2 OPTIONADJUSTMENT
2.1 Changing Setup Options
To enter the option adjustment mode, press POWER to turn the LCD on, then
hold the ECO button and KEYLOCK button simultaneously for 5 seconds,
ensuring that ECO is pressed first. Once the option adjustment mode is
entered, a beep is emitted and the LCD displays the letters rA. Pressing the
START/PAUSE button scrolls through the options and allows changes as
follows:-
Rinse Aid Setup (rA).
Water Supply Hardness Setup (hd). (Water softener models only)
Auto Power Option (AP).
End of Cycle Beeps (EC).
Closed Drawer Option (Ld).
Clean/Dirty Dish Symbol (dS).
Integrated and flat door models:- On an integrated or flat door
DishDrawer™ where there is no display, the option chosen is indicated by the
lights showing on the integrated badge as follows:-
Rinse Aid Setup (red light above START/PAUSE button).
Water Supply Hardness (green light above START/PAUSE button).
Auto Power Option (orange light above START/PAUSE button).
End of Cycle Beeps (green light above START/PAUSE button and ECO light
is red).
Closed Drawer Option (red light above START/PAUSE and ECO light is red).
Clean/Dirty Dish Symbol (not available on Integrated or flat door models).
Dry Enhancement Option (no light above buttons, ECO light is red).
Press POWER at any time to exit this setup mode.
2.1.1 Rinse Aid Setup (rA)
The current rinse aid setting is shown using the red LED’s on the touch switch
panel.
The amount of rinse aid dispensed into a rinse cycle can be varied to suit the
level of hardness of the local water supply. It is adjusted for 1 - 5 dispensing
levels.
(1 = approx 0.5mls (1/10) teaspoon of rinse aid, 5 = approx. 2.5mls (1½)
teaspoon of rinse aid).

Press KEYLOCK to advance the rinse aid setting. Once the desired setting is
achieved, press POWER to exit. The rinse aid index is stored in EE memory,
so even with the power removed, the rinse aid level is retained.
2.1.2 Water Supply Hardness Setup (hd) (Where Fitted)
The current supply hardness setting is shown using the red LED’s on the
touch switch panel. One of 5 settings should be selected according to the
known hardness of the supply water. Each setting is appropriate for the
following water supply hardness:
No LED Water Softener turned off, continuous bypass of softener.
1 LED 150-250 ppm water supply hardness.
2 LEDs 250-350 ppm water supply hardness.
3 LEDs 350-450 ppm water supply hardness.
4 LEDs 450-550 ppm water supply hardness.
5 LEDs 550-625 ppm water supply hardness.
Press KEYLOCK to advance the Water Softener setting. Once the desired
setting has been achieved, press POWER to exit.
Selection of a setting affects how the Electronic Controller diverts supply
water, how much water is treated, and how much salt is used in regeneration,
in a manner that optimises the performance of the Water Softener.
2.1.3 Auto Power Option (AP)
The automatic power up sequence that occurs when the tub is opened can be
turned on or off using the KEYLOCK button. If the scrubbing brush symbol is
showing on the LCD, then the auto power up sequence will occur when the
tub is opened. If the scrubbing brush symbol is not showing, then the
DishDrawer™ will not automatically power up when the tub is opened (the
customer will need to press the power button each time they wish to use the
DishDrawer™). Press POWER to exit when the desired setting has been
selected.
2.1.4 End of Cycle Beeps (EC)
The six beeps that occur at the end of the cycle can be turned on or off using
the KEYLOCK button. If the scrubbing brush symbol is showing on the LCD,
then the end of cycle beeps are activated. If the scrubbing brush symbol is
not showing, then the end of cycle beeps are deactivated. Press POWER to
exit when the desired setting has been selected.

2.1.5 Closed Drawer Option (Ld)
The closed drawer option can be turned on or off using the KEYLOCK button.
If the scrubbing brush symbol is showing on the LCD, then the closed drawer
option is selected and it will keep the DishDrawer™ locked at all times by
bringing the lid down. When this mode is selected, the customer needs to
press the POWER button to lift the lid whenever they want to open the
drawer. When they close the drawer again, the lid comes down automatically
after 30 seconds and locks the tub. If the scrubbing brush symbol is not
showing, then the closed drawer option is deactivated. Press POWER to exit
when the desired setting has been selected.
2.1.6 Clean/Dirty Dish Symbol (dS)
(Not available on integrated or flat door models)
The clean/dirty dish symbol can be turned on or off using the KEYLOCK
button. If the scrubbing brush symbol is showing on the LCD, then the
clean/dirty dish option is selected. This means that the end of cycle clean
dishes symbol will remain in the LCD display until the power button is pressed
to clear it. If the scrubbing brush symbol is not showing, then the clean/dirty
dish symbol will disappear when the drawer is first opened at the end of a
cycle (factory setting). Press POWER to exit when the desired setting has
been selected.

3 DIAGNOSTICS
3.1 DishDrawer™ Diagnostics
Dishwasher Diagnostics can only be entered in Power Off mode, i.e. when
there is no display on the LCD or the badge LED’s are off. Diagnostics is
entered by holding the KEYLOCK and START/PAUSE buttons
simultaneously for 5 seconds. Ensure that KEYLOCK is pressed first.
There are currently four levels of diagnostics. To move to the next level,
press POWER. To enter a level, press START/PAUSE. Once a level has
been entered, pressing POWER will exit diagnostics completely. If no level is
entered, then the display will cycle through the four levels and exit after the
last. On entering diagnostic mode, the first level is the Display/Download
Mode.
3.2 Display/Download Mode
In this mode, all LED’s and LCD segments (except keylock) are illuminated.
3.3 Optical LED Download/Fault Display
An optical data download is available here to download all EE data to a PC or
Palm PC via the lower tub-home sensor light pipe. Hold the reader pen over
the lower tub-home sensor light pipe and press START/PAUSE to initiate the
download. A short beep indicates the start and finish of download.
The last two faults are displayed on the LCD (secondary control panel LEDs
for integrated and flat door models) during the optical download. The Current
Fault code is displayed first followed by the Previous Fault Code. To read the
Fault Code on the secondary display, refer to Section 4.7 on Fault Codes.
3.4 Clearing Fault Logs
To clear the current fault code, press the KEYLOCK button until a beep is
sounded. This action moves the current fault into the previous fault while
clearing the current fault. To clear the previous fault code, press KEYLOCK
once more until the beep is sounded.
Warning: Once a fault code has been cleared, it is permanently removed
from memory and cannot be recovered.
Press POWER to advance to the next level.

3.5 Hardware Output Diagnostic Test Mode
This level tests all the hardware outputs and inputs. The LCD display shows
“HO”.
Press POWER to skip hardware diagnostics and advance to the next level.
Press START/PAUSE to enter hardware diagnostics.
Once hardware diagnostics has been entered, the current hardware output
being tested is indicated by letters in the LCD display, and for integrated and
flat door models the LEDs on the touch switch panel using binary encoding,
as shown in the table on the next page.
Different combinations of outputs can be switched on or off together, but the
controller will prevent higher current drawing components such as the wash
pump and the lid motors being turned on together.
Press START/PAUSE to advance to the next hardware output.
Press KEYLOCK to turn the currently displayed output on or off. If the
scrubbing brush symbol (green LED above start/pause button on integrated
and flat door models) is displayed, then that output has been switched on,
and if it is not displayed then that output is off.
Press POWER to exit at any time (all outputs will be switched off on exit).

WARNING: In diagnostic mode there is no component protection. Therefore
take care when running individual components not to overload them. It is
advisable to avoid turning the element on without placing some water in the
tub first.
NB : No fault codes will come up while in diagnostics mode.
Tub Home Sensor Test: At any time during HO test mode, the Keylock
symbol on the LCD display (Keylock LED on integrated badge) indicates the
tub position. On = Closed, Off = Open.
