Samsung front load washer WF365BTBGWR/A2 balancing problem

Hi everyone,

I have a problem with Samsung front load washer WF365BTBGWR/A2. It is 6 years old. Over last several months it became unbalanced during spin cycle and started to vibrate. One day, there was a very loud noise (like explosion) inside during medium speed spin, so I turned it off and took apart. The top balancing weight broke into 2 pieces, and one piece fell down jammed between the side wall and plastic tub. The bottom piece also broke in half, was still in place, but also had multiple cracks. I took the entire machine apart, replaced the balancing weights, both bearings, and the oil seal. Bearings actually did not look bad. After I put it all back together it has become much better, but the problem is that it still vibrates during spin, especially at some intermediate RPMs.

I see that during wash and light spin the metal drum "shakes" as it is out of balance. This is visible even if I just turn the drum by hand if I look at the edge. I don't think I had this issue before, so something must be wrong. However, I did not see any other visible damage putting it together. The bearings are new, the shaft seems straight, the drum looks round, and all supports seem ok. I noticed that when I was putting the tub together the metal drum inside spins without any shakes if I take the large plastic white ring off of it. If I put it on, I feel that it becomes unbalanced.

The plastic ring on the front of the metal drum apparently is another balancing ring. The one I have seems to have rollers inside, some others have fluid. The rollers seem to roll and make some noise when I tilt the ring, but I can't take it apart, it is all sealed. There is no visible damage to it, but if I spin the drum by hands, I hear the rollers move around.

How can I figure out why my metal drum is unbalanced at intermediate RPMs? The problem with this unbalancing is that the machine spins fine only with very light load. If the load is a bit bigger (even half tub) it vibrates and shakes at medium spin.

Thanks.
