Hi,
I have a 14 month old Samsung front load washer.
It has been fine except for the last 3 weeks it started to vibrate violently when washing towels or bedding.
I researched on Appliance part pros and found that likely causes are bad balance ring, bad shocks, bad Hall effect sensor or MEMS sensor.
So far I have replaced the Balance ring (looked at spider which is in good shape), Hall effect sensor and shocks. I am currently waiting on the MEMS sensor which should arrive next week.

My question is if the MEMS sensor doesn't fix the issue where do I go next?

Also, I can't find any information on how to check for error codes. I have the Service Manual but it is not tell me how to check for fault codes.

Thanks for you help!
Tom
