I will join the old topic, but the cage induction and the magnet induction are maybe a small detail, but a technological gap in the control.
I have an LG DD and I will say that it was torn out of the scrap because it did not go there thanks to me and it has been working for 5 years, the bearings have been replaced and 4 years have passed. Maybe a detail, but LG floods the electronics with gel, which makes servicing difficult because the capacitors in the power supplies die. but it can be repaired ... well, probably lightning bolts in electronics. As for the bearings and gluing the drums, the bearings fall through the water because it's hard and the stone does its job. When I moved to a house where the water is completely soft, the washing machine, despite louder operation, does not deteriorate like the neighbors, the average time from the appearance of the noise of the bearings to the death of the washing machine is about half a year (washing every other day). Confirmed many times because I repair household appliances. For me, soft water and bearings rustle for 3 years, I worked on very hard water for a year and it became audible after a year.
