Miele CVA 4085 Fault 17

SOURCE: leaks at the hot water spout during coffee brew

I had the same problem. I ended up taking the coffee machine apart and found that the reason coffee trickles out around the hot water spout is that the two coffee nozzles were partially plugged. Since I Had parts of the coffee machine apart I was able to clean it easily. It may also be possible to clean the assembly using a pick of some sort and clean out the holes of the two normal coffee spouts. Inside it is just a open cavity so gentle poking around and using some steaming hot water may do the trick.
If you want to take the machine apart you need to do the following: 1) take of the warmer plate on the top - 2 storz screws but an allen key works as well 2) take off the top plate of the machine - another 4 or 5 screws - make sure you empty the beans first otherwise you will have a mess 3) remove one screw from the right hand side of the removable coffee ground tray. Once this screw is removed the front panel is free to swing open except for the pipes connecting the front 4) unclip the steam assembly - there are a couple of plastic catches on the top. this will free the steam assembly from the front panel and also free a pipe connections. The steam dispenser pipe will also come free from the steam assembly. 5) remove the coffee pipes from the up and down sliding coffee dispenser. This is a small whitish color clip with 2 pipes connecting into it. The white clip has a little plastic catch on the top that frees it. The front panel should now swing open freely. 6) remove the sliding coffee dispenser from the front door. There are 4 plastic catches, 2 on either side. the whole front sliding coffee displenser now comes free 7) Take the sliding dispenser apart by release the 4 plastic catches on the front curved planel. 8) Inside the sliding dispenser is a white plastic piece that connected to the piping released in step 5. There is a small plastic catch that needs to be pressed while pulling fairly hard on the plastic piece and bending the whole piece. 9) You will now see the plugged spouts. It goes back together really easily.

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.

This is most likely due to a bad o'ring. The bar you speak of...Does the unit have a small spout pointing upward from the area?...with a groove? Is the o'ring in that groove damaged or missing? When the grounds are compressed in the piston, the brew unit lowers down onto this spout and seals on it. The high pressure water then is injected upward inot the brew unit. When this seal fails the water simply leaks into the tray when there are grounds providing backpressure. When rinsing and no backpressure some of the water may be getting through. Make sure you lube up any seals with a food grade lube. Olive oil will work in a pinch.

I just switched machine off for a few hours and when started, it was OK

The Multivalve seems to be stuck. When you start up the machine you should hear the multivalve turning 2 times, if it`s silent, the valve is defective. This valve is important to guide the water in the right direction. Contact your servicedealer and let them have a look. There`s also a small chance that the electronic board are sending wrong or no signals to the valve
