How to reset Pentair Controller when ERR 1 is displayed?
ERR 1 is displayed when the controller power has been connected and the control is unsure of the state of operation. Press the UP arrow and the control should reset.
What to do if my Pentair Logix 740 Controller brine tank overflowed?
A brine tank overflow can be caused by an uncontrolled brine refill flow rate, an air leak in the brine line to the air check, or a drain control clogged with resin or other debris. To address this, first remove the brine control to clean the ball and seat. Then, check all connections in the brine line for leaks, referring to the instructions. Finally, clean the drain control to remove any blockages.
Why won't my Pentair Controller draw brine?
If the control is not drawing brine, it could be due to low water pressure or a restricted drain line. Other potential causes include a plugged or defective injector, valve discs not closed, or the air check valve closing prematurely. You can make the correct setting according to the instructions to fix low water pressure and remove any restriction in the drain line. Also, clean the injector and screen. If needed, remove foreign matter from the disc and check disc for closing by pushing in on stem. If the air check valve is closing prematurely, put the control momentarily into brine refill, C8.
What should I do if my Pentair Logix 740 valve won't draw brine?
If the valve won't draw brine, it may be caused by low water pressure, a restricted drain line, a plugged or defective injector, or the air check valve closing prematurely. To fix this, set the pump to maintain 20 psi at the softener and change the drain to remove any restriction. Also, clean the injector and screen. For the air check valve, put the control momentarily into brine/slow rinse, C2.
What causes no water flow display when water is flowing on a Pentair 760 controller?
If there is no water flow display when water is flowing on a 760 controller, it could be due to the bypass valve being in bypass, the meter probe being disconnected or not fully connected to the meter housing, or restricted meter turbine rotation due to foreign material in the meter. Shift the bypass valve to the not-in-bypass position and fully insert the probe into the meter housing. Remove the meter housing, free up the turbine, and flush it with clean water.
How do I fix my Pentair Controller that regenerates at the wrong time of day?
If the control regenerates at the wrong time of day, it is likely that the controller is set incorrectly. Correct the time setting according to the instructions.
Why is there no conditioned water after Pentair Logix 740 regeneration?
The absence of conditioned water after regeneration can be due to no regenerant in the regenerant tank, a plugged injector, or the air check valve closing prematurely. To resolve this, add regenerant to the regenerant tank and clean the injector and screen. If the air check valve is closing prematurely, put the control momentarily into brine/slow rinse, C2.
Why is my Pentair Logix 740 system using more or less salt than the regenerant setting?
If the system is using more or less salt than the regenerant setting, it could be due to foreign matter in the valve causing incorrect flow rates. Remove the brine control and flush out the foreign matter. Advance the control to brine/slow rinse, C2, to clean the valve, and then position the control to "fast rinse, C7” to remove regenerant from the tank.
What to do if Pentair Logix 740 Controller will not regenerate automatically?
If the control will not regenerate automatically, it may be because the AC adapter or motor is not connected, or the motor is defective. Connect the power and if that doesn't work, then the motor is defective.
What to do if ERR 3 is displayed on my Pentair Logix 740?
If ERR 3 is displayed, it means the controller doesn't know the position of the camshaft, which should be rotating to find the Home position. Wait for two minutes for the controller to return to the Home position; the hourglass should be flashing on the display, indicating the motor is running. If the camshaft is not turning, check that the motor is connected and that the motor wire harness is connected to the motor and controller module. Also, verify that the optical sensor is connected and in place and that the motor gear has engaged the cam gear. If the camshaft is turning for more than five minutes, verify that the optical sensor is in place and connected to the wire, that the camshaft is connected appropriately, and that no dirt or rubbish is clogging any of the cam slots.
