At the end of a dry cycle, the display can show Cd. This is NOT an error but is showing the unit is in the cooling cycle.
This can last for up to 60 minutes after the cycle finishes. You do not have to wait for the end of this time and can simply open the door to terminate the Programme and the items removed.
If you require further information please contact LG Customer care on 1300 LG CARE (1300 54 2273) in Australia and 0800 LG CARE (0800 54 2273) in New Zealand to arrange an Approved Service Centre to attend and repair the dishwasher.
