LO error code


The "LO" code appears when the washing machine has finished the selected wash cycle, but cannot unlock the door. Verify that the door is closed properly, push the "Off" button, and wait two minutes. The door should unlock and the error code will disappear. If the error code remains, unplug the washing machine, wait two minutes and plug it back into the electrical outlet.
