Product review (4 stars): There was a sound like a belt is slipping
My LG washing machine stopped working. The "tumbler" did not rotate anymore. There was a sound like a belt is slipping. I opened the back and tightened the screw. It worked for half a cycle but then failed again. I did some research on the internet and "experts" suggested a fix which involved taking almost the whole washing machine apart. I decided to take the risk and purchase this replacement part. It turns out that the fix was very easy. There is one big screw in the center. You take that out by wiggling the old part out (it takes a bit of effort as it seems the magnets want to keep it in place). Then you just put in the new part, put the screw back in, put the cover back on and you are done. It's really quite easy.

Note that the failure is because the wheel has plastic spokes that engage with the "tumbler". These plastic spokes broke off so the wheel could not turn the "tumbler" anymore. This new part also has plastic spokes so eventually it will fail again. I read that supposedly there are some wheels with metal spokes. They obviously would last longer but I guess they could also damage the counter parts ("tumbler") which would be much harder to replace. I expect that this new wheel will last a few years so I am fine with it having plastic spokes.
