3.4.3 Filter Plate
The filter plate is a stainless steel disk positioned below the
dish rack and spray arm and completely encompasses the
base of the tub.
The drain filter has a rubber over mould around the edge
to reduce soil re-depositing. Between the filter plate and
rotor an o ring is also fitted to ensure a tight fit to reduce
water leaks. These improvements will ensure a better wash
performance.
The drain filter fits tightly into the filter plate, due to the
rubber over mould around the edge.
3.4.4 Drain Filter
The tub has vanes that swirl the water around and over the
filter plate. At the front of the tub, located as part of the
filter plate, is the drain filter.
The drain filter is secured into the filter plate over mould
which helps sealing.
Large soils collect in the drain filter and only smaller
soil flows through its micro-mesh filter, eliminating
re-depositing of soil during the wash.
The drain filter should be regularly checked and cleaned.
