Jura Impressa Model S Noise suppression filter replacement

はじめに

In the meantime, the Jura S models are getting on in years, and some parts have aged considerably. The interference suppression filters can break, often already recognizable from the outside (or from the smell). Possibly the machine triggers the fuses or can no longer be switched on at all. Pay close attention to the correct spare part, depending on the model, the filter has different connections. The exchange is quite simple and is shown here on the model S70.

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.

手順3

The filter is fixed in the black carrier plate by a dovetail joint. To remove the noise filter, you have to push it about one centimeter to the right. It is held in place by catches, which you have to push away.
Carefully lift the filter out of the carrier plate.
The picture shows the old filter at the top and the replacement part at the bottom. The new version looks a little different, but fits. On both versions you can see the dovetail guide that holds it in place.
Disconnect all connections of the filter and remove them from the machine.
