This indicates there was a power failure. This function protects
the dishwasher in the event the power goes out or the power to
the unit is disrupted. When power is returned, and a button is
pushed, this will display for 10 seconds and then go away.
"Cd" means Cool-Dry. This is an additional drying cycle to assist
drying performance in the 'Quick' course. This cycle runs for a
further 30 minutes after the course has finished. It can be
interrupted at any time by opening the door.
"CL" means Child-Lock. This function is used to lock or unlock
the control buttons to prevent all the setting from being changed
by a child. It can only be activated during the wash cycle.
When the unit is displaying "F", the sensor is measuring the
water clarity. After 5 minutes of sensing (except draining and
filling), the unit's display will then show the processing time.
This is not an error code, but indicates the setting of the delay
start. To cancel the function, turn the power off. To change the
course and option, open the door and select another course and
option. Countdown will then continue after door is closed again.
