If there is CD on the display, the washer is in the cool-down mode. Indeed, the message appears every time the washer finishes a cycle, and the system begins to cool down as it should. In this mode, the machine will continue to turn over the load from time to time within up to 4 hours. This function can prevent wrinkles and make the items look fluffier. The code will disappear when it is 4 hours since the mode was activated, or you push any button to remove the items.
