Samsung out of balance empty

I have a Samsung Front load washer that recently started to have balance issues.
It appears to mainly happen when set on Towels or Bedding setting.
I have so far replaced the balance ring, Hall sensor and MEM sensor but no change in performance.
I have noticed that even if I run the unit on without anything in it the machine can’t balance at low speed and bangs loudly until it spins up to speed. At high speed it spins fine.

Does anyone have any ideas on where I should look next?

Thanks
