not clogged and that no food waste or
foreign object is stuck to the spray arms.
If there is any clogging,remove the spray
arms and clean them under water. To
remove the upper spray arm undo the
nut holding it in position by turning it
clockwise and pulling it downwards.
Make sure that the nut is properly
tightened when refitting the upper
spray arm.
