Depending upon where it is wet, and if any connectors attached to the DDE are wet or corroded, I would first take it inside, clean it thoroughly, drain any water that may be inside, and use LOW heat such as from a heat gun or hair dryer, or simply place under an incandescent table lamp in a warm room for a day or two, and then reinstall (after cleaning the E-box and remedying any water ingress) and "try, try again." That's a LOT less hassle than swapping or reprogramming all the stuff previously described, costs a LOT less, and MAY even work if you're lucky.

BTW, clean all the connector pins & sockets with Electronic Contact Cleaner, and make sure the E-Box is clean & leak-free, WHATEVER you ulimately install.
