Miele CVA615 In Wall Coffee System Review

Update 9/13/2018:  About 18,000 cups brewed and the machine stopped pushing water out.  It was making a sputtering sound and lots of steam.  I did the typical descale and cleaning cycles but it didn’t help.  Using the service manual, I did the pressure test and it showed there wasn’t any pressure.  I ordered an Ulka Model E Type EX5 water pump on Amazon for $35 dollars and that fixed the problem.  To replace the water pump, you have to take out the coffee machine, remove the top cover and then you should see the water pump.  Remove the blue and white wires and note which one goes where.  The water pump is secured with two rubber mounts which you can only be removed from a screw at the bottom (impossible to get to).  The way I removed it is popped off the hose on the side closest to the water tank.  I then was able to slip it through the rubber grommet which only left the other side to be freed.  The side with the brass shaft can be unscrewed by holding the solenoid and gently turning the pump.  Once freed, you can replace in the reverse order.  One other issue I had was the hot water stopped working.  I removed the front cover and somehow the brown wire broke in half!  I think all the open/closing of the door caused it to wear.  Simple solder/patch fixed that issue too.

Update 1/3/2016:  One issue I have been having is that behind the brew unit, there is a little cavity that constantly would fill up with coffee sludge.  This is basically where the inside of the coffee machine meets the brew unit.   To clean,  I would get a paper towel and wipe out the water and coffee grinds.  What I didn’t realize until now is that it’s actually suppose to drain down below and ultimately into the drip tray.  Simply get a pipe cleaner or something bendable and at the far left (you can see it), poke around until the water flows freely.  I used a turkey baster to shoot water in which also helped remove the blockage.  Miele doesn’t say to clean this in the maintenance schedule, but I would recommend doing it every time the unit needs a descale.

Update 12/25/2016:  Just a quick update.  13k cups brewed and going strong!  If you are in need of parts, the Saeco Vienna Plus shares the same parts as this Miele CVA615.  Here is a detailed parts diagram and an online place to buy parts.  Additional part diagrams.  Just be careful and try to match it up with the original Miele part.

Update 11/19/2014:  We are over 10,000 brewed cups and some “brewunit block” issues have been coming up.  Before you panic, do the descaling and rinsing maintenance and then thoroughly clean and lubricate the brew unit.  I believe a sign the brew unit needs maintenance is when it does the System Test and you can hear the motor strain.  I’m still having issues with water leaking behind the brew unit (ultimately into the drip pan) I might buy a new boiler valve and replace it.  The Miele parts are shared with the Saeco Vienna which you can find online.

Update 5/7/2011: After about 4000 brewed cups we started noticing that the well behind the brew unit was filling up with water [which is normal], but there were grinds everywhere. To fix it, you should make sure you run the descale process and the rising cycle. The rising cycle is key in removing any oils that have built up in the brew unit. Additionally, replace the boiler valve o-rings per your owners manual. I had to replace the brew unit o-ring [called #4] as well. I ordered it from Miele for about 15 bucks and it’s part number: 5049900 I also found the service manual online so posting it here as well: Miele Service Manual [6mb]

I just noticed the Miele CVA 4075 model features a plumbed-in water connection. Don’t you hate it when they improve products after you purchase them?

Our system is still working great and we have had zero problems. We’re up to 518 cups. The only issue I have had is that someone, who shall rename nameless, was not emptying the grinds when the water was refilled and there was a slight overflow problem.


We recently redesigned our kitchen and we thought a coffee center would be a cool addition. There really isn’t a lot of choices in wall mount units so it was either the Miele system that used coffee beans or pods. I didn’t like the idea of pods since they are more expensive and would have to be special ordered. The CVA 615 system I decided on uses regular coffee beans that you can find anywhere.

We had our Miele installed in the middle of the wall by our pantry. We also had a custom draw built to go under the unit to hold coffee cups, tea bags, sugar, etc. The idea was a coffee station.

To be honest, I’m not a coffee aficionado. I probably couldn’t taste the difference between a hot cup of fresh coffee from 7-11 vs. Starbucks. Ironically, I mainly like to drink tea that I steep myself. A lot of the tea I use recommends steeping at 212 degrees F. From doing a test, it looks like the max temperature the hot water is about 160 degrees F.

Hot water temp reading

The water definitely comes out hot, but not boiling. I made tea quite a few times and really didn’t notice the lower temperature so it works fine for me. If I had to, I guess I could microwave it for another 30 seconds, but that kind of defeats the purpose. Unfortunately, there doesn’t seem to be a way to adjust how hot the water comes out.

For coffee, there are a few temperature adjustments. To be specific, there are 5. At the “medium” setting, the coffee comes out at around 175 degrees F. I couldn’t imagine any hotter than that, but coffee gurus would know more than I as temperature affects the crema.

Coffee temp reading

As you can see, the coffee comes up with a nice froth and crema on top. I think it tastes great and that seems to be the consensus of everyone else that has tried it. Of course, once you see it working, it’s hard to believe the coffee wouldn’t taste great. I’m really happy with the unit so far and hope it gives me many years of trouble free coffee.

I don’t know of any other reviews of this unit on the web so if you have specific questions, leave a comment and Ill try to answer.

    Hi,
    I recently descaled and cleaned my miele, and it just STARTED having coffee grounds all over the inside. Any tips?

    Also, after the clean and descale, we cleaned the brew unit thoroughly and lubed it. Within a week, we had the dreaded brew unit jam. Am I overlooking something obvious?

    Thanks

    I haven’t had any brew unit jams, but I do still have issue with the coffee grinds being very wet and causing a mess. It seems replacing the o-rings hasn’t helped much and we should have to be more diligent on cleaning it. I wish I knew the issue though…

    Hey! Thanks for this post. I also have a CVA615, and I’m trying to find replacement o-rings. Any tips for where to look? I specifically need the two “water valve” o-rings, found behind the brew unit.

    Can’t seem to find part numbers or replacement parts very easily. 🙁

    I have a miele coffee system, CVA615. I dropped the water tank and cracked it. Is there somewhere that I can order a new one?

    Help! Need a parts diagram:

    I have a CVA615. I can’t seem to find anywhere online a Schematics manual. I need a detailed parts list and/or diagram for both the machine and the brew unit.
    Last time I inserted the brew unit I found a spring had come out of somewhere, thus the need for parts diagram. Brew Unit won’t give me that nice click-in sound when inserted. What is really strange; it will work fine and brew coffee but comes up with the “Brew Unit Missing” warning as it is brewing?

    Thanjs for the 13k update. Just got past 14k on my own cva615. What settings do you have your coarseness and quantity set to? I have the coarseness set to minimum for fine ground and the amount of grinds set to max for strongest taste.

    I saw you mentioned you had a leak, I had the same issue with a lot of water filling my drop tray, ended up needing to replace the pressure/boiler valve (11 or 14 bar, can’t remember). It’s was a tiny piece and fixed everything, no more leaks, barely any water in drip tray now.

      I have basically the same settings for grounds/amount that you have as well. Regarding the leak that you fixed, in the service manual (section 4.20.1) says “The Pump takes in water from the water tank. (The Pump is fitted with a safety valve which opens at approx. 16 bar (232 psi) system pressure. If the pressure is too high and the safety valve opens, water is drained off via a hose to the drip tray).”

      I think that is what you might be referencing, but I can’t figure out which part it is. Do you mind looking at the service repair manual (I have the pdf linked to in this article) and let me know which part it is? If I can fix this leaking issue, I would be thrilled! Thanks.

        Hi Frank,
        I just acquired a CVA615….it works fine on the first cup or two of coffee; then it does what you describe where I get weak stream of coffee dispensed, maybe an ounce, and the rest of the water makes it way into the drip tray. I end up with basically no coffee in the cup!

        Your note above about a pressure value is interesting… in 4.20.1 is says the “Pump is fitted with a saftey valve”… and 1.3 would indicate therefore that the pump is #19 and in the center of the unit, and the safety valve is attached to it somewhere.

        Anyways, let me know what you think….be great to solve this.
        Then I can move on to why I cannot get coffee above 150 deg!

        Thanks

    Excellent posts re the same machine I have!
    I do have a question though if anyone has any guidance.
    A month ago my water tank had drained into the drip tray and indicated a water system fault. I emptied out the drip tray and the fault cleared and it seemed to work fine again. A week or so later it did the same thing. Same actions and worked again for a few weeks. It then did it again, so it seems like an intermittent leakage somewhere. I read about the safety valve setting above, but being an intermittent problem this would seem unlikely to be the issue? Could it be the rubber lip seal where the water tank fits into?
    Any suggestions or similar experiences appreciated.

    I know this thread covers a long period of time, but as TJ said in 2013, I also am finding ground coffee (dry) all over the inside. I do the usual cleaning maintenance recommended. What am I missing?

    Thanks for letting the public know about the Saeco Vienna Plus shares the same parts as the Miele CVA615. You saved me a lot of money on a brew unit (I did need to swap outlets).

    Appreciate your help!

    hi Frank
    great posts, thank you.
    Our system, a cva 4075 installed in 2007, started to be erratic, sometimes coffee sometimes water. We put up with it for a long while. Then water started to appear in the waste bin and
    not long after that, it stopped making coffee. Grind motor was spinning but not making grinding sound and only water came out. Switched to using ground coffee, while i figured out my options. No water in waste almost dry.
    Decided to take unit apart and found grind chute packed with caked up coffee, grinder looked in good shape. its all clean now and i am looking for another 10 years of use . The only fly in the ointment…..i can’t remember where the red wire and white wire connect to. I took pictures of everything except that step. Miele will not supply a wiring diagram to the consumer. Do you have any idea of where i could get one. Or if you can clue me in, i would really appreciate it. Different model, but same motor so if not exact connections, it might steer me in right direction. I have been staring at it for three days trying in vain, Tried to get something out of the interned but no luck except your site, thanks again. None of the manuals available to me have a wiring diagram or schematic,
