Impressa Scala

Hello,

I have now revised the brewing group incl. drainage valve, replaced the transformer and the drive. Hurrah she runs again!!!

Since today only very little coffee comes into the cup. There is also hardly any water in the pomace container and the powder is dry.

I have set the setting to the largest amount of water.
Cleaning and descaling programs have also been run through.

Is this an operating error on my part?
Or does the machine have another error?

I am looking forward to an answer soon.

It wouldn't happen to be water coming out under the machine, would it?

No, the device is dry.

I have run through a few cups. Dry inside and out.
Not even half a cup of coffee arrives.

Is the pump any different from normal? Quieter? Otherwise I would just clean the flowmeter. That's the white part in front of the pump.

How thick is the "marc cake" with a normal purchase?

I'd say about 5-7mm.

mfg.

Then the grinding ring and cone are worn out. The machine "notices" that not enough powder arrives in the brewing chamber and reduces the amount of water drastically. For the counter test you can make a test reference with two measuring spoons powder coffee.

Right, with powder it works!

What can I do?
Repair set grinder?
Replace grinder?

Mfg.

Repair set for 30 Euro is enough!

Thank you, Hisholy. I didn't even think of the grinder. But you're right.

Hi Patrick,

I am also often on the wrong track

Gruß Stefan

so, now I've done it. I repaired the grinder.
This did not solve my problem. I can't even get half a cup of coffee full. The coffee tastes great and is also super hot. Just not enough in the cup. The case is dry and there is hardly any water in the drip pan.

Maybe one can help me.

How thick are the marc tabs now?

they are approx. 1cm thick and disintegrate immediately.

Mfg.

So too thin. Try a much coarser grinding degree.
