Why is my Pentair Control Unit backwashing or purging at an excessively low or high rate?
If your Pentair Control Unit is backwashing or purging at an excessively low or high rate, it might be due to an incorrect drain control being used. Replace it with the correct size controller. Another cause could be foreign matter affecting valve operation; remove the drain control and clean the ball and seat.
What to do if my Pentair 760 controller has no water flow display when water is flowing?
If your Pentair 760 controller shows no water flow when water is flowing, first check if the bypass valve is in the bypass position and shift it to the non-bypass position. Also, the meter probe might be disconnected or not fully connected to the meter housing; fully insert the probe into the meter housing. Finally, restricted meter turbine rotation due to foreign matter in the meter could be the issue; remove the meter housing, free up the turbine, and flush with clean water. The turbine should spin freely; if not, replace the meter.
What causes my Pentair Control Unit to run out of conditioned water between regenerations?
Running out of conditioned water between regenerations with your Pentair Control Unit can stem from several issues. Improper regeneration could be the cause, so control the brine dosage set and repeat regeneration. An incorrect brine setting could also be responsible; set P6 to the proper level. Additionally, incorrect hardness or capacity settings might be the problem; set to correct values. Increased water hardness could also lead to this issue; set the hardness to the new value. Lastly, restricted meter turbine rotation due to foreign matter in the meter could be the cause; remove the meter housing, free up the turbine, and flush with clean water. The turbine should spin freely; if not, replace the meter.
What does ERR 3 mean on my Pentair Control Unit?
If your Pentair Control Unit displays ERR 3, it indicates that the controller lost the position of the camshaft, which should be rotating to find the Home position. Wait for 2 minutes; the controller should return to the Home position, with an hourglass icon flashing to indicate that the motor is running. If the camshaft does not rotate, check the motor connections, if the motor wire harness is connected to the motor and the controller, the optical sensor connection and position, and if the motor and camshaft gears are engaged. If the camshaft rotates for more than 5 minutes to find the Home position, check the optical sensor connection and position, the camshaft connection, and the cleanness of the camshaft slots.
What does ERR 2 mean on my Pentair Control Unit?
If your Pentair Control Unit displays ERR 2, it means the controller power does not match 50 or 60 Hz. Disconnect and reconnect the power. If the problem persists, obtain an appropriate controller or AC transformer.
