My Samsung F Loader will spin without clothing, it attempts to reposition/balance but when the RPMs start to ramp up it recycles back up a few mins (from 14 back to 19 for example, or from 8 back to 11, pending the wash spin setting selected). Drain works, clean. I'm guessing it's that the shocks are worn (every 4 years +/_) or the spider arm is cracked due to the Galvanic shock of the dissimilar metals in the spider arm (high Zinc content = sacrificial "anode") and the stainless drum ("cathode"). These arms are notorious for failing, as if it was a manufacturing flaw in using poor metal in the spider arm, or intentional design flaw to sell more washing machines (built in obsolescence). Shocks are $35 (amazon) or up to $80 - $100 for OEM. Spider arm = $125 new/reclaimed to $200 NIB (note you will need screws & thread lock, sold individually oem) Shocks 1 hour repair Spider arm 1 day repair (complete disassembly required), at least 1 of my days. Why no mention of these potential well known problems, as if they want you to replace everything before you get to the problem.
