I think it's best to call Miele. There are two sensors in the dryer: 1) one on the three long paddles inside the drum to read fabric moisture and, 2) one inside the exhaust plenum to monitor heat and to shutdown the unit if the exhaust gets too hot, thereby notifying you with the panel light. Either the exhaust sensor is bad, or there is something obstructing the exhaust in the machine itself. Someone earlier mentioned that they found a part, located within their 9800's exhaust, out-of-skew when they checked their unit. However, I would not mess with it, and while the Miele Tech rep is there (insist that a factory Miele tech rep. comes as they have the software, and hardware to properly work on your units) ask them to also upgrade the firmware on both your washer and dryer, if needed.

If you pull the service manuals for the Octoplus machines they are different. The outside basic shell is the same, but what went inside was different. The professional machines have full stainless inner and outer drums. Stainless vs Aluminum spider. The shocks are much beefier. The drum is horizonal and not inclined. There is no captive rubber boot for the door. The last one is why Miele won't sell the octoplus to residential customers. It is possible to get little fingers caught between the door and frame. The upside is that without a boot there are lot fewer problems with water being retained in a boot and you get a better seal. They are setup for external chemical dispensing. Designed to last 30k instead of 10k hours. Etc. Etc. Miele made too many compromises with the 27" residential units. It backfired on them. Now they only offer their worldwide residential 24" and professional 24" and up sizes. There was never a gas version of the octoplus dryer that I was aware of. It was electric only. The electric versions of the T98xx dryer had fewer problems. Most of which were related to the machine being overloaded. The octoplus is rated to hold a full drum worth of clothes. The residential models were not. It was very easy to put 1.5 to two times the amount of clothes in the residential drum vs what they were rated to hold. For marketing and customer education that is really up to the reseller. Some dealers are really good and others just sell you the appliance and you are on your own. Miele's manuals are fantastic. Much better than almost every other manufacturer. Many people do not read the manual cover to cover so they are unaware of all of the available options and any required ongoing maintenance. We are a family of 13 people now and we have ONE set of W1/T1 laundry. We do ALL of our laundry in them. From towels to dress shirts, wool pants and sweaters, sanitize when needed. Never had one problem with them. I did replace the foam filter on the dryer which is in front of the condenser after 3000 hours as it was starting to wear out. (This was mentioned in the manual) I think looking at the size of the new washer/dryer gives a lot of people pause. It is NOT an issue if you are accustomed to doing laundry every day. With the size of our family it is 4-6 loads per day. We can put 12-14 Costco size bath towels in one load for perspective. You can fill the drum all the way up as long as you don't pack it tight and lean on the door to get it closed everything will come out clean. It's too bad you didn't have better luck with your current appliances. I can see how that would taint your view of Miele.

Molly is talking lack of controls because she is comparing the new Miele's with the older ones. The older ones let you program in extra rinses, high water...this and that and you did so right on the console. I believe mine is newer than Molly's but it still has the selector dial, but some of that programming was removed, although I can still get the machine to do much of it. The older ones like mine had different cycle selections in that you picked a fabric type such as cotton, silk, wool, perm press.. and then within each fabric type you selected a temperature from tap cold up to almost 200F in some cycles. The newer ones have the push buttons, with names like Sanitize..whatever.. but I am used to thinking"this is cotton and it is dirty and there is no elastic in it,and it is color fast so I am washing it at 180F" But the 4840 does have the custom cycle which will let you customize the cycles. So I think the new Miele models are going to offer as much if not more control than many of the current models sold today...Just not as much as the ones before. My neighbors see the options on my machine and their eyes glaze over and they say "I just want to push a button and go, I don't want all of this" so for the most part the current overall market didn't want what was Miele was offering.... Folks like me are used to those selections and flexibilities so I will be keeping my "OLD" miele washer for as long as I can. I have the new gas dryer and it is fine.

Fahrenheit, any idea where that service man could be found? Everything I'm finding leads me to "user" manual...i have the sides off ...I did find a small screw that looks like it stabilizes the motor is missing...so I'm guessing that put a lot of strain on the belt allowing the belt to move around too much...I'm guessing I just need to remove the screws that hold drum in and try and slip belt in...darn high end machines...haha
