Saeco Tealea Ring Plus - no coffee output

Hello together,

I have the following problem with my Saeco Talea Ring Plus.

The first thing the machine did was to build up the pressure but not brew any coffee and release all the water into the container. I replaced the valve connection because I thought it was defective/clogged.

Then it didn't work and it made strange noises. Within the brewing group I noticed that plastic parts were broken. This was then replaced. However, the brewing group is often not recognized correctly or does not engage properly.

Now the machine builds up pressure again and lets all the water back into the collecting tank. It doesn't flush either. Ground coffee falls relatively wet into the collection container. The collected water is nevertheless clear. The coffee is not distributed. The steam valve works.

I hope someone can help me so I can enjoy coffee again.

Drive disengaged...? Brewing unit still defective...?

Heavy to say without seeing the device...

drive, I wouldn't know where from.
Brew group was completely replaced, so I'd want to exclude them.

Something could have slipped or broken on the engine. I just need to check it out.

I'd be happy to have a look if you could explain how to get this. I am not the vending machine expert now ;-)

...Mmh.. certain knowledge should already be there...otherwise you should not screw yourself...
