The proper function of a water softener is to help filter out these contaminants and make your water more palatable and usable. If you already have one installed and it starts to go out, water softener troubleshooting may be in order.

What Is a Water Softener?

Water softener systems are appliances that run silently in the background to remove minerals from your water. They're useful if you have well water, which tends to have higher levels of minerals from ground run-off. They can work properly for years without an issue, but over time, hard water symptoms may return.

Some of the benefits of a water softener include:

Preventing premature plumbing issues
Improving the effectiveness of cleaning supplies
Safeguarding against appliance mineral buildup
Removing grime on dishes
Making clothes softer and brighter
Reducing environmental impact
Improving your skin and hair

Troubleshoot Your Water Softener

Recognizing the warning signs can help you diagnose common water softener problems. It can also help you get your soft water back before your appliances and home are covered in scale buildup and soap scum. The following are signs it's time for water softener troubleshooting.

Return of Hard Water Symptoms

The Symptom: Returning hard water symptoms is the most obvious sign of a failing water softener. You may start to notice some of the same problems you had before installing the device, such as scale buildup on your faucet or showerhead, soap scum on shower doors and dry skin.

What It Means: If hard water is back, your system isn’t doing its job. This could be due to several common issues. The softener may not be able to complete the regeneration process, which is needed to remove hard minerals. The resin beads inside the tank may be old and no longer trap large mineral pieces. It can also be as simple as an unplugged unit or the bypass valve in the wrong position. If the valve sticks in the wrong position, it can prevent water from flowing through the softener.

Sudden Drop in Water Pressure

The Symptom: If your water flow used to be strong but is now much weaker, it could be because of your water softener.

What It Means: A clogged water softener restricts water from flowing through. Over time, with normal water usage, sediments build up inside the system and the resin beads become impacted. In severe cases, resin beads can become damaged, which causes the beads to block the outlet pipe. If you switch to the bypass valve and your water pressure returns, your softener is the culprit.

The Salt Level Never Seems to Change

The Symptom: Saltwater softeners use salt to flush away minerals in the water. Eventually, the salt dissolves and you’ll have to add more. If you notice the salt level remains unchanged despite regular water use, your softener may be bad.

What It Means: This is usually caused by a salt bridging issue. A salt bridge is a hard layer of crystallized salt on the brine tank. There's no salt below the bridge, and the crust prevents salt above the bridge from dissolving, which halts the regeneration process.

Your Brine Tank Has Too Much Water

The Symptom: If you see excess water in the salt tank, it could cause trouble for your water softener.

What It Means: A water softener only has a few inches of water in the brine tank. If the water levels are too high. It’s a sign the system can’t remove the brine during regeneration due to a clogged line or damaged float valve.

You Find Floating Beads In Your Water

The Symptom: If you notice tiny, amber-colored beads in your toilet tank, it could indicate your softener is going bad.

What It Means: When this happens, the resin tank has ruptured and needs replacing.
