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.

  • 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.

Ansonsten - Gute Anleitung, hab wieder eine funktionierende Kaffeemaschine.

Danke dafür!
