Nespresso CitiZ Capacitors Replacement

소개

If the device no longer makes coffee, but the buttons only flash (irregularly), the capacitors may be dead. The replacement is not too complicated, the parts are very cheap and easily available. Use MKP capacitors, (X2 rated), 680 nF with 22 mm distance and 220 nF 15 mm distance, minimum 275V. You will need to use a soldering iron for this repair. If you never have soldered before, you will find useful hints here.

    • The bottom is secured by oval head screws.

    • These screws have an oval head that makes them look like rivets (picture 2). You need to use a special bit - also available at iFixit - for their removal. Here a DIY guide. If the right bit is not available, it could be done with a pair of needle nose pliers. Nespresso wants to keep us out of our own machines!!!

    • Remove five oval head screws securing the large bottom panel.

    • Note: this panel is smaller on models without milk frother.

    • The two colored side panels are only snapped into place. However, the latches sit very tight. You really need a lot of force. First lift the lower edge using a plastic opening tool.

    • Depending from the model it might help, when you first pry off the coffee spout. (See next step)

    • Unfold each of the side panels upwards and remove them.

    • The two blue capacitors must be replaced. The larger one is slightly glued to the motherboard.

    • Use a metal spudger to separate the larger one from the motherboard and fold it upwards.

    • The replacement capacitors have only very short connection wires. The 680 nF capacitor was therefore cut off so that it could be reconnected lying on its side.
