Water over flows think its the water sensor

It's likely just the hose to the pressure (water level) switch that has come loose or fallen off. Remove the console screws and flip back the console to get access to the pressure switch and the connections. If the connection end of the pressure switch hose looks "stretched", trim 1/4" off and re-seat it.
If the hose looks ok (no cracks or splits), check the other end of the hose which connects to the side of the tub.
The see if the pressure switch is faulty, remove the pressure switch hose and attach a small hose to the pressure switch. Blow into it gently and listen for "clicking". Test with a fill to see if the switch shuts off the water valve.

Let me know if you need more assistance. If so, please post your model number.
Good luck!

Remove the back of the control panel and look for the clear hose that runs to your water level switch. Either blow or use a small blast of compressed air down in it. That should clear a clog in the cup at the bottom of your tub and retry. if no luck than replace the water level pressure switch. Powder detergents like to clog this hose.
