4.2.6 Exiting the Fault Indication mode:
To exit the fault indication mode, and clear any saved fault
codes from memory, press and hold down the START/
CANCEL button for 3 seconds. The control will then go into a
stand-by (off) state with all LEDs off.
Note: The Average
Clean Water Turbidity (ACWT) value will also be cleared.
To exit the fault indication mode, without clearing the saved
fault codes: Remove power; or carry out the following se-
quence:
1.
Align the WASH CYCLES and HEAT OPTIONS knobs
so that both knobs are horizontal with their position indicators
pointing away from each other;
2.
Press and hold the Start/Cancel button for 3 seconds.

4.2.3 Identifying any faults that may have occurred:
If a fault has been detected by the Field Test Cycle, or by the
Factory Test Cycle, and hence the Fault Indication mode has
been automatically activated, then the WASH CYCLES and
HEAT OPTIONS LEDs will alternate on and off once every
second, to indicate that a fault has occurred. This will
continue until the first fault is found, (the LEDs will then
behave in the manner specified below, and the Factory/Field
test fault indication buzzer will be silenced if it was still
activated).
To check if a particular fault has been recorded, rotate the
appropriate control knob to the corresponding Fault type to
be checked for. (Refer table below). If the selected fault type
has occurred, then the indicator LED above that knob will
flash, (at a rate of 0.5 second on, 0.5 second off), otherwise
the indicator LED will be off.
Note: As the two knobs operate independently of each
other, two faults can be identified at the same time.
