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.
