User Interface (Ui) Diagnostics; Main Control Diagnostics; Sabbath Mode/Door Wake Up Mode; Consumer Error Mode - Haier GE DDT700S N0 Series Technical Service Manual

User Interface (UI) Diagnostics

No display or LED's will light.
Check for 120 VAC entering the main control. If
no volts are found, check the home breaker. If
main control has 120 VAC, check to see if the
service LED on the main control is flashing. If no,
replace the MC board. If there is a flash, check
the door harness and connections. Replace the
User Interface (UI).
If any of the mentioned LED's illuminate, it
indicates the fault condition is present. These
fault displays cannot be cleared manually; they
will be automatically cleared by the control when
the fault condition is no longer present.
ANY KEY PRESSES OTHER THAN CYCLE
SELECT WILL EXIT THIS MODE.

Main Control Diagnostics

The Service LED has a continuous flash which
only advises the main control has power and the
control software is operating.

Sabbath Mode/Door Wake Up Mode

To turn this option ON/OFF, press and hold the
Start and Boost pads for 5 seconds, close the
door and wait 3 minutes for the dishwasher
to go into sleep mode. In the OFF mode, the
control display, control sounds, and interior lights
(on some models) will not respond to the door
opening/closing. This mode can be used when
observing certain religious holidays such as the
Sabbath. To activate the control and interior
lights (on some models), press any pad.

Consumer Error Mode

To Enter Consumer Error Mode: With the
dishwasher in Standby Mode (not running a
cycle), press and hold the Cycle Select or furthest
button on left (some models) and Start buttons
simultaneously for 5 seconds.
On entry into the Consumer Error Mode, the
control reports the door status for 10 seconds.
• All LEDs are solidly illuminated, if the door is
detected as closed.
• All LEDs are flashing, if the door is detected
as open.
• The SSD (Seven-Segment Display) will
indicate the User Interface (UI) software
version (without a decimal). For example,
software version 8.08 will display as 808.
After the door check, the control will enter a mode
to display any error codes that are currently
detected by the control.
