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
At the beginning of the main wash, the dishwasher checks the temperature of the water, and if it is
below 90°F, then it will add up to 10 minutes of time to heat the water to 90°F by circulating the water
while the heater is on. Similarly, at the beginning of nal rinse, the dishwasher will check the water
temperature, and if it is below 105°F, then it will add up to 15 minutes of time to heat the water to 105.
Once it reaches the target temperature, any remaining hot start time will be truncated and will continue
on with the cycle.
The cycle chart below explains the segments of a cycle (cycles for all models included, not all
models contain the same cycles). It details ll and drain times which depend on either a full or partial
drain. It provides the circulation time in each segment, but does not include turbidity or temperature
adjustments or dry cycles (see the Dry System section in this guide). Times will vary depending on
turbidity response and incoming water temperature.

Troubleshooting
• Check voltage input to the dishwasher.
• Verify door switch operation, consult Consumer Error Mode, in the Electronic Controls section of
this service guide.
• Door must be closed within 5 seconds of pressing Start Pad (Safety Feature).
• Check the main board Service LED (see Main Control Diagnostics in Electronic Controls).
• Verify that the dishwasher is not in Demo Mode. Please refer to Demo Mode 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.
This troubleshooting section is an overview of diagnostic capabilities of the electronic control. The
control features also allow retrieval of fault codes when Consumer Error Mode is initiated; operation of
loads is achieved in Service Mode.
Details on Consumer Error Mode and Service
Mode, as well as Service LED are located in the
Electronic Controls section of this service guide.
Single mounting screw
If the control beeps and some LED's ash, this indicates the dishwasher door may be in the open
position. If the User Interface (UI) is ashing all the LED's or the Display (some models) is ashing, this
is an indication of a tripped CSM and the dishwasher is non-responsive, all the LED's will ash until the
CSM is reset. CSM diagnostics are covered in this service guide.
Flashing Lights
Will Not Start
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, refer to Demo Mode section of this guide.

– 14 –
Critical errors will turn a cycle off and show a display alerting the consumer of a fault which will not
allow the dishwasher to function or cause an undesirable condition.
No Water Detected
In the event the internal water level does not change, the cycle will be cancelled and the user interface
will display the following:
• Models with SSD (Seven Segment Display) Screens: H20 will be displayed on the SSD screen.
• Models without SSD Screens: Wash Temp LED will blink continuously.
The water may be turned off. The consumer is directed to verify the water supply line is connected
properly, the supply line valve is turned on, and then restart the cycle. If this fails, the consumer is
directed to call for service.
Pressure Sensor Errors
In the event that the pressure sensor signal is undetectable or irrational, the cycle will be canceled and
the user interface will display the following:
• Models with SSD: PrS or PrF will be displayed.
• Models without SSD: Dry LED or Wash Temp+Dry LEDs will blink.
The control does not see a change in pressure during ll. Verify pressure sensor harness, then replace
the pressure sensor if needed.
Continuous Fill Error
In the event that consecutive signals from the pressure sensor detect high water level, the drain pump
will run and the User Interface (UI) will display the following:
• Models with SSD Screens: CFE will be displayed on the SSD screen.
• Models without SSD Screens: Cycle Indication LEDs will blink continuously.
The consumer is directed to turn off the water supply. Diagnose reasons for the water valve not
shutting off.

The Tub and Structure section of this guide will
cover the toe kick, junction box, racks, leveling,
door balance, gaskets, trim (some models), main
control board, door, door components, as well
as the removing and separation of the screwless
appearance door. It will also cover the sump
module and removal. Details of the sump
components will be covered in the Circulation
System or Drain System sections of this guide.
Some models include tub trim, which clips to the
plastic tub to reduce sound levels and provides a
cleaner appearance to the installation.
If the cutout prevents the dishwasher from being
fully installed, or if the trim rolls inward preventing
the door from closing, it may be trimmed to
t properly. The wiper edge must contact the
cabinet to be an effective sound barrier.
WARNING: GE Factory Service Technicians
are REQUIRED to follow Lockout / Tagout
(LOTO) 6 Step Process prior to beginning
repair.
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.
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
