CARE and CLEANING
The Bosch dishwashers have a triple filter system
comprised of: a microfilter, a fine filter and a coarse filter.
The microfilter is self-cleaning, but the coarse filter and
fine filter will sometimes be found to have collected items,
fix)m bones to toothpicks or straws that been left on the
plates or in the glasses. For this reason the following
maintenance should be observed:
■ Filters
The filters should be checked on a regular basis. To
remove the filters, turn the knurled ring handle of the
coarse/microfilter ' A turn counter-clockwise, see figure
14, and lift out the coarse/microfilter. After removing
the coarse/microfilter the fine filter can also be lifted
out for inspection. Examine the filters. If large solids,
such as bones, or laige seed(s) are present remove the
filters and dispose of the large solids by emptying into
a waste basket. If any other items have been trapped
by the filters, paper labels for example, these should
also be removed while you have the filters out of the
dishwasher. These smaller items can usually be flushed
out under running water if you have trouble removing
them by hand.
After cleaning, reinsert the filters in the dishwasher
making sure to press the filters firmly into position,
and then turning the knurled ring
A turn clockwise
until locked. Pull gently on the knurled ring to make
sure the filters are again locked in place.
Other areas requiring periodic maintenance are the wash
arms and the stainless steel tank and inner door and door
gasket:
■ Wash arms
The wash arms should be checked on a regular basis
to assure that the spray orifices are clear and
unobstructed. If the wash arms require cleaning they
are easily removable:
Figure 15.
> The lower wash arm simply snaps into place and
can be removed by pulling upwards.
> The upper wash arm is held in position by a locking
ring that can be released by turning it approximately
1/8 turn. See figure 15.
After cleaning, reattach the wash arms by reversing
the action used to remove them.
■ Stainless Steel Tank and Door
The outer edges of the inside door panel should be
cleaned on a regular basis to remove food particles
that can gather there from normal loading. If spots
begin to appear on the stainless steel door or tank
check to make sure that the RINSE AGENT
RESERVOIR has rinse agent in it. Also it is possible
that the wash arms are blocked, which prevented the
door as well as your dishware from being properly
washed and rinsed. Check the wash arms to make sure
they are moving freely. If not, clear the obstruction
away so that the arms may rotate freely and then
rewash the load of dishes in the dishwasher.
Spots that appear on the stainless steel door may be
removed by wiping gently with a sponge sprinkled
with a stainless steel cleaner. Do not use metal
scouring pads to clean the stainless steel surfaces
as these can scratch the surface and leave metal
fragments that can rust.
■ Door Gasket
The door gasket should be cleaned on a regular basis
to remove food particles that can gather from normal
loading. If necessary clean the door gasket using a
damp cloth.
