Fine Filter - Haier GE GDF450P R0 Series Technical Service Manual

Fine Filter

The fine filter is located on the sump assembly
and should be cleaned each year or as needed
for optimum performance. To remove the fine
filter, remove the ultra-fine filter and lift the front
of the fine filter to release it from the rear tabs on
the sump.
Water is filtered as water flows through both the
fine and ultra-fine filters. Clean filtered water
provides for improved washability.
The fine filter water path is shown below. Water
passes through the fine filter and flows on the
outside of the ultra-fine filter; passes through the
turbidity sensor and into the circulation pump.
The ultra-fine filter water path is shown below.
Water enters the top of the filter, into the sump
and through the ultra-fine filter mesh screen.
The water mixes with the water that has passed
through the fine filter, passes the turbidity sensor
and into the circulation pump.
When the dishwasher drains, water is pulled
through the ultra-fine filter to help clean it, then
out of the drain port.
