Filter Combination in Sump
The circulation pump M6 pumps the wash water from the sump via the filter
combination to the spray arms. The circulating wash water is filtered via 2 parallel
paths. A proportion of the water flows through the central opening of the crown
coarse filter and then passes through the conical micro fine filter; see Figure 4-15,
Item 3. The remainder passes directly through the large surface area fine filter; see
Figure 4-15, Item 2, which has a small additional hole to provide a vent for the
circulation pump intake area. All water is then mixed together again in the sump
where it is taken in by the circulation pump and the circuit is repeated. In this way
some of the water passing through the filter system always passes through the micro
fine filter so the proportion of soil particles in the suds is continually being reduced.
Soil that is retained by the micro fine filter either collects there or falls onto the filter
cap where it will eventually be removed by the drain pump.
The crown coarse filter, see Figure 4-15, Item 1, is attached to the filter combination
handle. If dispensed powder detergent should fall into the micro fine filter, it remains
on the filter cap where it can dissolve, instead of collecting in the drain outlet. Foreign
bodies, which pass the crown coarse filter to the micro fine filter collect on the filter
cap and so cannot block the drain outlet.
