Our washing machine suddenly stopped responding to any of the buttons on the control panel. The lights would come on, but I couldn’t select a cycle or start it. It’s an older model, and the manual was lost years ago during a move. I didn’t want to call a repair service just yet — seemed like something simple. I finally found the exact manual through https://manuals.online , and it described how to perform a factory reset using a hidden button combination. I followed it, and it worked like magic. The washer runs like new again — such a relief.
