  8. The top cover is fastened with oval head screws. Unscrew them.
  9. 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. Jura wants to keep us out of our own machines!!!

  31. The motor for the drainage valve is located in the lower side of the unit near the center. It is fastened with three screws and connected with several flat plugs. In the picture, the ceramic valve has already been pushed off.
  32. Note: models from J6 onwards have a motor installed and not a magnet.

  34. Unscrew the three Torx T15 screws on the motor for the drain valve. Pay attention to the washers underneath.
  35. Carefully pull out the motor.

  41. The heat exchanger is connected with three hoses, and there is also an outlet in the base plate. When reassembling, make sure the gasket is still in place when you push the heat exchanger in. Make a note of which hose connects where.
  42. Disconnect the three hoses and lift the heat exchanger up and out.

  44. This exchanger was completely calcified and leaking because its cover plate was bent.
