I realize this is an old thread but...I bought a new SQ AWN432 last August, its been doing the same thing the original poster spoke about, every load, when it goes into spin the tub starts banging around violently. .I had service come out and they took the front cover off and proclaimed all was well and I'd have to babysit each load. A week later I called them back, the clothes canot be redistributed, the banging continues. Service comes back removes front cover and watches it spin violently, tells me the friction ring is almost gone and under the machine is piles of what looks like cornstarch....they returned two days ago and replaced friction ring, base plate, and milk stool, ...I noticed the old friction ring was maybe 1/4 in thick if that and the new one was much thicker...as they placed the machine on top of the new baseplate and F ring...I noticed the F ring slid out of place but they said it was fine as it would slide back into place. What do I know lol...they did not stick around when they were done. It spins just fine now except there's a loud vibration sound during agitation and spin. I had no vibration when I bought this machine. Any ad ice or tip on how you think I should proceed here what could be causing this loud vibration? Thank you much...
