The flood detector (it is not a switch) is on the left side of a pan under the bottom drawer. Shut off power to the DW and Remove botton drawer and you will see a circuit board on the left side with "contacts" that stick down into the water. Mop out the water and un plug this board (called power control module I believe) clean it off and dry it out. Put back together. Best of luck.
