No more hot water and coffee

Hello,
I have de-iced my Delonghi ESAM5400, and most of the water has already been pressed into the collecting tray. Through the hot water
nozzle almost no water can be used.

Same

with the second try.

Now you can only brew one cup of coffee at most and then

again no water comes.

I have tested the error description several times,

unfortunately without success.
What can
be
the
problem?

The pump or something

else?
Greeting Detlef

Try to start the rinse program repeatedly with descaling solution in the water tank.
I would wait about 5 minutes between each rinse. When the descaling solution has completely run through, rinse with clear water
.

If this does not help, all that remains is to dismantle the brewing head and brewing group. Then decalcify manually.
