Operation
Conditions Monitored by the Computer
l 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.
l Power – If power is interrupted long enough for
the computer to go off, after the power is
restored, the display briefly flashes “Hold” to
indicate the interruption. The door unlock will
be disabled to keep the door from being opened
while the basket is still turning.
l Balance – The computer monitors the balance
signal provided by the AC drive during drain
steps. It will attempt to distribute the load seven
(7) times. The dot at the top of the leftmost
display digit will light following the final
unsuccessful attempt.
l 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.
l 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.
l 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.
The following table, entitled “Display Indications,”
lists the various displays and what they mean. The
operator should become familiar with these
computer displays.
