The main control seeks the Lower Primary as the
followed by silverware wash, upper spray system
(which includes mid spray arm), bottle wash and
upper spray system. Lower reverse is the last of the
rotation before repeating the full rotation until the
main wash is complete. Silverware wash and lower
reverse are not used in pre- or post-rinse segments
of the cycle. The illustrations below show the sensor
ON or a closed circuit, and OFF or an open circuit as
determined by the magnets on the diverter plate.

Diagnosing a Pressure Diverter
Use a Clear Door (Part #: WX05X20002) to diagnose
a mechanically inoperative diverter.
If a diverter is not changing positions when
the circulation motor stops and starts, and the
dishwasher has proper water level with a normal
spray pattern on the zone that is working, the
diverter is mechanically inoperative and should be
replaced.
A dishwasher that starts and stops every 3 to 10
seconds (3 to 5 seconds for single speed motors,
and 6 to 10 seconds for variable speed motors) may
indicate a bad sensor. If the water changes wash
zones, the sensor, connections or harness may be at
fault. Switches normally open and close when the
circulation pump is on, causing pressure to raise the
diverter plate.
Diagnosing the Diverter Sensor
A magnet can be placed on the end of the sensor to
test the switches. Each switch will open and close
as the magnet triggers the switch. The circuit will
read as open or closed.
1. Access the sensor (see Sump Module Removal
section of this service guide).
2. Push in on the tab to release the sensor and lift
up to remove.
3. Access connector J711 on the main control.
