Weird situation with the washer. This washer drains fine, spins fine when nothing is inside. But when anything is in the drum, it skips the spinning cycle.

When I run the cycle with nothing, or spin with nothing, the drum spins very fast and complete a cycle.
But if I put even one single towel into the drum, then the cycle skips spin (complete rinse, then jumps directly from 15 mins to 1 mins).

I have checked the rotor position sensor, strator, hoses, water level gauge, pumps. All fine.

Anyone else seen this?
