Hi, I am a new owner of a 1998 Newell. I am not familiar with Aquahot systems. When I put the aquahot in the diesel position, I hear it start the red light comes on, but after 15 minutes or so the light goes out. If I don't do anything else the temp will gradually go down and last night i noticed it had decreased to 138. I turned on the electric switch and it works just fine and stays within the parameters it is supposed to. Thanks for your help
