The Octopus mirror rinse uses two - four nozzle spinners on the PS & DS. If the arms are not spinning check for the following:
- Check the nozzles for wear -- The nozzles may be trying to push more water than what the pump could handle. Replace the nozzle and test the unit.
- Replace the swivel -- The swivel that makes the arms rotate could be defective. Replace the swivel and test the unit
- Make sure that there is enough pressure to run the arms -- the recommended pressure is between 600-800 PSI
