Miele USA Doesn't Really Advertise The Fact
But they do perform the larger repairs of Miele washers, such as the 10XX,19XX and such series that require motor,motor brush, bearing repair and so forth at their main offices in New Jersey.
As one noted from other European websites, such work most always requires a way to raise the tubs and that cast iron cradle of of the machine, thus the use of a winch or some sort of heavy duty equipment, none of which is likely to be found in most homes and apartments. Cost is a flat $1,500 or so just for transportation, labour and parts are extra, unless of course part of warranty repair.
In the EU and UK, DIY work on Miele unit is very popular, and parts are easily had in most cases from the shops as we do with our American brands. Guess most persons either have or know someone who does have the required equipment, much less the space.
The motor on my washer is also cast iron, IIRC and is quite beefy.
Nine times out of ten when speaking with anyone at Miele they will try to talk one out of having older machines repaired. Even the local service supervisor told me off for wanting to keep a machine that "wastes so much water".
IIRC, the 1918 series had some sort of design fault or problem with their bearings or something in that area. This caused some units to fail before they should have, and perhaps that is the reason Miele USA has the "bearing replacement" workshop.
Rinsing:
These older Miele units were designed to rinse as much froth and detergent away (via dilution of several rinses), before even attempting a spin (the first is only after three rinses and then only for thirty seconds), mainly due to fear of suds lock and stressing the motor.
When washing a heavy load say of bath linen, was advised to use the machine at half capacity as modern thick and thirsty towels hold so much water that at the first spin there can be too much water. In this case my unit simply slows down, but often you can hear the motor and pump getting a workout trying to cope with all that water.
Also think because "boil washing", or at least very high temperature washing was still the norm when these models were introduced, Miele designed the washers to bring down the temp of the wash to decrease the risk of thermal creases. Spinning a load of laundry right after a 200F wash cycle is probably going to put in some wrinkles that no amount of subsequent rinses or ironing will remove.
To be fair,many older Miele washers use their brushes at such a low rate it could very well be >12 years or longer before they require changing, if at all. Often the machine will be junked long before the brushes need to be changed.
Parts on the 10XX series washers and probably their matching dryers are becoming hard to find in the USA. Miele no longer imports supply, and once whatever is in the warehouse is gone, that will be it. This was according to Miele Parts when one had to order things for my unit.
