The two-port diverter is the key component which
allows low water use, by alternating water to the
lower spray arm or mid spray arm, bottle wash
(some models) and upper spray system.
The lower portion of the diverter is molded into
the sump. Shown below is the bottom side of the
diverter top. Notice the bypass notch in the upper
spray system port.

Operation
1. The “bypass” allows water to bypass the
check ball in the diverter as described in
the next step. The dishwasher is in OFF
or standby mode, no pump operation. The
check ball is at the bottom of the diverter.
2.
The wash pump turns on, water flows to the
lower spray arm, and the check ball blocks
the rear port or upper spray conduit. The
bypass allows low pressure and low volume
water to enter the main conduit, filling the
conduit with no actual spray from the mid and
upper wash components.
