Miele coffee maker cva 4070
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.
