You are exactly right about the unit going into an overflow condition. The drain pump will continuously run to prevent the dishwasher from flooding your house if there is really a leak. What that means is that water has worked its way down into the base pan below the dishwasher tub causing the unit to do nothing but drain. This is normally caused by the drain being clogged or too many suds in the tub causing the tub to overflow a bit. Either way, you'll need to uninstall the dishwasher and tip it forward at a 45-degree angle to drain the water out of the base pan. Be sure to put a towel under the dishwasher first so that the water is soaked up in the towel instead of going all over the floor. Once you've drained all the water out of the base pan, reinstall the dishwasher and pour a gallon of water in the dishwasher. If it drains it out right away and doesn't wash or refill, you still have water left in the base pan to try again, otherwise you're good to go.Now if you don't want to do all this work just to get your dishwasher working again and you have time, let the dishwasher just sit unused for a week and the water in the base pan will evaporate as time goes on and the dishwasher will start working again after a week.

No problem. If for some reason you fix the issue and the problem were to come back, then you may need someone to come out and see where it's leaking from because it wasn't just a fluke from suds or a drain on your sink being partially clogged, you actually have a leak below the dishwasher going into the base pan.
