Hardware Output Diagnostic Test Mode - Fisher & Paykel DishDrawer DD605 Service Manual

5.1.4 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, letters in the LCD display indicate the current hardware output being
tested. For integrated models, the LEDs on the touch switch panel indicate the hardware output being tested, using
binary encoding, as shown in the table below.
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 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).
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.
