Odor
This indicates there was a power failure. This function protects
the dishwasher in the event that 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. This cycle runs for a further 60 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 settings 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.
This is not an error. When you open the door right after heating
wash, rinse or dry, buzzing sound would keep on ringing for
safety if the inside is heated.
If the dishwasher is not used daily, we recommend to run a
Quick cycle once or twice a day until you have a full load.
In case odor still persists, run a vinegar rinse through a Auto
cycle by putting 2cup(500ml) of white vinegar in an upright
measuring cup in the lower rack, without detergent.
We recommend to maintain according to the USER
MAINTENANCE INSTRUCTIONS.
