Hi. This morning, I notice two small, 1/2 green, 1/2 yellow cords sticking out from the bottom of the dishwasher door, in that crack between the door and the base of the dishwasher. The cords run together, coming together in a type of "plug". It looks to me like maybe this should be plugged in somewhere, but has come loose. Do I need to call a dishwasher repair person for this? Is it an electrical danger? Any advice is greatly appreciated.
