Circulation Diagnostics
Clear Door Diagnostic Tool
The clear door (Part #: WX05X20002) provides
technicians with a tool to accurately diagnose
2012 and newer dishwashers. Viewing the
wash zones improves accuracy, will reduce
diagnostic time, reduce repeat calls, and will
increase technician confidence. There may also
be situations where the clear door can be used
to show a consumer the dishwasher is operating
properly.
Poor wash results can be due to many different
causes. The clear door allows operation and
visibility of spray arms including rotation, slow or
non-rotation, leaks between wash components,
restrictions, and spray jet pattern.
Proper spray arm speeds have a tolerance of
+/- 5 RPM. The lower spray arm turns clockwise
(CW) at approximately 50 RPM. The mid spray
arm turns approximately 30 RPM counter-
clockwise (CCW).
To Use WX05X20002 Clear Door
1. Place the dishwasher in Service Mode to fill,
circulate and drain. Details on Consumer
Error Mode and Service Mode can be found
in dishwasher mini manuals and in this
service guide. All models have the same
entry directions. Different controls have
different ways to communicate results and
progress.
2. Remove the bottom rack for an unobstructed
view of the lower spray arm.

7. The clear door has a latch strike. When
pushed into the latched position, it will
activate the door switch assembly. The
dishwasher may not start if the door is
installed to low.
8. Initiate Water Valve in Service Mode, the
dishwasher will fill for 60 seconds.

test 30 seconds lower clockwise (CW), 2 to 3
seconds lower counter-clockwise (CCW) (will
not reach full speed unless dishwasher is in
a main wash cycle) and 30 seconds upper
spray system. This pattern will repeat.

for leaks in all areas including between the
conduits and wash components.

inspection and diagnoses.
