Step 10

The support of the upper piston is fixed with two screws on the left side. Depending on the model, these screws must be uncovered.
The first picture shows a model with an additional steam heater. Here the steam heater has to be unscrewed (one short screw on top, one further down), then it can be pulled out a few centimetres.
The second picture shows a model with a manual steam tap. Here the two screws on the tap must be loosened, then the steam tap can be pushed a little to the side.
Once the two screws are exposed, unscrew them.

Step 11

There are six connections on the upper brewing piston: three hot water pressure lines, one non-pressurized waste water line, a hose line to the coffee spout and two cables to the microswitch. All must be resolved first.
Pull out the clip at the top left and loosen the pressure line. Pay attention to the O-ring seal. It either hangs on the line or afterwards. When reassembling, replace it with a new one if possible.
Pull out the clamp in the middle and loosen the pressure line. Pay attention to the O-ring seal. It either hangs on the line or afterwards. When reassembling, replace it with a new one if possible.

Pull out the pressure hoses that are in the way through the openings on the left.
Detach any silicone hose that may be present.
The upper piston support plate is now free. However, it is very tight and it is tricky to get it out. Be patient and work carefully. Make sure that the ribbon cable to the control panel is not damaged.

Thanks for writing this up! The needed tools should be a security torx T20 (back cover), T15 (upper piston), Philips #2, and allen wrenches I think.

So I followed the guide but still no coffee or water from the coffee spouts. Water from the steam pipe still works. Any tips? New upper piston or something else?

VauWeh - Aug 5, 2022

Perhaps a broken or clogged solenoid valve?
