Introduction

These instructions show you how to disassemble or open the coffee machine. The housing parts are not easy to remove—it takes a little patience to find the right places to unclip them with a screwdriver.

Step 1 Open the housing (top)

Flip up the water tank cover and unclip it.
First lift the top cover at the back, as shown in the photo. The screwdriver can be inserted at the yellow markings.
Then slide the cover backwards. When open, the hooks are clearly visible. You can also see the side wall fastenings from the inside. Use a flashlight to illuminate the interior to better understand the side wall fastenings.

Temperature safety switch (reversible) and temperature fuse as a double component.
Ribbon cable to the coffee capsule scanner.
Sensor connectors (water level, temperature top, temperature bottom, ???)
Capsule replacement plate for cleaning process. The barcode is read out in the brew element. Without a capsule or the plate the machine will not operate.
Cut the cable ties and remove the hose. Insert a toothpick into the outlet of the pump from below – this will release the check ball. This was stuck or blocked by limescale and prevented the water from flowing.
If you want to check whether the heating element is so calcified that water can no longer flow through it, this hose must also be opened – as must the hose on the other side of the heating element.
