There is a laundromat just up the street from me that has Electrolux equipment. The best machines they have are the W5130H ones. They are so good at spinning out water that my heavy towels dry in just 25 minutes! Perhaps it also has something to do with the great Electrolux dryers they also have!
Sounded like the Electrolux Wascator W75 started to lose bearings.. Did you ever get a replacement of these machines or replaced bearings by any chance?
If you live in an apartment in sweden u have a local "free laundromaut". I live in sweden. Its the peeople that own the place that take care of everything.
