Amanda,
Please help us help you. I assume that we’re talking about a dishwasher (float switch); so the logical conculsion is that the undertray is flooded and needs draining, then the leak must be found.
If you would put up your model number and even better the serial number (Its on a label around the door) we can be a bit more specific.

You don’t mince your words do you Amanda 🙂
If your machine is getting these 2 error codes, they are most likely associated with a soap/limescale build-up in the pressure switch hose attached to and part of the sump hose. 😉
