Fault Indication - GE Monogram ZBD6400 Series Technical Service Manual

6000 & 7000 Series DISHWASHERS

4.0 FAULT INDICATION

4.1 Models 6400/6500, 6700/6900, 6905, 7000 Series.
To assist with the diagnosis of dishwasher faults, any faults
that are detected during a wash cycle are saved in nonvola-
tile memory. These fault codes can then be accessed later on
during a service call.
4.1.1 Fault Identification methods for faults detected
during a wash cycle:
If a Not filling and/or Not draining fault is detected during a
wash cycle, then the respective fault codes are to be dis-
played when detected, and remain on if the door is opened.
If a Not Filling fault code is detected during a wash cycle, then
the China Crystal or Light Wash LED will flash, at a rate of 0.5
second on, 0.5 second off.
If a Not Draining fault code is detected during a wash cycle,
then the Rinse Only or Sani Wash LED will flash, at a rate of
0.5 second on, 0.5 second off.
These fault codes can only be cleared from the display by
pressing and holding the START/CANCEL button for 3 sec-
onds at the end of the wash cycle, or by starting a new wash
cycle. (The fault codes stored in nonvolatile memory will not
be cleared).
4.1.2 Other Fault Identification methods:
Activating the Fault Indication mode:
If a fault has been detected by the Field Test Cycle, or by the
Factory Test Cycle, then the Fault Indication mode will be
automatically activated, and the fault will be reported as
indicated below.
To manually recall the saved fault codes, press the buttons in
the following sequence:
