You should get a message that says LOW AMPS/CELL?.
At that point, if you verify that your salt level is at least 3000 ppm, the cell is clean, and water temperature is at least 75 degrees, THEN run a TEST POOL PILOT to see where the Cell Amps and Volts are. The normal operating range is 24- 28 volts, and the amperage depending on the Cell Power setting; Cell Power 1 = 5.0 amps, Cell Power 2 = 6.5 amps, Cell Power 3 = 8.0 amps.

Perform a visual inspection of the two outer blades too. These will wear in relation to the cell life by getting eroded on the leading edges of the blades.
