Hello everyone,
I have had a Melitta Caffeo CI E970 for about 5 years. So far, I have brought it to about 6500 covers.
2 years ago, I replaced the drainage valve and the seals of the brewing unit, because the machine no longer wanted to dispense coffee. After that, it ran perfectly until recently. Regular descaling and cleaning are carried out.
For 5 days it has been continuously releasing less coffee. In the beginning only 120ml were distributed with 180ml selected, now it is even less.
A renewed exchange of the drainage valve and the seals of the brewing unit unfortunately did not lead to success. On the contrary. I feel like the coffee's gotten even thinner now. Immediately after the brewing process, half of the coffee is placed in the drip tray and the marc container. There is also a part in the brewing unit. If you take them out after making the coffee and turn them over, the coffee will run out. The flushing also no longer works as usual. A larger amount of coffee powder remains on the sieve of the brewing unit.
Always when the ground coffee beans are compacted, I imagine I hear a kind of hissing sound when water escapes under pressure.
Do you still have ideas or tips for me?
Many thanks in advance!
