Sump Assembly
The sump assembly consists of the fi lter assembly,
micro-fi lter, sump clamping nut, sump gasket, and
sump. The fi lter assembly prevents large particles
from reaching the micro-fi lter and the micro-fi lter
prevents small particles from reaching the sump.
The fi lter assembly rests above the sump and the
micro-fi lter sits above the sump basin. The clamping
nut holds the sump gasket and sump to the bottom
of the dishwasher. The fi lter assembly, micro-fi lter,
and sump clamping nut are accessed from inside
the dishwasher. The gasket and sump are located
under the tub in front of the motor pump assembly.
