Ecosense tankless shuts off after 10 minute
Worked fine for our first 18 months in this house. Not sure how old it is. About a month ago, we came back from two weeks vacation and it hasn't worked right since. After ten minutes or so, water turns cold. I observed the unit while running the shower. It turned on fine and heated up. About eight or ten minutes in, it cycled twice, with a clear cycling noise, but stayed on. Another minute or two later, the controller light turns off, the unit stops, and the water turns cold.
