Why does my Pentair FLECK 2850 SXT Control Unit softener fail to regenerate automatically?
- M
  Monica RiosAug 20, 2025
  If your Pentair Control Unit softener isn't regenerating automatically, it could be due to several reasons. First, ensure that the controller is connected to a constant power source and restore it if the power was interrupted or switched off. Check the meter cable connections in the power head and on the meter cover; replace the cable if it's faulty or disconnected. Other potential causes include a defective power cord (replace it), a defective motor (change the motor), a defective controller (change the controller), a blocked meter (clean or change it), or bad programming (reprogram correctly).

Why is my Pentair FLECK 2850 SXT using excessive salt?
- D
  David HayesAug 23, 2025
  Excessive salt consumption in your Pentair Control Unit might be due to an improper brine refill setting. Check the salt usage and the brine refill settings. It may also be caused by too much water in the brine tank. Another reason may be bad programming, so ensure you program the unit correctly.

What to do if there is too much water in the brine tank of my Pentair FLECK 2850 SXT Control Unit?
- G
  garrettwendyAug 26, 2025
  If there's too much water in the brine tank of your Pentair Control Unit, it could be due to a plugged drain line flow control (clean it), a plugged injector system (clean the injector and screen, replacing if necessary), or a faulty brine valve (change it). Bad programming can also cause this issue, so ensure correct programming. Other potential causes include the controller not cycling (change the controller), foreign material in the brine valve (replace the brine valve seat and clean the valve), or foreign material in the brine line flow control (clean the brine line flow control).

Why is there salted water in the service line of my Pentair FLECK 2850 SXT?
- E
  Eric BrownAug 28, 2025
  If you find salted water in the service line of your Pentair Control Unit, it could be due to several reasons. The injector and/or filter might be plugged, requiring cleaning or replacement. The power head might not be operating properly, necessitating a change. Check for foreign material in the brine valve (replace the brine valve seat and clean the valve) or in the brine line flow control (clean it). Low water pressure (raise inlet pressure to 1.8 bar minimum) or bad programming (program correctly) could also be the cause.

What causes my Pentair Control Unit softener to fail to draw brine?
- M
  Michelle LoveAug 30, 2025
  If your Pentair Control Unit softener fails to draw brine, several issues could be responsible. A plugged drain line flow control (clean it), a plugged injector and/or filter (clean or replace them), or low water pressure (raise inlet pressure to 1.8 bar minimum) could be the cause. Other potential issues include an internal valve leak (change seals, spacers, and/or piston assembly), bad programming (program correctly), or a power head not operating properly (change power head).

How to fix a water pressure drop in my Pentair Control Unit?
- J
  Jeff AlvarezSep 2, 2025
  A drop in water pressure in your Pentair Control Unit could be due to iron deposits in the valve inlet (clean the inlet) or in the valve itself (clean the valve and resin). Additionally, the valve inlet might be obstructed by foreign elements (remove the piston and clean the valve).

What to do if the drain flows continuously in my Pentair Control Unit?
- M
  Melissa HernandezSep 4, 2025
  If the drain flows continuously in your Pentair Control Unit, it could be due to foreign elements in the valve (clean the valve and check it in different regeneration positions), an internal valve leak (change seals & spacers and/or piston assembly), a defective or blocked motor (change motor and check gear teeth), or the power head not operating properly (change power head).

Why is my Pentair FLECK 2850 SXT experiencing resin loss through the drain line?
- R
  Renee SanchezSep 7, 2025
  Resin loss through the drain line in your Pentair Control Unit can occur if the top distributor is missing or broken (add or replace the top distributor). It may also be caused by air in the water system (ensure the presence of an air check system in the brine tank) or an improperly sized drain line flow control (size the drain line flow control correctly).

Why does my Pentair Control Unit controller cycle continuously?
- A
  Alicia LyonsSep 9, 2025
  Continuous cycling of the controller in your Pentair Control Unit might be caused by a power head not operating properly (change power head), a faulty microswitch or wiring loom (change microswitch or wiring loom), or a defective or badly set cycle cam (reposition or change cycle cam).
