Jura Capresso IMPRESSA J5 Replacing the heat exchanger

Giriş

If water is dripping under the floor panel in the front right area, you need to investigate where it is coming from. Check the water heaters, ceramic valve, exhaust valve and their hoses. If everything is dry, the somewhat inconspicuous heat exchanger could also be leaking at the bottom. It is made of light metal, its lid has only one screw in the middle. The lid can warp and is difficult to seal. A new heat exchanger solves the problem. To get better access, the ceramic valve must first be loosened, its connections can remain. The outlet valve should also be removed, the connections can remain.
