there is a long thread on her ethat you can look at i do have one and like it. To answer your questions the washer drum isze is ok for us - you can put alot in there. The dryer cannot be overloaded or the clothes will wrinkle. Also, the clothes will feel slightly "damp" when first pulled out. In a minute or two in the air the mysteriously dry. You should tak ethem out when they are done to minimize wrinkles the heat pump really doesnt add an heat to the room drying times are reasonable. i dont think they are actually any longer than others dryers - maybe a few minutes i am 6'6" and dont mind the reach into the drum

Just to share. Since I purchased a Miele W1 I could no longer use the King size comforter I was using. This is what I purchased at it washes very well on Normal cycle in my W1. There is some room to give in drum. I would advise to only use water plus without max rinse level. Maybe a touch of fabric softener. https://www.wayfair.com/bed-bath/pdp/nautica-adleson-single-reversible-quilt-nal1680.html?piid=15425096

I got my w1/t1 set in January to replace an old top-loader. I didn't get the TwinDos version. Our clothes have never been cleaner. The whites are whiter, stains I thought were permanent have faded or disappeared. I'm very happy with these machines. Since the coronavirus outbreak in my hotspot city, I've been selecting the "pre-wash" and "extra rinse" options on every load, pushing the cycle time up to 2.5 hrs. The heat pump dryer is excellent - I adjusted it to our soft water and it dries clothes quickly. A load of towels and bathmats dry in under an hour.

@silveretta Zone 6a MA You can safely ignore the TwinDOS reminder to use it or run a maintenance cycle. It really only matters if the system has not been used for a long time, like months. Push the OK button when the warning comes on the screen and it will be dismissed. Enable the option to remember the last used settings. It is called "Memory" under settings. Then if you turn TwinDOS off it will remember that on subsequent cycles. You will have to remember to turn it back on if you want to use it. I have that option enabled and when others use the washer they sometimes forget to turn it on if it was off. It is possible to turn twinDos off all together in the service menu, but that really should not be needed. For the water intake fault there are usually two reasons for this. One is there is crud stuck in the little screen filter in the water supply hose. There is a little screen in each end of the water supply hose. Designed to catch big pieces of crud before they enter the washer. Crud can slow the water flow and cause the intake fault warning. The other cause is low water pressure. If you have low water pressure and the tub does not fill quickly enough that can trip the intake fault as well. There is an option under settings called low water pressure. If you enable that the machine will allow for a longer fill time. While it is possible to have a faulty part, it would be very unlikely on a newish machine. To test and see if the suds are from your clothes go buy a BRAND NEW towel from the store. You need one anyway right? Turn off TwinDOS and use no detergent. Run the towel on rinse and spin cycle (under more programs). Observe if there are any suds. If there are no suds then you have confirmed there is detergent build up in your other clothes. If there are minor suds then these can be caused by simple air bubbles in the water. Make a note of how many there are and that is your normal "Clean" water. Another way to test is to fill a cup or glass jar half full of water, seal it and then shake it up for 30 seconds or minute. Note how many suds, if any, are produced. This will give you an idea of how many suds are generated in your "normal" clean water. Once you have a known clean towel you can run a few cycles. Bump the Dose for agent 1 up in 5ML increments. You will know when you have reached the correct amount for your water when the water rinses clean, but you have suds during the main wash. You can always go a little over and then back off when you notice more than your "normal" amount of suds in the last rinse. Citric acid would be un-needed if you have really soft water. Its main use is to remove built up mineral scale from the outer drum, heating element and any parts and hoses wash liquor is circulated through. If you have really soft water or a water softener then there is no mineral scale to build up. Even in REALLY hard water areas you should not have a ton of mineral scale inside the washer as long as your detergent is dosing properly. The detergent has water softening agents. As long as the right dose is used any minerals will be bound up and go down the drain. It is also not possible for the TwinDOS detergent to leak into the washer. The bottles are located below the lowest part of the drum. They are pumped into the drum at the correct time and in the proper dose. Dose is determined from the amount of time the pump runs. The pumps have a known amount that they dispense each minute. So if you set a particular dose the pump is run for the amount of time to deliver that dose.
