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, from bones to toothpicks or straws that been left on the plains 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/rnicrofilter ¼ 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 large 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 knuded ring Y4turn 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.
