Einleitung

If your machine suddenly turns off while heating up or brewing, one or more bad capacitors are often the cause.

  1. Remove the plastic water tank
    • Remove the plastic water tank

    • Remove the iron sheet and the underlaying black spillover pan

  2. Turn the machine upsidedown and lose the T10 screw right next to the power cord Lose the four clips on the side. Use a spudger or a flathead screwdriver to gently bend the little plastic clip on the outer side of the rectangular hole inwards. Use your other hand and a spudger or a plastic card to lever off the coverage. Do this with all four holes.

  3. Disconnect all cords from the circuit board besides the two black ones on the right(marked black on the first picture); these are soldered and therefore cannot be disconnected so easily.

    • Sometimes the two smaller capacitors (0.047 microf) are also damaged. Test the machine after step four, if it doesn't properly work, replace these two as well.

Die zwei kleineren Kondensatoren haben 0,047µF, nicht 0,47µF.

Ansonsten - Gute Anleitung, hab wieder eine funktionierende Kaffeemaschine.

Danke dafür!

Hallo, ich habe sowas noch nie gemacht (Hausfrau im fortgeschrittenen Alter :-) möchte aber meine Petra retten. Lötkolben ist bestellt, die Maschine ist geöffnet aber jetzt scheitere ich daran, dass ich nicht weiß, wie ich die Kabel abmachen soll! Gibt es da eine Trick? Die sitzen ziemlich fest und ich möchte nichts kaputt machen.

Ich (58 Jahre und noch nie vorher gelötet) habe es nach Deiner Anleitung geschafft.

Dankeschön!
