Operation and Cycle Information
This section of the guide provides details on segments of cycles, timing of cycles, temperature expectations,
and cycling of the heater during the dry portion of a cycle.
Auto Hot Start
If the incoming water temperature is below 80°F, Auto Hot Start is initiated at the beginning of the cycle in
an attempt to purge the home water lines of cooler water. Auto Hot Start can add up to 10 minutes to cycle

segment of the cycle.
Cycle Times
Cycle times will vary depending on options selected, incoming water temperature, and soil level (some
models).
Incoming water temperature of 120°F to 140°F is recommended. The 4 pass heating element quickly heats
the water for optimum performance.
The cycle chart below explains the segments of a cycle (cycles for all models included, not all models contain

NOTES:
 The previous chart has maximum segment parameters listed. The control will bypass some rinse cycles
if the turbidity sensor detects lower soil than the selected cycle maximum parameter and temperature
targets are met.
 Selecting the Wash Temp option(s) will add 5 minutes to Pre-Wash 4 (PW4) and Post-Rinse 1 (PR1). This
extra time is used to heat water.
 The Steam option will change the segments Pre-Wash 4 (PW4), (increasing heater operation).

Troubleshooting
Service LED
 Check voltage input to the dishwasher.
 Verify door switch operation, consult Fault Code Mode.
 Start pad must be pressed within 5 to 10 seconds of closing the door (Safety Feature).
 Check the main board Service LED (see Main Control Diagnostics in Electronic Controls).
 Verify that the dishwasher is not in demo mode (see table in Main Control Diagnostics in the Electronic
Controls section of this guide).
 CSM (Current Sense Module) tripped. Please refer to On the Main Control Board CSM in the Electronic
Controls section of this guide.
Symptom: If the dishwasher is “dead”, no LED operation, no button operation or beeping occurs.
Diagnosis: Attempt placing the dishwasher in Consumer Error Mode.
Cure: The CSM (Current Sense Module) is tripped and must be fully diagnosed. Refer to On the Main Control
Board CSM section of this guide.
Symptom: If the start button either does not respond or it makes a triple beep sound every time it’s pressed
AND all other buttons respond as normal.
Diagnosis: The dishwasher may be in demo mode.
Cure: To exit demo mode, hold “START” and “HEATED DRY” at the same time for 5 seconds.
Flashing LED's or Displays (some models) are an indication that the control is waiting for a start command or
that the door is in the open position. There are no fault codes that will automatically display or cause a no-
run condition. If board communications are an issue, look for a fault on the main control board Service LED.
All of the above diagnostics are covered in this service guide.
Flashing Lights
Will Not Start
This troubleshooting section is an overview of the diagnostic capabilities of the electronic control. The control
features allow retrieval of error codes, operation of loads in service mode and further diagnostics of the
electronic controls with the use of the Service LED on the main control board. Details on Consumer Error
Mode and Service Mode, as well as Service LED are located in the Electronic Control section of this guide.
To view the Service LED, disconnect power, lower the control box bottom cover and reapply power to the
dishwasher when the control is in a safe position.

Tub Trim (some models)
Some models include tub trim which clips to the
plastic tub to reduce sound levels and provides a
cleaner appearance to the installation.

WARNING: GE Factory Service Technicians are
REQUIRED to follow Lockout / Tagout (LOTO) 6
Step Process prior to beginning repair.
Toe Kick
The toe kick panel is a safety and decorative panel
covering the machine area of the dishwasher. The
panel provides a safety barrier, closing the front of
the dishwasher machine compartment. To remove
the panel, remove two 1/4 in. hex head screws and
pull the panel away from the dishwasher.
Junction Box and House Wiring Connection
The junction box is located behind the toe kick on
the right hand side of the dishwasher. The junction
box is where the 120 VAC house voltage connects to
the dishwasher. The dishwasher may be hardwired
or an optional cord may be installed (available
separately, Part #: WX09X70910), which plugs into
a wall outlet and connects to the harness plug into
the control (see the Installation Guide provided with
the appliance). The cover is held in place with a 1/4
in. hex head screw on the left side, and tab on the
right side. To remove the cover, remove the screw
and pull out and to left to release the tab. It is helpful
to squeeze the top and bottom of the box when
removing and installing.

door to be removed while the dishwasher remains

Information on door removal can be found under
the Door section later in this guide.

1. 1. Use bottom
nut to level the
dishwasher
2. Tighten top nut
to make leg

Leveling Legs
There are four leveling legs located on the base rails
of the dishwasher.
To access the level legs, remove the toe kick and
insulation (some models). To raise the dishwasher,
turn the level legs counter clockwise.
If a level leg will not keep the dishwasher level
because the support rail is stripped, the dishwasher
may be repaired by using two 1/2 in. hex nuts with
1/4 in. with a - 20 thread size as jam nuts. Rear level
legs have the optional location to repair.
Place one nut on the leg and install the new leg onto

Door Balance System
The door balance system is comprised of springs,
cables, rollers and hinge arms.
Door Springs and Cables
The spring is adjustable as it attaches to the rear of
the leg base assembly. There are two holes in the
leg and factory setting on a support screw. Higher
connection on the rear frame on the leg causes
more tension on the spring. The spring connects to
a cable which connects to the hinge arm using a
roller as a tensioner.
