Operation
Wash Program Execution
If the power fails during execution of a
program, and is of less than one second, it
is ignored. If the failure is longer than one
second, the machine stops. Upon
restoration of mains power, the display
shows CYCLE CONTINUE? and the power
failure indicator illuminates on the front
panel. If you wish to restart the program at
the point in which power failed, press the
START key. At this point, the program
restarts at the point of power failure and the
power failure indicator turns off. If you wish
to cancel the program, simply press the
RESET key. This function is not active
while a single cycle is running.
End of Program
When a program has completed, the
message PLEASE WAIT is displayed and
the buzzer sounds for 40 seconds. The
buzzer can be silenced by pressing the
RESET key. If the temperature or water
level are out of bounds, the display shows
the offending value and the door cannot be
opened.
Malfunction Alarms
The state of the water temperature and
water levels are constantly monitored to
prevent functioning problems with these
devices. Watch Dog Timers (WDT) are
used to prevent cycle failure when
temperatures, fills, drains, and levels don’t
meet programmed values. In the event of a
program fault, the buzzer sounds and the
display changes to show the fault:
LEVEL FAULT
Indicates a problem with the level sensing
system. This could be a loose or cracked
water level tube, the level sensor, or the
level sensing circuit. As long as the system
detects a problem with the level sensing
system, the machine will be inoperable.
The buzzer can be disabled with the RESET
TEMP FAULT
Indicates a problem with the temperature
sensing circuitry, temperature probe, or
wiring. The machine continues to function,
although auxiliary heating (if equipped) is
not possible. The Temperature fault
indicator on the control panel will be
illuminated.
Indicates the programmed temperature was
not reached within the allotted time. The
most common cause is a malfunctioning
auxiliary heating system. A short WDT time
and very cold water can also cause this
problem. Pressing the START key will
cancel the alarm.
Indicates the programmed level was not
reached within the allotted time. The most
common causes:
During Fill
>
Faulty water inlet valve
> Low or no water pressure
> Faulty drain valve
> Problem with water level tube
Pressing START will continue the program,
