Repair of Bosch washing machine WFK-2401?

Bosch WFK2401 pumps water out, but motor does not turn drum. Entered diagnostic mode. It returned 08: motor won't turn. Not very helpful. We know that. Trying to determine WHY motor won't turn. Belt is good. Have back off of machine, but can't determine how to release top of machine for more investigation. I have multi-meter and am comfortable with electrical testing. Any idea of suspect part that would keep motor from engaging? It is NOT frozen...Turns freely by hand.

Check the pressure switch -the system that determines correct water level in the drum. Its a round item about 3 inches across with several wires connected, it sits under the top cover. Its an air operated switch which tells the machine water has reached the correct level. Disconnect the thin rubber pipe from the switch and blow down through it to clear any blockage. Switch itself may be faulty but its more likely the pressure pipe or the vessel attached to the other end of the pipe is blocked. Could also be a pump fault?
Disconnect pump from sump hose and check for obstruction in either item. Pump removal: power off, remove cover, locate pump, (attached to other end of drain pipe).undo 2 wiring connections, 2 hose connections, and pump mounting screws. Remove pump chamber - some are held in with screws, others clip into place. Check for foreign objects round the impeller. If pump chamber is clear, may be a fault with the pump motor - in which case, replace.
