When the power goes out, a softener can lose its clock, its programmed settings, or both. Some units hold their settings through an outage and some do not. Whether you reset it yourself depends on what the display shows and what your model's manual says, not on guessing. Use this as a decision guide.
Check the display first
Look at the controller once power returns. If it shows a steady clock with no warning symbol, the unit may have kept its settings. If it shows a flashing time, an error code, or a blank screen, note exactly what you see before you press anything. Write it down or take a photo. A service provider will ask for it.
Confirm the bypass is in service
Find the valve or handle setup near the unit. Your manual shows the normal service position. If the unit was left in bypass, or a valve was moved during the outage, return it to the position the manual shows. Do not force a valve.
Decide by what the manual covers
Look up the reset or time-of-day procedure in your model's manual. Many models have a short set of button steps to set the clock and the regeneration time. If the manual describes that procedure for your exact model, and you are comfortable following it, doing it yourself is reasonable. If the manual does not cover what you see, or the steps involve opening the cabinet, the drain line, or the electrical connection, stop and call your provider.
Watch for a shifted regeneration
An outage can change when the unit regenerates. Check whether it started a cycle at an odd hour, and whether a regeneration is in progress now. A cycle that runs while you are using water can be inconvenient, so note the timing and whether the water tasted or felt different.
When to call instead
- The display shows an error code the manual does not explain
- The unit will not start a regeneration after you reset it
- Water is hard again after the unit should have recovered
- You see water at the cabinet, or the unit makes unusual noises
Keep the warranty and service papers near the unit so the provider can find the model and serial details quickly. The Best Water Softeners Missouri rankings page is a starting point if you need someone to call.
