Bosch 500 Washer not spinning at high rotation Our Bosch Nexxt 500 goes in to the spin cycle, yet it seems as though as the drum is not spinning very rapidly at all. Very little water comes out of the spin cycle, and the clothes are left very wet. Gentle and Extra spin seem to be the same.

possibly the motor brushes.
take back panel off. disconnect motor. remove bolts holding motor in and take out motor. check condition of brushes

Absolutely those dryer sheets are the root of all evil....I would also recommend a good vent brush to clean your dryer vent.
Follow these steps, it worked for me:
1. use a shop vacuum to clean out the dry vent or a vent brush.
2. Clean your lint filter with windex, hot water and and soft bristle brush.
If this doesnt work try running the until disconnected from the vent for a cycle to isolate the vent as your issue.

Cheers!
