suds flow through the microfine filter. Soil that is retained by the microfine
filter either collects there or falls onto the filter cap where it will eventually be
flushed out by the drain pump.
The crown coarse filter (Figure 050-15, Item 1) is attached to the filter
combination handle. If dispensed powder detergent should fall into the
microfine filter, it remains on the filter cap where it can dissolve. This prevents
it from collecting in the drain outlet. Foreign objects which pass the crown
coarse filter to the microfine filter collect on the filter cap and so cannot block
the drain outlet.

Drain Pump

Drain pump M8 is driven by a synchronous motor and is located under the
cabinet on the left next to the sump. It is directly activated by the electronic. In
case of fault, drain pump M8 can be directly activated via overflow float
switch B8/3. The drain pump pumps the suds via the non-return valve and the
drain hose to the on-site drain.
Drain pump M8 extracts water from below the microfine filter. This reverses
the direction of flow through the microfine filter that normally exists during the
dishwashing cycle. Soil particles that have been trapped in the filter during
dishwashing are then flushed out with the drain water.
Pump capacity:
Max. 13'1" hose length
Max. 3'3" head height
Most faults will cause the program in operation to be interrupted and the drain
pump to start.
If the WaterProof System has been activated (Fault Code F70, Section 080-3.36),
the drain pump continues to run even after the appliance has been shut off. In this
case, the pump is switched off only when the main power cable is unplugged or by
removing water from the drip pan.
