When turning on aqua rite t-15 control box the power light and generating light come on. After 1-2 minutes the generating light goes off and the check salt and check cell lights come on. The cell is clean. The salt checks at 3300 using test kit but system shows 1500. Bad cell or something in board?
Hello Strout7 - It sounds like a bad cell. The average lifespan is 3-5 years. You can rule out the board by checking the amperage in both polarities.
To do this press the diagnostics button 3 times. This should bring up the amperage. Write that number down. To switch the polarity, move the main switch from Auto to Off and back to Auto. That will give you the amperage in the second polarity. If either one of those readings is 0, the board needs to be replaced.
If you get an amperage reading on both polarities, it is more than likely a bad cell.
