DIAGNOSTICS

6.1 Overview – LCD Models
If a fault occurs that prevents correct operation
of the dryer, and is detected by the controllers,
the dryer is stopped, the LCD shows a fault
code and the beeper is continuously turned on
and off.
Pressing any button once will disable the
beeping. The fault code information will remain
on the LCD screen until the power supply to the
dryer is turned off.
If the Dryer has been either turned off or isolated from the power supply, the fault code can be
recalled from memory by entering diagnostic mode. (Refer to Section 7.1).
If START/PAUSE is pressed while the fault code is displayed, the beeping will stop and the optical
download is activated. (Refer to Section 7.4).
User Warnings
In the case of User Warnings, the LCD screen will display the User Warning and the beep tone will
change from a continuous tone to a musical series of beeps, which are repeated every 5 seconds.
Depending on the nature of the User Warning, the operation of the dryer may cease or continue to
'limp on' until the cycle finishes or the user intervenes.
Pressing the POWER button when a User Warning is displayed will immediately turn the dryer off.
User Warnings are saved to memory as Fault Codes, and the last Fault Code will be permanently
stored.
The warning will also be recorded in the Warning Status screen (refer to Section 7.2.3), however
the information on this screen will only be stored for as long as power is supplied to the dryer.
When the dryer is isolated from the supply, the information in this screen will be erased.
