@pglover19 Oven wall behind broiler element is definitely harder to clean, but that's also a deciding factor if you want broiler element in steam combi oven that can be used with steam at the same time, or if you can live without broiler element and have smooth oven walls with few interruption that are easier to clean. If I am not mistaken, wolf (as well as v-zug) steam combi oven also does not have top and bottom heating element. Anyway, if you get a Miele pyro oven that has moisture plus feature, you can always opt for doing spattering food in the pyro oven. I am from Australia, if you got confused with hvtech42's comment.

I don't know the answer but I am curious. if I were you (and having the benefit of hindsight) I wouldn't hesitate to call any of the Miele USA "Experience Centers" and ask to talk to any of the design staff. If you are in the US start with the Princeton, NJ center, their US headquarters. Even better if you can get to a center. The staff at these centers are a world apart from anyone you'll encounter at any appliance dealer, they use the products for demos and classes and typically have the appliances in their own homes. And it's their job to know the details on what you are asking. And report back and let us know. P.S: A little searching and I found this: https://www.mieleusa.com/media/ex/us/PressReleases/2021/9.2021_Generation_7000_Launch.pdf. Food View sounds interesting. There's also this thread: https://www.houzz.com/discussions/6229141/miele-7000-series-speed-combi-steam#n=10 Advice on calling the experience centers still stands.

First of, congratulations on your good deals for these three units. They will serve you well. For ventilation and wiring purpose, you will need a gap at the back of the shelf behind unit. For combi steam oven, this is where the oven sucks in the air in. It will vent warm air to the front underneath fascia. So following diagram #1 looks fine. For the sentence "The cabinet housing must not have a back panel fitted behind the installation niche", this must be from a newer manual of the combi steam oven. For example, see newer 6805 manual vs older 6805 manual. In a version that I have it uses "Make sure there is no back wall behind the building-in recess" which means that there should not be a cabinet back wall right at the cut out area. See picture for air intake in combi steam manual in installation section. In terms of installation each is 18" tall, just need to be arranged such that coffee machine is not too tall, and speed oven not too low. Perhaps somewhere where the bottom of the combi steam oven is a little bit below bench top level. A combi venting warm air at the front is not an issue for comfort. I have only combi steam oven in my kitchen and its bottom is at the bench top level which is very convenience, but that would put coffee machine a little too high up, if it is going to be on top. Here is an image from mile-vs-wolf-steam-oven thread. Found a funny image on the web of Miele ovens, noted the coffee machine location.

I have been researching various Miele combinations for the CSO and the CO both 24 inches wide. I had designed an alcove in the kitchen 90 degrees from the island for stackable CO and then the CSO XL. Both are the Sensotronic because the CO 24 inches doesn't come in the M touch. The CSO is unplumbed because I was told that filling the water and emptying the condensation tray is really easy. I am now re-thinking these choices. I thought getting the CSO XL was nice for daily cooking along with the induction cookop (Miele 30 inch or 36 inch, still deciding). But in looking at the XXL, it seems I could just get the XXL M touch and plumbed. Any thoughts: Is having the CSO XXL enough. I hear it takes an 18-turkey. The only reason to get the CO is perhaps for making a pizza, but the CSO XXL also has an intensive heat option. This is for a new home construction. All the Miele literature shows these gorgeous kitchens with all these stackable appliances. But having a single XXL at the right height as a wall unit also seems elegant, especially the M touch. All appliances are black and countertops are soapstone. 30 or 36-inch Miele induction with the downdraft extractor in the 7-foot long island 30-subzero refrigerator, with the 2-drawer freezer 36-inch Julien Smart Sink Thanks Suzanne.
