You should set sourceComponent = undefined or source = "". Usually, I use this code:

Loader{
    id: loader
    function show(component) {
        sourceComponent = component;
    }
    function hide(){
        sourceComponent = undefined;
    }
}

You can just set the active property to false for unload or true (default) for loading.

You didn't say what the actual issue was, but in case you ran into errors where the component you're trying to unload is trying to access things it shouldn't, it could be because Loader deletes the item using deleteLater(), which means it doesn't get deleted instantly. See this bug report for more info:
