Does anyone know- from an engineering standpoint- if it is more difficult to balance a load of wash in a front loader with a tilted drum vs a true horizontal axis drum? | ||

I would say, that Tilted drums could add to balancing problems, the load will have more weight at the back, meaning motor could think out of balance and give a balance re distribution. Saying this, smaller loads could balance faster. | ||

Tilted FL Washers Do seem to have more balance problems, but the real problem is light to SEVERE tangling with a tilted tub. The only reason to tilt the tub is it makes loading and unloading easier and makes the machine more attractive to buyers worried about bending over to load and unload. No serious FL washer would ever be built with a tilted tub and I would never buy one. | ||

Hhmmmm
I`m sure the Hoover doctrine can quote different as well!!!
Having used the first of the Keymatic tilted drums, I must say it tends to balance heavy unusual loads very well, IMHO its nothing to do with tilted drums as to how they spin best, its how the suspension works as well, tilted drums work best with the drum hung from the top cabinet by heavy springs and cast weights..... Also when the spinning laundry is pinned more to the back of the drum in the tilted drum, the spinning weight is nearer the low point or fulcrum of the drives energy...I wonder if that helps??, whereas a horizontal level drum has a spinning weight further away from the energy point...AND if its not "Spirit Level" and tilting forward then more of the weight is right at the front (or furthest point) of the drive energy... Its like a top loading spin dryer when clothes are packed evenly lower and tighter near the base then they tend to spin better and not OOB.. Does that make sense or have I been having too many hot toddies...!! | ||

It does make sense. Shaft being the fulcrum, farther from that increases moment.
However, having watched/used the slant Westinghouse for years and the horizontal Frigiwhite since 1998 I really see little appreciable difference between them except how far I have to squat down to unload the horizontal drum. | ||

Very good point Mike
The moment is reduced the closer the load is to the shaft-(driving member). Westinghouse actually designed the front loaders to tilt down to the horizontal when loaded with clothes and water. And as it drained the tub tilts back up for spin just so that the load is distributed across the dome at the back near the shaft!
Its all in their patents. | ||

I have a 2009 KM Elite FL (and a MT Neptune FL) with the tilted drum and I completely agree with John (Combo52) on the tangling problem. The Neptune FL doesn't seem to tangle as much the KM Elite, but it has happened. Maybe because it uses a lot more water?
My dad lives with me so I do his laundry every week. Between his long sleeve shirts, PJ's and pants, I ALWAYS have to stop the KM Elite washer and untie the knot ball at least once, if not twice during the cycle. When I see it taking a long time trying to balance and re-balance, I know it's time to untangle the knot-ball again. (I try to avoid washing these items in the '55 Unimatic for the same reason.)
