Miele CVA 4070 Cappuccino Maker

I got this machine from a friend of mine for doing some electrical work for him. It was not working, but after tearing it down, re-greasing the brew unit gearbox (and all of the O-Rings since I was inside the unit), I was able to bring it back to life! Though it's an older model, like 12 or 13 years old at the time of posting, it's still a well built sweet machine! Makes great coffee and cappuccinos!
In this video I pre-froth the milk, then make a cappuccino, this process grinds the beans and brews the cappuccino (it also froths the milk, but I like a lot which is why I pre-frothed a bunch, I'm actually making a white chocolate frothy mocha). I then rinse the frother, then rinse the unit at power off.
*Sorry for me rocking back and forth in the background, that's my ADHD shining through.

The percolator gearbox is what I had to remove and grease. It had coffee grounds in it and the old grease was hardening up. Made a grinding noise when I tried to use it. Been working great since. It is a pain to get to and grease. Because it has a specific position (timing mark) you have to get it in when you put it back together. It wasn’t fun lol.
