Bosch VeroAroma 700 - no coffee

Hello all,

I hope that someone can help me.
We have a Bosch VeroAroma 700 with which we were very happy until recently.
A few weeks ago it started that the machine has repeatedly indicated that carbonic acid-free water should be refilled. Descaling and cleaning the machine we have done regularly.
Until a week ago, the error always went away after a few times off and on and
the machine ran again for a few days without problems
.

Oh yes, before the error message appeared, you could hear that the Punpe was working, but the whole thing always sounded very tortured, and no coffee came out.
Because it was already pretty worn and the coffee grounds were very wet, I replaced the brewing unit. The error message with the non-carbonated water nachfüllenist
but remained
.

After I with in the Internet some time by different contributions with similar error description by-read I have the motor-driven valve exchanged At first I was

very pleased, the brewing process runs through without error message, but now

all


the water


runs into


the drip tray (slightly colored) and does not come out as coffee where it should be


...



The coffee grounds are moist but not wet. During brewing, it steams slightly out the side of the brewing unit cover.
I put the old brewing unit back in, the result is that now
coffee comes out, but only about half the amount, the other amount of water ends up in the drip tray
.


Has anyone of you had similar experiences and can possibly help me with a tip on what it is ?

I/we would be very pleased about it !

Many greetingsThomas

A video with the front panel or side door open would be helpful here.

Hello,

I'll try to upload a little video once tonight.

Greetings and thanksThomas

Hello
,The video did not really work, I hope the pictures do it too.

In the meantime I have also pulled off all possible hoses and checked for continuity
.
All but one are continuous.

The red hose
leading
away from the flow meter to the back of the housing
seems to be closed.
Do you know if there is a valve behind it, or should the hose be passable when you blow into it
? Where does this hose go?

Unfortunately, I get the housing cover on the side of the brewing unit not down,
he hangs on the top absolutely firmly, I'm afraid that I what depart if da weiterdran
pull.....

Sorry, but I can't get any picture material here.

sorry, I had probably neglected to unlock the images as well, made up for it.
Would you please try again?

If I am correct you mean one of the red fabric covered hoses
leading to the pulsation damper
.
I mean a pure red rubber hose that
leads
from the
housing at the bottom to the flowmeter
.
This hose seems to be clogged.
At the flowmeter hang 2 hoses, a transparent one that comes from the water tank and the outgoing red rubber hose.

The transparent red hose leads to the low-pressure pulsation damper under the machine, to get to it the front and the base plate must be dismantled. The damper is available as a spare part. To dismantle the side, simply enter "Siemens EQ6 disassemble" on Youtube.
