- Model Number
I have a 2 year old Samsung dishwasher model DMR78AHS. A 4E code appeared indicting a water problem. A repair tech replaced the water valve and new hoses. There is plenty of water pressure and the water valve is open and the hoses are not kinked. Still get the error code. I saw a suggestion that the insulation in the door could corrode the wires, took the door off and everything looked fine. Looking for any suggestions as to what to do next.
