Replacing the motor (also from Appliancepartspros.com solved the 3E. On my Samsung washer the error code was to the hall sensor, which on this washer is integral to the motor and cannot be purchased seperately. That fixed the code. The balancing seems better with the dampers. Washer is about 7years old and HE front loader. 10-15 minutes of disassembly, 15 minutes each for the motor and re-installing dampers, and 15 minutes to re assemble.
