摘要： A freeze protection method for a washing machine includes:
determining, by a control unit, whether or not laundry items exist after a washing process, when a freeze protection course is selected;
determining, by the control unit, whether a freeze protection operation condition is satisfied or not, when no laundry items exist;
and operating, by the control unit, a water supply device to supply water and operating a drain device to discharge water, when the freeze protection operation condition is satisfied; and returning to the determining of whether the freeze protection operation condition is satisfied or not, when a preset standby time passes after the water supply device and the drain device are operated.
