Fault/Error Code Display Method
Fault/error codes are displayed by alternating the
state of the Status LEDs and display (if exists). All
fault/error codes have an F# and an E#. The F#
indicates the suspect System/Category and the
E# indicates the suspect Component system.
If the Sensing, Prewash, and/or Soak LEDs are
ON, the Fault Number is represented; if OFF,
the Error Number is represented (see example
below). The remaining LEDs (Wash, Rinse, Spin,
and Done) represent the fault and error code in
binary. (See Fault/Error Code Charts on pages 6
& 7 for more information.)
