and unscrew the spindle bearing pin. The wash arm can
then be lifted off the spindle.

Final Rinse Arms and Nozzles
The rinse nozzles will need frequent cleaning if the water
supply is considered “hard” and contains dissolved solids
such as calcium and magnesium.
Obstructions in the lower rinse arm nozzles can be cleared
using an opened paper clip or similar object. Push the
obstruction into the rinse arm, then remove the end caps
and flush out the tube.
The lower rinse arm can be lifted straight off the bearing
pin and thrust washer assembly.
The upper rinse nozzles can be cleared by using an opened
paper clip or similar object. Push the obstruction into the
rinse arm. Remove the rinse nozzle closest to the end and
flush out the line. Reinstall the rinse nozzle when finished.
