After researching the error code I forum the part at appliancepros.com and ordered the part and the o-ring that was recommended. The repair was pretty straight forward I removed the dishwasher form the cabinet and then removed the right side panel. I located the defective sensor and replaced it after I vacuumed out the dishwasher tub that was full of water. Upon removing the sensor there was still some water in the lower casing of the dishwasher that could not be vacuumed out. After replacing the sensor I powered the dishwasher on and the first error code cleared but a second appeared. As it turns out the dishwasher has a anti flood feature in the event of a water leak it shuts down and the pump comes on to prevent the unit from flooding your kitchen. I had to turn the unit on its side and remove the water sensor and dry it off. All is fine now.
