EAM3500, no hot water

EDIT:

>done



Moin community,

so , there we have a pretty clear error description...
- no water
- no steam
- pump runs quieter than normal

That looks so hard after a lime plug.

However I have a wandering error....

First the solenoid valve was tight, then the flow heater and now - no idea -
then stopped searching.

The only thing that doesn't fit correctly into my error image is that the print isn't
reduced.
Do I see correctly that both the valve on the pump and the solenoid valve release the pressure?

My current idea is to take everything apart and test it for passage, put it in
Decalcifier and reassemble it.

Do you have any other, better suggestions?
Or do I overlook anything?? img src='/forums/html/emoticons/ohmy.gif' style='vertical-align:middle' alt='ohmy.gif' />

Do you see correctly, but also at the thermoblock there is an overpressure hose, namely the black one, which goes out laterally.

Your current idea is correct. But be careful with electrical components such as the thermoblock, there have been people who have inserted the complete TB and later wondered why the FJ falls when they switch on the engine.

>Do you also know that you have to decalcify the upper brewing flask separately with DL?

Moin Stefan!

Had been waiting for your answer... , your current idea is right. But beware with electrical components such as the thermoblock, there have been people who have inserted the complete TB
> and have later wondered why the FJ falls when they turn on the engine.

I'm practically from the trade, more electronic heavy, but that fits.

>>Do you also know that you have to decalcify the upper brewing flask separately with DL?

Nö, but I've suspected this for quite some time.
Can there be reactions?
The brewing flask is "only" in the way between the thermoblock and the front solenoid valve.
Axo, I didn't mention at all: espresso is still possible. Then points to
the part "after" the thermoblock.

Do you still have a hint how to get the acid out of the case.
If there's still pressure on the lines, that's pretty good.

greeting pit

Oh, now they're waiting for my answer!

What case do you mean? TB or steam heating or something else?
You're right with the upper brewing flask, I just wanted to mention that it has to be decalcified separately (via the flushing function or also the cleaning program).

The complete outer housing!

What do you think it looks like in there when you pull off a pressure hose,
with acid inside....

Hopefully your "acid" is not citric acid or vinegar.
Only use amidosulfonic acid (e.g. Durgol), because citric acid only dissolves lime and not lime. Then there's plenty more plugs.

If I were you, I'd go through tube by tube, component by component to find the clog.

It's already clear! I know the prob!

That you know the exact reason:

Really good the Prof!

I.ü. would decalcify acetic acid well, but is too aggressive for gaskets, etc.


>Is all apart and cleaned and since last night in acid.
Other plugs are found in the valve.
MMMn, the deposits of "before the pump".
The silicone tubes there have incomprehensible way deposits?!

Same I know more!

Update:

So, water flow free again. The valve for the steam was blocked again.

Allerdinx the brewing piston is now tight. I could ko****

Well, it's my own fault. I never decalcified it.
Why didn't DeLonghi say that in the manual??

Now it's tabula rasa, I order the XXXXL-set from the Juraprofi.

Nor a question about the solenoid valve. Unfortunately, I did not pay attention to the installation direction
. Does anyone know how around it is connected?

I've asked myself that before, but only Delonghi knows that.

I don't know the installation direction by heart, but Gregor once wrote "So the arrow on the valve must point in the direction of the thick silicone hose."

What??

The silicone hose is going up?
The flow direction is from "right to left".

Achso, I haven't found an arrow yet, there is only 1, or 2, so probably
In and output.

Parts are ordered anyway.

I also think that is 1 entrance and 2 exits. There seem to be different ways of making the valves.

So what's new:

machine apart and all O-rings changed.

Now I have a new problem, hot water is running, pump sounds good.
ABER, rinse and brew doesn't work. The rinsing water is pressed out via the overflow of the
brewing piston unit.

I strongly suspect that I have swapped the high-pressure lines on the thermoblock.
Can someone confirm this, or what else is wrong?

How are the lines laid correctly?
On the Juraprofi instructions only the heating parts are visible...

My installation at the moment is:

From the pump to the upper record of the thermoblock.
From the lower chord of the thermoblock to the solenoid valve1.
From the solenoid valve1 to the steam generator and from there to the solenoid valve2.

Oh, I could choke!




Axo, the overflow of the brewing flask was completely clogged with pomace, this indicates that something was not OK there before.

Hello Pit, I am unfortunately only at the WE back home, by heart I can't tell you now unfortunately.

Hi Stefan,

>the piping seems to be right, I already found a picture in the net.

>Do you have an idea what could be "blocked" if the water doesn't go through the
brewing head and the brewing group??
The soup simply runs out of the overflow of the thermoblock, the brewing head stays dry....

Hy Pit, since hot water goes, one can limit the troubleshooting to the BG and the upper brewing flask. You probably also changed the seals in the upper BK, maybe something went wrong. On komtra.de you will find a good manual for the upper BK, have a look at it.
