What to do if my Pentair FLECK 3150 NXT water softener fails to regenerate?
If your Pentair Control Unit water softener isn't regenerating, it could be due to a few reasons. First, ensure the unit has continuous electrical service by checking the fuse, plug, and switch. If the power was interrupted, reset the time of day. If the timer is defective, consider replacing the controller.
How to reduce excessive salt consumption in my Pentair FLECK 3150 NXT?
To reduce excessive salt consumption in your Pentair Control Unit, check the salt usage and salt setting to ensure it is properly adjusted. Also, examine the brine tank for excessive water; refer to the troubleshooting steps for 'Excessive water in brine tank' for guidance.
Why is my Pentair FLECK 3150 NXT producing hard water?
Your Pentair Control Unit might be producing hard water due to several reasons. The bypass valve could be open, so ensure it is closed. The brine tank may be empty, so add salt, maintaining the level above the water. A plugged injector screen, insufficient water flowing into the brine tank, a leak at the distributor tube, or an internal valve leak could also be responsible. Clean the injector screen, check the brine tank fill time, inspect the distributor tube for cracks, check the o-ring and tube pilot, and replace seals, spacers, and/or the piston if necessary.
Why is there a loss of water pressure in my Pentair FLECK 3150 NXT?
A loss of water pressure in your Pentair Control Unit can occur due to iron buildup in the line to the water softener or within the softener itself. Clean the line and the controller, and add a mineral cleaner to the mineral bed. Increasing the frequency of regeneration may also help. Additionally, the inlet of the softener might be plugged with foreign material; in this case, remove the piston and clean the controller.
What causes excessive water in the brine tank of my Pentair Control Unit, and how do I fix it?
Excessive water in the brine tank of your Pentair Control Unit can be caused by a plugged drain line flow control, a plugged injector system, a controller that is not cycling, foreign material in the brine valve, or foreign material in the brine line flow control. Try the following: * Clean the flow control. * Clean the injector and screen. * Replace the controller. * Replace the brine valve seat and clean the valve. * Clean the brine line flow control.
Why doesn't my Pentair FLECK 3150 NXT softener draw brine, and how can I fix it?
If your Pentair Control Unit softener isn't drawing brine, the drain line flow may be plugged, the injector could be plugged, or the injector screen might be clogged. Clean the drain line flow control, the injector, and the screen. Also, check if the line pressure is too low and increase it to 1.4 bar. Internal valve leaks can also cause this issue, so change the seals, spacers, and piston assembly. Finally, verify that the cam cycled; if not, check the drive motor and micro-switches.
What should I do if my Pentair Control Unit drain flows continuously?
If the drain on your Pentair Control Unit flows continuously, the controller may not be programming correctly, or there might be foreign material in the valve body, or there is an internal valve leak. Check the controller program and the positioning of the controls. If it's not positioning properly, replace the power head assembly. Remove the power head assembly and inspect the bore for foreign material, and check the valve body in various regeneration positions. If there is an internal valve leak, replace the seals and piston assembly.
Why does my Pentair FLECK 3150 NXT Control Unit controller cycle continuously?
If your Pentair Control Unit controller cycles continuously, it may be due to a maladjusted, broken, or shorted micro-switch. Determine if the micro-switch or controller is faulty and replace it, or replace the complete power head.
Why is my Pentair FLECK 3150 NXT losing mineral through the drain line?
Loss of mineral through the drain line in your Pentair Control Unit could be due to air in the water system or an improperly sized drain line flow control. Ensure that the well system has a proper air eliminator control and check for a dry well condition. Also, check for the proper drain rate.
