disruption

I have a fully automatic coffee maker
" Siemens Surpresso TK 68009 (S65) "When I turned it on today the display showed me
" Fault 2 " and a few seconds later " Fault 5 " an .
Can somebody tell me what kind of error it is and if I can fix it myself?

Hello,

these are fault messages which concern one of the heaters.
Which one now gives the message, I cannot tell you.
In any case, the affected person no longer heats.

Fault 2 indicates a problem at the thermosensor
and fault 5 means that the heater does not reach the intended
temperature.

Causes possible:
1. Heating loop defective
2. Overtemperature fuse defective
3. Thermal sensor defective
4. power electronics defective
5. control electronics defective

Most often several points occur at the same time.
Most often a mixture of 2nd, 3rd and 4th points.where
the basic problem is often caused by the power electronics
which is heated up unregulated due to a defect
until the overtemperature fuse burns out - in this case
the thermosensor often breaks down.

Hello BS

Many thanks for your answer.

As it is in your opinion one of these 5 possible causes, my question is ?

How can I as a layman check where the error comes from?

or must as a professional ran ?

I had disassembled and cleaned the machine before .

I know so about what it looks like in .

greeting Mowo

Hello Mowo,

In any case somebody has to get to it who can identify the electric (on)ic
fault (or a defective electric component)
so that you know which parts have to be replaced.

In general, you have to determine by measuring whether the
components are still in order. For 1, 2 and 3 there are
measurements:

1. Heater must have approx. 45-50 Ohm (and no earth fault)
2. Overtemperature fuse must have 0 Ohm
3. Temperature sensor has at 20°C approx. 12 kOhm

>for point 4 one needs advanced electronic
knowledge (I don't have either!)
and for 5. one has to be an electronic crack for electronics!

Hello BS

I am there again ( Betr. Störung 2 bzw. Störung 5 )

Yesterday I opened the coffee machine once, disconnected some cables from the power electronics and reconnected. Thought it might be the contact. At the same time I cleaned the brewing unit .

After the reassembly I tried the machine and it worked again ,until today noon .

The machine showed today in alternation ( malfunction 2 then / Heating device on .
That went about 3-4 times. The display then showed " large coffee ", as it was switched on on the machine and the machine worked again. Since the error will reappear in my opinion, (there must be a reason for the error message) you can perhaps tell me whether it is due to the power electronics ?

Hallo,

about this one should know more about the heating behaviour.

Try to find out if one of the 2 thermocouples
or has a loose contact, or an oxidized plug connection.

Of course there can be a
cold loosening point somewhere in the heating and control loop - or an incipient failure of a component.

Hello BS,

I removed and photographed the 4 cables once.

Cable 1: (fuse?) coffee heater.
The cable is plugged into the coffee heater and leads to the pump.

Cable 2: (fuse?) steam heater.
The cable is plugged into the steam heater and leads to the power electronics.

Cable 3: (thermal sensor?) steam heater.
This cable is screwed to the steam heater and leads to another cable.

Cable 4: (Thermosensor?) Coffee heater.
This cable is screwed to the coffee heater and leads to another cable.

PS: I confused the two cables 3+4 in the picture.
Cable: 3 comes from steam heater
Cable: 4 comes from coffee heater


Question: did I describe these 4 cables correctly?

Question: may the error be due to one of these 4 cables?
Question: how can I check these cables ?

PS: Forget the lower contribution !

Hello BS,

Sorry I have confused the above text to the picture somewhat .

>The correct order is .

Cable 1: (fuse?) Coffee heater.
The cable is plugged into the coffee heater and leads to the pump.

Cable 2: (fuse?) Steam heater.
The cable is plugged into the steam heater and leads to the power electronics.

Cable 3: (thermosensor?) Steam heater.
This cable is screwed to the coffee heater and leads to another cable.

Cable 4: (thermosensor?) Coffee heater.
This cable is screwed to the steam heater and leads to another cable.


>Had I described these 4 cables correctly?

>Could the fault be on one of these 4 cables?

Gruss Mowo

Hello,

Cables 1 and 2 must have easy passage. Then the fuses are o.k.

Cables 3 and 4 must have approx. 12 kOhm at 20°C. In case of wobbling
at the plug or the cable there must be no change (cable breakage)
Ebenso the plugs and sockets of the cables must give safe contact.

If everything fits, the fault will be on one of the electronic boards.

Plug contacts of the heating connections are not oxidized?

Hello BS
I had the cables checked through. All OK except :
The "thermos sensor cable" from the steam heater this one has 0 kOhm .So it will be because of that .
I'll have one sent to me to install it and hope it's due to this fault and the engine purrs again .

I will report back to you .

Many thanks for your effort You helped me a lot with your contributions .

Hallo,

0 kOhm are definitely not okay.
Then test it with a replacement sensor.

Hello BS

I ordered a "thermosensor cable bi " BND coffee studio " because the
error in my opinion is due to this cable.
-------------------------
As there is no sensor visible on this cable, I have to ask .

Sits the sensor on this cable in the cable lug, which is screwed to the steam heater
>br>greeting Mowo

Hallo

the sensor is where the thin cables go in.
the cable lug should be "bent" around the sensor.

Hello BS
Yesterday I got the " thermosensor cable " .

I installed it today and tried out the machine .

It works and I hope it won't let me down again so quickly .

greetings Mowo

Hello,

Then I hope with you on a
further problem-free operation
of the device.
