Question about Coffee Makers & Espresso Machines
I have a Miele CVA 4085 coffee machine. Fault 73 showed up so I cleaned the brew unit, but it won't go back in. I think I need to realign it, but I can't get back to the main menu. I would be really grateful for any advice.

OK. Here's the deal. I struggled with this CVA 4070 (F 73) problem also recently, and even posted a questions in the cyber world about it. I jiggled, re-cleaned the machine, re-read the Miele manual, and scoured the internet for schematic drawings of this brewing unit's insides. No luck. Finally after finding out I'd have to pay $199 just for a service clown to walk in my front door, I said NYET!!! I must solve by myself. If I can take apart & fix my Dyson, etc, etc, I WILL DO THIS TOO!! (MUST HAVE COFFEE>>>)
Pull out the brewer, turn it a quarter-turn to your right, and look at the spot where that small black plastic piece -- shaped like a block "M" or block "W" -- should be situated. Pull it out, if it isn't out already. Don't worry about yanking it out or harming these parts, said the Miele troubleshooter guy in New Jersey on the phone. They're "made from the same plastic used in football helmets." Okey-dokey.
This approx. 1.5" wide, blocky plastic piece is part of the "slide" that takes the brewed coffee grounds into the waste container. When positioned correctly, it looks like a block "W," with the "wings" ointing up, and slides in just under a brown 1.5" flat piece. A small, down-facing tab on the brown piece clicks into the "W" piece and holds it in place. The "W" should feel fairly solid, although it is not rigidly in place, as the entire mechanism is a movable system to deposit the grounds in the waste receptacle.
Put everything back inside your CVA 4070 "love" machine, hit "on," and wait for it to go through its warm-up. No F73 message? Yeah! Mission Accomplished. You, like I, have fixed your Miele, saved your family relationships, and saved yourself a bundle from unnecessary service calls.

F73 is a bad brew unit. The cva 4070,4075,4060, and 4066 are designed to use espresso beans.
If you use an oily bean such as Starbuck's french roast, it will clog the filter in the top of the brew unit. If you catch it in time, you can just replace the brew unit. If you run the machine with a clogged filter long enough, you have to replace the brew unit and gearbox together.
Sometimes if you work with the tech support department, they will send you a brew unit to install yourself. If you live in an area that has Miele factory support, you may just want to get a service call. It is very important to rinse the brew unit every 24 hours, and to use the cleaning tablets in the trap door( not the descaling tablets) if not, the coffee oils build up and turn into a tar that will clog the brew unit. They run about 300 dollars so they are worth doing the maintenence on.

I understand the your Meile CVA4075 is showing you an F73 code. This code means that the brew unit needs to be cleaned. Here is a link to the owners manual on page 40 it shows you how to manually remove and clean the brew unit. The other issue you are having with the milk and coffe not being hot enough could be to the machine needing descaled.
