My stand mixer has outsmarted me

[oyceter]

So apparently, whenever I knead bread in my stand mixer for too long, the motion somehow screws the workbowl in more securely.

In other words, I cannot for the life of me detach the thing.

It's a KitchenAid Artisan. Does anyone have any tips? It's not really urgent, but I'd like to wash it someday...
