Dry it well. Then it *should* be fine. You might put the cm with a desiccant, like microwaved rice or those little moisture boxes that come in pill bottles. Leave it for a day or so to soak up any remaining moisture. The lights/controls of the cm actually run at a low wattage; a malfunction there should not be dangerous unless something causes the heating elements to come on. They are built to be okay if they're on with no water/dry pot, so as long as the cm is away from anything flammable--standard procedure for a cm anyway--it shod be fine even if it turns itself on. Another option, and the one I recommend, is to go buy a new cm. You should not have to worry about the antics of your small appliances. A new cm will be cheap--and safe--and would set your mind at ease.
