Service Mode - GE GDWT668V Technical Service Manual

Service Mode

The dishwasher is programmed with a service mode to aid the technician in troubleshooting it. Each
component can be cycled to detect if it is functioning correctly. Components are cycled by pressing buttons
on the control panel.
To enter the service mode:
• Put the dishwasher in standby mode.
• Press the HEATED DRY and SELECT CYCLE buttons simultaneously.
If performed correctly, the control board responds with two beeps, and all LEDs illuminate for 4 seconds. To
exit the service mode, press the START/RESET button at any time. The dishwasher will automatically exit
service mode if the control panel is inactive for 5 minutes.
Service Mode Control Operation:
When a control is activated in the service mode, the output continues to remain active until the maximum
time has expired or another button is pressed. Once the water valve is activated, the microprocessor must
perform a drain cycle to pump out the water before exiting the service mode.
Control Replacement/Calibration:
The dishwasher enters into the test/00 calibration mode when the unit is fi rst powered on. The door must be
closed and latched. Wait approximately 6 minutes for the second fi ll before canceling the cycle by pressing
the START/RESET button. The dishwasher will be ready to operate after the water is pumped out.
