Cleaning the spray arms
From time to time, particles may
become trapped in the spray arm jets.
The spray arms should be inspected
and cleaned every 4 - 6 months.
Remove the spray arms as follows:
^ Unscrew the upper spray arm.
^ Unscrew the middle spray arm
(under the upper basket) clockwise
at the knurled nut.
The knurled nut has a left hand thread.
To unscrew the spray arm turn the nut
and the spray arm to the right.
^ Remove the lower basket. Pull the
lower spray arm firmly upwards to
remove.

^ Use a sharp pointed object to push
particles into the spray arm jets and
rinse thoroughly under running water.
^ Open the cap of the lower spray
arm, by turning it clockwise, to rinse
out particles.
^ After cleaning close the cap tightly.
^ After replacing the spray arms check
that they rotate freely.
