Why is my water softener not softening the water?
Most often the salt has run out or formed a hard bridge, the bypass valve was left in bypass, or the hardness setting is too low for your water. Less often the nozzle and venturi is clogged, the drain hose is kinked, the power was off, or the water has more iron than a softener can handle. Check those in order before calling for service.

Step by step
Read when to stop and call a pro, further down this page, before you start.
Step 1: Test the right tap
Check hardness at a faucet you know is on softened water, not an outside spigot or a cold line the installer left hard.[1]
Step 2: Look at the salt
Lift the salt lid; the tank should be at least one-third full, and if it is empty refill it with pellet, nugget or coarse solar salt.[1]
Step 4: Check the bypass valve
Make sure the bypass valve is in the service position, not bypass, and that any blending valve is closed.[1]
Step 5: Check power and clock
Confirm the softener's plug-in power supply is in a live outlet not controlled by a switch, and reset the clock if it is flashing.[1]
Step 6: Check the hardness setting
Compare the hardness number on the control with your actual water hardness in grains per gallon, adding 5 for each 1 ppm of clear-water iron.[1]
Step 7: Check the drain hose
Follow the drain hose to the drain and clear any kink, blockage or high loop that could stop the softener drawing brine.[1]
Step 8: Run a manual recharge
Start a recharge from the control, then test the water again after it finishes, which on GE's units takes about two hours.[1]
When a softener stops softening, the cause is usually something simple you can check in ten minutes: the salt, the bypass valve or the hardness setting. Only after those are ruled out is it worth suspecting a clogged part or a worn-out softener. Work through the checks below in order.
First, make sure the water really is hard
Test at a tap you know is on soft water. GE's manual points out that "the installer may have isolated some fixtures (outside faucets, toilets, etc.) from soft water," and that a mixing faucet can fool you, such as a single-lever kitchen faucet whose cold side is plumbed to hard water.[1] Inexpensive hardness test strips work for a quick check at a bathroom sink.
The most common causes
For no soft water, GE's troubleshooting chart lists these four first, under the heading "Most Common Problems."[1]
No salt, or not enough. GE's chart says: "Not enough salt—should be at least 1/3 full."[1] Without salt there is no brine, and without brine the resin cannot recharge.
A salt bridge. A bridge is a hard crust: in GE's words, the "salt solidifies above water level so that brine water is not in contact with salt."[1] The tank looks full but the softener is starving. GE and Whirlpool both say it is "usually caused by high humidity or the wrong kind of salt."[1][2] Probe straight down with a broom handle and break the crust gently. Whirlpool's manual warns: "Do not use any sharp or pointed objects as you may puncture the brine tank."[2] After you clear a bridge or add salt, start a manual recharge rather than waiting for the next scheduled one.[1]
The bypass valve. It is easy to leave a softener in bypass after a filter change or a plumbing job. GE's chart lists: "Bypass valve in “Bypass” position—handle should be in the “OUT” (service) position."[1] On other models the handle or knob may work differently, so check your manual for which position is service.
The hardness setting. GE lists "Hardness setting too low." as a top cause.[1] Set the control to your real hardness in grains per gallon; if your report shows mg/L or ppm, divide by 17.1 to get grains per gallon.[1] On a well, also allow for iron: GE's instruction is to add 5 grains to the hardness setting for every 1 ppm of clear-water iron.[1] And retest occasionally, because "Water hardness can change over time, especially in well water."[1]
Hard water only some of the time
During a recharge, the softener steps aside: on GE's units, "HARD WATER is bypassed to house faucets during recharge," and if you run hot water then, "the water heater will refill with hard water."[1] GE's factory recharge starts at 2:00 AM and takes about 2 hours.[1] If the clock is wrong, recharges happen while you are showering.
Power is the usual reason the clock is wrong. GE says "the electrical outlet for the softener should be live so it cannot be accidentally switched off."[1] Its control "keeps correct time for 24 hours" without power, but after a longer outage "recharge may occur at the wrong time of day" until you reset it.[1]
When the brine is not being drawn
If the salt and settings are right but the brine level never drops, the softener cannot pull brine into the resin tank. Two things cause most of these.
The drain hose. GE warns: "Any restriction in the drain hose may prevent proper operation of the nozzle and venturi and reduce or prevent brine draw during recharge."[1] Look for a kink, a clog at the end, or a hose run too high.
The nozzle and venturi. This small part makes the suction that moves brine. GE says: "If it becomes plugged with sand, dirt, etc., the water softening system will not work and you will get hard water."[1] The manuals show how to take it apart and wash it in warm water with the softener bypassed. Whirlpool's manual adds a test afterwards: "If the water level does not drop after a recharge, the problem has not been resolved."[2] The brine tank cleaning guide covers the tank side of this.
Iron, chlorine and worn resin
On well water, iron can be the problem. Virginia Cooperative Extension says "Water softeners can also be used to remove small amounts of iron and manganese (with combined concentrations less than 5 mg/L)."[3] GE is specific: "A water softening system will not remove any iron that makes the water cloudy or rusty as it comes from the faucet," and "To take red water iron out of water, or over the maximum of clear water iron, an iron filter or other equipment is needed."[1] For iron problems, see why tap water looks rusty.
On chlorinated water, the resin wears faster at high levels: "Softener resins may degrade in the presence of chlorine above 2 ppm."[1]
Older or manual units need more attention too. Extension notes that regeneration can be automatic, semiautomatic or manual, depending on the system,[3] so check that yours is actually set to recharge on its own.
Stop and call a pro if
- The brine level stays high after you have cleared the drain hose and cleaned the nozzle and venturi.
- The control shows an error code, or the valve motor does not turn during a manual recharge.
- Resin beads show up at faucets. GE lists a cracked distributor or a unit plumbed backwards as the cause; that is a repair.
- The softener leaks, or its piping, drain or bypass needs changing. The Virginia Uniform Statewide Building Code requires a permit for installations or alterations involving the water supply and distribution system.[4]
- Your well water has iron, odour or colour that the softener is not designed for. A certified lab test is the next step, as Extension advises before choosing treatment.[3]

Common questions
- The salt tank is full. Why is my water still hard?
- A full-looking tank can hide a salt bridge, a crust with an empty space under it so the salt never reaches the water. Probe it with a broom handle. If there is no bridge, check the bypass valve, the hardness setting, the drain hose and the nozzle and venturi, in that order.
- Why is my softener not using any salt?
- A demand-controlled softener may simply use little salt. If the level has not moved in weeks and the water is hard, GE's chart points to a salt bridge or a plugged nozzle and venturi.
- Why is my water hard only some of the time?
- Usually because hot water was used during a recharge, when the softener sends hard water to the house and the water heater refills with it, or because the hardness setting is a little too low for how hard your water really is.
- How long does softener resin last?
- It varies with your water. GE warns that softener resins may degrade in chlorine above 2 ppm. A softener that still does not soften after the salt, settings, drain and venturi check out may need its resin or valve serviced.
- Could the problem be iron rather than hardness?
- Yes, on many wells. Extension says softeners can remove only small amounts of iron and manganese, with combined concentrations less than 5 mg/L, and GE's manual says a softener will not remove iron that comes out of the tap already cloudy or rusty. That needs an iron filter or other treatment.
