Wash Cycle
Water and debris flow from the tub,
into the sump chamber (1). A metal
impeller blade pulverizes the larger
debris as it moves through the nut
grater (2) and upward (3) towards the
lower spray arm.
A portion of the water carrying debris is
diverted from the spray-arm path and
moves through the filter coupler (4),
into the fine filter (5), and through the
fine screen (6) which traps the debris.
The debris tumbles down the incline,
passes through the check ball coupler
(7) and settles at the bottom of the
collection chamber (8).

Drain Cycle
Water and debris flow from the tub
into the sump chamber (1), through the
metal impeller blade of the nut grater
(2) and upward toward the lower spray
arm.
2. The drain solenoid closes the drain
valve (3). Water is directed into the
bypass drain connector (4) and moves
into the collection chamber (5). Water
pressure pushes the filter check ball (6)
upwards, closing off the passage to the
fine filter.
3. Water and collected debris pass
through the drain hose connection (7)
and are discharged through the drain
hose.
