Common Water Softener Problems and How to Troubleshoot Them?

• The common water softener problems are not softening water, low water level, non-regeneration, high water level, brown water in tank, leaking, discolored water, over salty water, and continuous draining.
• The solutions are to inspect the injector, remove slat mushing, contact the plumber, readjust water softener settings, and tighten the connection.

Water softeners are complex systems designed to eliminate the problems of using hard water in your home. Like any other machinery, water softeners can have issues, and a faulty water softener may even reduce your water quality.

Seeking some technical assistance from certified water softener companies can be expensive. And troubleshooting the problems to make the water softener systems function correctly can be challenging.

However, we have gathered a list of the most common water softener problems and ways to troubleshoot them.

Most Common Water Softener Problems and their Causes

Problem	Cause of the problem
Hard water	The softener must be completely broken. The system is producing an insufficient amount of soft water.
Low water level or no water in the brine	Crooked or broken brine tank float switch. Clogged brine valve/line Brine tank float switch
The system does not regenerate properly	Misconfigured timer Broken timer Restricted drain control Clogged injector Salt bridging Salt mushing Not enough water in the brine tank Too much water in the brine tank Dirty/worn-out resin bed Motor failure
The brine tank water level is too high	Crooked or broken brine tank float switch Accumulation of dirt Clogged brine valve/line House water pressure too low or high The brine valve assembly has misplaced/missing/ worn-out O-ring Salt mushing Plugged control valve Restricted drain control Misconfigured timer Clogged injector Brine tank float switch
Brown water in the brine tank	Rust in water Dirt in salt
Leaking	Installation error Misplaced/damaged tank, valve, hose, O-ring
Soft water is discolored.	Fouled resin bed Rust in water Dirt in salt
Increased salt use	Too much water in the brine tank Improper system settings
Slippery and overly salty water	Restricted drain control The system uses too much salt.
The water softener makes loud noises.	Does not indicate any problem
Resin beads in the water system	Cracked riser tube basket Worn out resin bed
System drains continuously	Brine tank float switch stuck. Restricted drain control Clogged injector Wrong settings controlling cycle length or broken circuit switch House water pressure too high or too low Clogged brine valve/line
Low water pressure	The system sized too small. Resin beads have clogged fixtures. Plugged control valve Worn out or clogged resin bed
The system does not use salt.	Salt bridge

Water Softener Problems and Troubleshooting Guide

You may need help from a professional to solve complicated problems, but some common water softener issues are easy to fix.

1. Blockages or Clogging

The hard water consists of magnesium and calcium that leaves chalky deposits on your pipeline and fixtures. This same residue can also be left behind in your water softening system.

Over time, the minerals and salt pile together, causing the water line that runs through your water softener to clog. It generally occurs in the valve injector and brine line.

Fixing It

Use needle-nose pliers to inspect the injector. Pull it out through the small opening and a needle or safety pin to eliminate the debris if something is lodged in the small hole.

2. Salt Bridges or Salt Mushing

A salt bridge is the development of a hard crust, creating a space between water and salt in the brine tank.

Similarly, salt recrystallizes on the bottom in salt mushing, creating a salty sludge. It can also affect your water softener’s performance.

Fixing It

• Break the salt bridge with any broom handle.
• Remove salt mushing by draining

3. Resin Replacement

The resin is responsible for capturing the minerals to turn hard water into soft water by exchanging ions. As the resins start to degrade, the capacity of your softener is reduced.

Fixing It

For a short period, you can adjust your water softener’s settings. This will allow it to regenerate more often and work more efficiently. For a long-term fix, you need to seek help from a professional.

4. Motor Issues

The motor of your water softener may fail. It can cause severe issues in the system’s performance. The motor won’t be able to move the valve between modes.

Fixing It

Check the warranty and contact a plumbing professional as they can confirm damage, solutions, and costs and replace your motor if necessary.

5. Brine Tank Overflow

A brine line blockage, a clogged injector, a malfunctioning valve, or a stuck float can lead to an overflowing brine tank.

Fixing It

Check if it is properly connected and the caps have a tight fit. Check if there is salt build-up in the brine line float. The brine line valve may be clogged with debris. Check the drain line and injector. Lastly, a professional can clean or replace an injector.

Here are a few steps to keep your system working for a long time.

1. Use pure salt with iron remover.
2. Do not add salt until all the existing salt in the tank is used.
3. Clean the parts responsible for controlling the valve and resin bed once a year with Iron-out.
4. Clean the brine tank once a year.
5. Ensure the water softener’s drain line is not pushed down to a floor drain.
