Yeah, I wouldn't take a machine apart - at all - electrical safety in particular, and too much potential for mechanical issues or safety.
I have continued on the tests and looking at a rough matrix of issues, and pitting them against pages and pages of user' s data on the forums. If I exclude genuine cases where holes occur from over spinning, moths eggs, belts, zips, detergents, granite bench tops etc, and valid comments from engineers, poor quality weave etc., I find firstly there is too much evidence to ignore, this is a real issue, and as there is no definitive answer it causes frustration and tears over loss of hundreds of dollars in new clothing damage, let alone attachment to favourite clothes, and that as the cause exists in the machine, it is hidden, that's why we can't capture it.
All it takes is one mechanical part or rough edged hole, or other mentioned possible causes, like worn out bearings to continually destroy garments, just one, and as the mechanisms are all hidden from sight we don't get the answer. You'd basically need a team of NASA scientists to design a machine that produces no holes! What I am therefore saying is the problems won't go away unless the owners, i.e. the manufacturer designers, FIX IT :-) so, in the context of what I mentioned above, I have found no holes if I wash, spin, or dry, at 600rpm. I have by the way a top brand machine. And I suspect my machine has only one tiny piece somewhere doing the deed as it is consistent, and not multiple hole types.
I believe certain fabrics are weaved in a way to be more susceptible. Even a firm cotton weave of a business shirt can eventually get one of these ripped holes. The holes always have the same shapes in my case in particular directions with the weave, and holes to the side of the garments near stronger areas of the shirt's construction are always a bit smaller. I have two cheap T-Shirts that actually have a finer stronger fabric weave, and one has a hole located to the side join area, rather than the general area of the shirt.
I can see where fabric patterns are maintained with the rip, rather than eaten by a hole. My new jeans at 900rpm show an attempt at a hole, but I can't prove that, and somehow parts of the shirts are more frequently in the zone for a hole, which suggests to me we don't really understand the way clothes tumble according to weight distribution and shape and what happens during the "destruction" process. As it is in my view the machine at fault, it is not correct to say that because holes aggregate in certain areas of garments that it is not the machine.
I have one example where I can see threads actually pulled, and I think this is where the fabric resisted the rip due to the location with a second layer of fabric underneath it.
My matrix basically indicates shows the following.
Mostly T-Shirts, but also other fabrics and garment types.
Usually in similar areas of T-Shrts, but not so with other garments.
I suspect it happens to sox. I've had almost new high quality sox with suspect holes that don't make sense.
Have not seen it with my brand of u-wear.
I did not notice holes in the initial life of the machine. It seems it has escalated to an unusable point now.
Will occur on expensive brands without me wearing the shirt first, as I wash first after purchase.
I thought it possible for friction on surface and effect of spattered cooking oil, but the holes on night shirts are also present and they are only worn when I go to bed, and on new shirts washed before wear, all purchased from differing department stores.
As said, holes on new shirts not worn first, so that debunks unfortunately the idea of the friction at the gym with weights etc.
We obviously are not imagining this.
My current conclusion is to put up with 600rpm which I really do not like, until I can afford to replace the machine. I am too hesitant to get an engineer to replace seals, font door, and drum, and bearings, or to expect resolution with the supplier after all the customer testimonials on that aspect. The forums provide very helpful suggestions, but even after all that, there is this ongoing category of damage. If your neighbour doesn't have it, simple, it's mechanical. I learnt in computing after many years experience, if it is hardware, the problem never resolves itself by itself, and grows worse.
I don't see a fix to this without consumer enforcement on the manufacturers. Statistically, a certain number of machines will behave a certain way, just the same as any other commercial product. If anyone has holes within the first week of a purchase I would personally consider asking a full refund or exchange on the grounds of dissatisfaction, rather than guessing, hoping, or extending a discussion with a supplier. The damage to my few amount of clothes would be up towards $1,000. There is nothing in my "matrix" to show this is just one thing or another, other than the machine, and because we can't see it with cameras! we have the many many consumers who have statistically proven it, but who can't visually prove it. This is why the forums reach a stale mate, reading the same frustrations over and over. If I learn any more I'll add a post. Cheers, Laurie
