Hello Erno,

I found it! Mine is 470µF/35V. It's on the main board. Will do it asap. Tnx!!

 

[Erno]

I replaced the capacitor. Same problem. What else can be the problem? Everytime when the machine is off for a few hours it runs ok for one cup. Then it stops working after the full cycle (so, it does bring the coffee out and comes to resting position).
My mainboard is model -13.
I really like to repair my over 20 years old machine..

What happens exactly when you start the machine after the first cup? Did you try the test-mode?

 

[Erno]

This happens: I start the (cold) machine. All starts normal. Machine is heating (first led on, second led is blinking). After aprox. one minute the machine is ik (first and second led is on).

I now can take one cup of coffee. During this coffeemaking all goes well. At the end the brew section makes its cycle.

Sometimes not all the way, sometimes forward, back, and the not the third very short forward again). Then the red led starts blinking

When I put the machine off and then on again, after it just made a coffee, only the first led goed on and nothing happens…....When it is cold again (after a fes hours), the machine is ok again for one cup.

When the machine is not working and I put it in test modus: the pump is not working. Temp give furst and third led on.

Hello Erno,
did you replace the capacitor by a really new one?

If the red led starts blinking while operating the brewing unit there could be a problem with the limit switch (brewing unit insertet).
Try to move the brewing unit in the test-mode while the fault is present.
