Operation

Conditions Monitored by the Computer

●Door – The computer continuously monitors the open/locked status of the door. If it detects that the door is open during a wash cycle, it immediately aborts the cycle and executes the stop routine.

●Power – If power is interrupted long enough for the computer to go off, after the power is restored, the display flashes “Hold” briefly to indicate the interruption. The door unlock will be disabled to keep the door from being opened while the basket is still turning.

●Balance – If the AC inverter balance detection system is utilized, the computer monitors the balance signal provided by the AC drive during drain steps. The computer will attempt to distribute the load seven times. The dot at the top of the leftmost display digit will light following the final unsuccessful attempt. If the inverter balance detection is not utilized, this dot will not light.

●Water level – The computer attempts to maintain the water level programmed for the fill preceding the agitation step. If the level falls below the programmed level, the computer will stop the time countdown and re-energize the fill valves until the level is restored.

●Water level in a heat step – In order for the computer to energize the heat output, there must be at least a low water level in the machine. If this minimum level is not detected, the heat output will be turned off until the required level is restored.

●Temperature probe problem – If the temperature sensor fails when prompted for degrees Fahrenheit, the computer flashes “tSFL” in Program Mode rather than showing the temperature. If the temperature sensor fails when prompted for degrees Celsius, the display will read “-17C” rather than showing the temperature.
