from my Barista F73 /1-101 comes neither rinse water nor coffee, it all runs into the drip tray. At the brew group I have replaced all seals and the small hose, cleaned the brewing sieve. and the drainage valve is also replaced. All without success.
When I look into the machine from the drip tray, diagonally upwards on the brew group, I can see that there is hot water spraying under pressure.
Where is the fault? What is defective?
When I blow into the water supply hose to the coffee strainer, air comes out of the hole (red circle). Is this correct? Can the water come from here? What is defective there?
my measures: Changed all the sealing rings of the brew group, including the small hose. The Cremaveniti gefrüft and made clean. The drainage valve replaced, dan hose to the outlet replaced. Now I have ordered the inlet angle new, although I do not believe that it is because.
I am at a loss, what should I still examine, check? Who can give me another tip?
The rubber at the top can not be installed incorrectly as far as I remember. Unless the upper piston is not pushed up far enough to close the hole. Do you know someone who has the same brewing unit to test whether it is then gone?
