards the valve, then the small ring on the connection must also be pressed towards the valve. Then the hose can be pulled out with a little force.
