Good for Tolivac, practicing your Second Amendment rights. When all other amendments are suspended, you can always reach for the Second to get the rest of 'em back!
Toggleswitch, I think Whirlcool's suggestions are good. I'm sure they'll replace the unit under warranty.
Re. those flying spin-mats: I can't imagine how they'd get loose unless the spinner was vibrating like crazy from an offbalanced load. There should be an edge around the interior of the spinner, and the spin mat should be just a tad larger so it stays in there under the edge. I don't recommend omitting the spin mat; anything that can get loose will, i.e. including shirt sleeves.
Re. The7 re. 50 hz vs. 60 hz: How does an increase of 20% in speed translate to an increase of 40% in G-forces? (Here's me setting myself up for a most un-geek-like embarrassment for missing some obvious law of physics, or maybe you're mistaken?) In any case, I always regard such instances as guinea-pig tests until/unless they prove out. That is, if I buy one of those English micro-twins and run it on 60 Hz, I'm not going to freak out if it self-destructs; after all it was a guinea-pig. But if it works, great.
Re. SpinX: These things are made in the USA in limited production runs, that's why they cost as much as they do. But with the price of natural gas (for the tumble dryer) going through the roof, they should pay for themselves more quickly now. I expect to be designing a communal laundry for a small cohousing project in a couple of years and will spec a Spin-X and put a coinbox or card-key on the tumble dryer, so people will see they're saving money when they save energy.
Last but not least: There is presently a commercal extractor on Ebay; do your search for "clothes washer" and look for the obvious product title that comes up. Presently has 3 days to go.
