DIAGNOSTICS

5.1 DishDrawer™ Diagnostics
DishDrawer™ diagnostics can only be entered in Power Off mode, i.e. when there is no display on the LCD, or the badge
LEDs are off. Diagnostics is entered by holding the KEYLOCK and START/PAUSE buttons simultaneously for 5
seconds. Ensure that KEYLOCK is pushed 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 diagnostics mode, the first
level is the display/download mode.

5.1.1 Display / Download Mode

In this mode all LEDs and LCD segments (except keylock) are illuminated.
Note: there is no LCD backlight on DD605 models

5.1.2 Optical LED Download / Fault Display

An infrared 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 PC or Palm PC uses Smartool software, available on CBW, to view the fault log and usage history data.
Also a wash log has been added to the DD605 Smartool. Progress of the current wash program is logged to EE after
each wash command completes. This log is reset when a new wash program starts.

Note: in early production DD605 models, the pen download feature has been disabled because it was causing the
product to go into a nuisance "pause" mode intermittently.
The last two faults are displayed on the LCD (secondary control panel LEDs for integrated 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 for integrated products, refer to Section 6.1 on Fault Codes.

5.1.3 Clearing Fault Logs

To clear the Current Fault 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.
