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 not only allows more accuracy, it
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
things. 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). The upper sprayer cannot be
counted but can be viewed for proper operation.

1.
Place the dishwasher in service mode to fill,
circulate and drain. Details on Consumer
Error Mode and Service Mode can be found

directions. Different controls have different
ways to communicate results and progress.

seconds lower counter-clockwise (CCW) (will
not reach full speed unless dishwasher is in
