Filtration - Haier GE GDF510P M4 Series Service Manual

Filtration

Good filtration is key to good wash performance.
The ultra-fine filter is consumer removable with a
twist lock design. The Owner's Manual advises
the consumer to remove and clean every 60 days
or more frequently depending on use.
NOTE: Using brushes or scouring pads will
damage the filter. To remove, turn the filter
counter-clockwise (CCW) and lift from the sump.
Ultra-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.
Fine Filter
Water is filtered as water flows through both 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 and out
the drain port.
