Troubleshooting Pentair Water Softners

Troubleshooting Pentair Water Softners. Water softeners that are used in a home are designed to treat hard tap water by removing iron and other minerals. This, in turn, will eliminate stains and soap scum from forming on clothes or the fixtures in your bathroom. However, if your water heater is not working correctly, you will need to fix any issues that are present with the unit. This can be done by first examining your Pentair water softener for any broken parts.

Step 1

Open the brine tank and see if the salt is at the correct level. If the salt level is too low the water may not feet or look soft when coming out of the tap. Add more salt to the tank and wait for the softener to enter the regeneration cycle.

Step 2

Observe the control valve and see if it is starting the regeneration cycle. If the regeneration cycle is not starting check and see if the power cord is plugged into an outlet.

Step 3

Open the door to the circuit panel and see if there is a tripped circuit or a blown fuse. Reset the circuit or replace the fuse and see if the water softener begins to regenerate.

Step 4

Reset the time of day on the unit if there is a power outage. This is done by pushing the red button on the left side of the dial. You then need to simultaneously adjust the 24-hour gear wheel until the current time is displayed.

Step 5

Reset the program wheel is the softener appears to be using too much salt. Locate the people dial that is connected to the Program Wheel on the right side of the control box. Rotate the dial to the number of people that are in the house.


  • Always keep an extra bag of salt in case the brine tank gets low and you cannot get to the store to get more salt.
