I have returned 2 timers in one week. One was just a brick and the other would not turn off when the program time ended. My new timer is having the same issue turning off after the programmed time ends. I tried turning it off manually and running a test. After 30 minutes of resetting the timer, using bluetooth and removing the batteries it finally stopped. I would appreciate any help solving this issue. We are on a well, so if this timer does not turn off it will ultimately drain the tank leading to no water in the house. Thanks.
