It is common for electric wine openers to have this problem. There are several solutions. You can activate the reset function on some models by simply inserting a pointed instrument such as a pen, paperclip or pencil. You can use small knives, a screwdriver or long tweezers to reset it if the feature isn't available. Place it into the hole, press the button to reverse it. You can also open the device and remove the pin manually if it doesn't seem to work.
