OPERATING INSTRUCTIONS
4-20
Water Level Refresh
While a program is running, if the water level drops to a level which is 3 cm. below the target level,
cold water will automatically be added to replenish the level.
Unbalance
If, during a spin segment, the load is excessively out of balance, the spin will stop, and a
redistribution of the goods will take place. If three consecutive out of balances occur, the machine
will end the program. After the first unbalance, the balance indicator will light on the control panel.
Power Failure
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 “RESTART CYCLE?” 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. Then, if the water level is lower than 3 cm. and the temperature is lower than
40 ºC, the message “END OF ACTIVITIES” is displayed and the door may be opened. 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) is 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:
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
key.
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.
