2 OPTION ADJUSTMENT

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).

599464 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.

599464

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

In this mode, all LED’s and LCD segments (except keylock) are illuminated.

3.3

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

3.4

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

3.5

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.

Hardware Output Diagnostic Test Mode

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).

599464 As mentioned on the previous page, the LCD display and touch switch panel

LEDs are illuminated to correspond to a particular hardware device. The following table details the display order of the test.

Fast Test Cycle

Continuous Cycle Test Mode

In this level the DishDrawer™ can be run continuously in any wash cycle. Once the cycle has finished, the DishDrawer™ automatically restarts the same wash cycle. Press POWER to skip Continuous Cycle. As this is the last level, doing this will exit diagnostics. Press START/PAUSE to enter Continuous Cycle.

Once selected, the LCD backlight flashes on and off to indicate the DishDrawer™ is in continuous cycle and the cycle starts straight away (for integrated and flat door models the LED above the start/pause button will be orange instead of green to indicate the DishDrawer™ is running in continuous cycle). It will run the last cycle that had been selected prior to going into diagnostics mode.

If it is desired to run a different cycle, exit diagnostics, turn the DishDrawer™ on as normal and select the cycle required. Then turn the DishDrawer™ off again, re-enter diagnostics and restart the Continuous Cycle as above.

Press POWER to Exit at any time.

599464 The test sequence in fast cycle mode performs 33 tests. The number of any

failed test is displayed on the touch switch panel LEDs. The test sequence continues even if a test fails. If there are multiple failures the LEDs will change during the test. 0 = LED off, X = LED on.
