If a more serious problem in the fully automatic prevails such as a calcified valve or clogged Support flowmeter, then you should with Durgol sharper mixture take so: 2x Durgol on a tank capacity. Instead of the usual cycle of the engine should 1x cup of skim and rotating the Haan and wait 10-15 minutes, then skim off just one cup. This long do to 3/4 of the tanks are empty. After that the rest run through the coffee brewing in the brewing position and wait 30min and espresso cups skim up then the tank is empty permanently.

So Durgol comes on to where normally never get there a descaling agent, namely the valve support what is behind the brewing unit.
By brewing the wires from getting even durgol, block them also like once. Then, of course, clean the brewing unit thoroughly.
When Support valve and brew group (the Seals) with a little silicone grease (smidgen) brush.

Durgol creates here really the 3x aforementioned problem areas to correct any fully automatic.
However, you should always make it so when the flow meter is completely full gedreckt times, only one expansion helps nor its :)
Is the problem Allerding very bad, (comes little coffee into the cup and so on) 2x Durgol into the tank, then let 1x cup by steam and by the coffee dispensing run and then leave for the night and the next day to continue only as above described.
