Kenmore Water Softener 350 Series Details

The Kenmore Water Softener 350 Series, model 625.383500, is a highly efficient system certified by NSF International against NSF/ANSI Standard 44 for hardness reduction and efficiency, and also to NSF/ANSI/CAN Standard 372. It is further certified by the Water Quality Association against CSA B483.1, affirming its robust design and performance. This model features a demand-initiated regeneration (D.I.R.) system, which intelligently monitors water usage to minimize salt and water consumption during regeneration cycles, ensuring optimal operational efficiency.

Equipped with a high-flow valve, this softener is designed to manage water flow efficiently, supporting household demands without significant pressure drops. Its electronic controller offers a range of programmable features, including setting the present time, water hardness level, and a preferred regeneration start time, typically 2:00 AM to avoid household water usage disruptions. The controller’s intuitive display provides real-time information, such as water flow bars that indicate usage and remaining recharge time during cycles.

The softener incorporates a smart salt monitor system that alerts users when salt levels are low through a flashing light on the control panel and display indicators. Users can easily set the salt level after refilling, ensuring the system consistently maintains its softening capacity. For unexpected heavy water usage, the system allows for an extra recharge to be initiated immediately or scheduled for the coming night, preventing temporary hard water supply.

Advanced optional settings provide enhanced control and customization. The Salt Efficiency feature, when activated, optimizes regenerations to operate at 4000 grains per pound of salt or higher, a requirement for installations in California. The Clean Feature is particularly beneficial for water supplies containing iron or significant sediment, introducing an extra backwash and rinse cycle before regeneration to maintain a clean resin bed, with adjustable minutes for this cycle.

Further customization includes the Maximum Days Between Regenerations setting, which can force a regeneration after a set number of days, useful for managing iron-rich water. The 97% Feature enables regeneration once 97% of the softener's capacity is utilized, conserving both salt and water. Users can also select between 12-hour or 24-hour clock formats and adjust Backwash & Fast Rinse Times to address issues like salty-tasting water.

An integrated Cleansing Feature with a screen helps capture larger sediment particles, protecting household plumbing and appliances, although it is not a substitute for dedicated pre-treatment filtration. For added convenience, a Tank Light illuminates the salt storage tank, automatically turning off after 15 minutes. The system also boasts program memory, retaining settings for several hours during power outages, ensuring minimal disruption to softening schedules.

Frequently Asked Questions (FAQs)

Can't find the answer you need? Here are some frequently asked questions about the Kenmore Water Softener 350 Series, and we answer them below.

What does the 'Demand Initiated Regeneration' feature mean?

The Demand Initiated Regeneration (D.I.R.) feature means the softener only regenerates when needed, based on your actual water usage. This intelligent system helps conserve both salt and water by preventing unnecessary regeneration cycles.

How do I set the correct water hardness for my Kenmore 350 Series softener?

Access the 'Hardness' screen via the SELECT button, then use the UP or DOWN buttons to set your water's hardness in grains per gallon. If your water contains iron, add 5 grains to the hardness setting for every 1 ppm of clear water iron to compensate.

What kind of salt should I use with this water softener?

It is recommended to use nugget, pellet, or coarse solar salts with less than 1% impurities. Avoid rock salt, block salt, granulated, table, or ice-melting salts, as they can cause issues like salt bridging or reduced efficiency.

What should I do if my water softener is not producing soft water?

First, check if there is salt in the storage tank and refill if necessary, then perform a 'RECHARGE NOW'. If the display is blank, check the power supply. If the salt level isn't dropping, inspect for a salt bridge or ensure the bypass valve is in the 'service' position. A dirty nozzle & venturi assembly could also be the cause, requiring cleaning.

How do I break a salt bridge in the brine tank?

A salt bridge is a hard crust of salt that forms, creating an empty space between the salt and the water. Gently push a broom handle or similar tool straight down into the salt in several places to break the bridge. Avoid using sharp objects that could puncture the tank.

My display is blank after a power outage, but I still have soft water. What should I do?

The electronic controller retains programming for several hours. If the display is flashing, you only need to reset the present time. Hardness and recharge time settings are usually preserved and do not require resetting unless you wish to change them.

What is the 'Clean Feature' and when should I use it?

The Clean Feature provides an extra backwash and fast rinse cycle before normal regeneration. It's beneficial for water supplies with iron or high sediment content (like sand or silt), helping to keep the resin bed clean. If your water supply doesn't have these issues, it should be set to OFF to conserve water.

How do I sanitize the water softener after installation or service?

Pour approximately 3 ounces (6 tablespoons) of household bleach into the softener's brinewell. Ensure the bypass valve is in the 'service' position, then press and hold the RECHARGE button for 3 seconds to initiate a 'Recharge Now' cycle. After the recharge completes, run 50 gallons of water through a cold water faucet downstream.

What are the electrical requirements for the Kenmore 350 Series?

The water softener operates on 24V DC electrical power, supplied by the included direct plug-in power supply. It must be plugged into a nominal 120V, 60 Hz household outlet in a dry location, properly grounded and protected by an overcurrent device.

Can this softener treat all types of iron in water?

This softener is designed to reduce moderate amounts of ferrous (clear water) iron. It will not remove ferric (red water), bacterial, or colloidal iron. For these types of iron, additional filtration or treatment, such as chlorination for bacterial iron, is usually required.

What are the warranty details for this Kenmore water softener?

It comes with a One Year Full Warranty covering all parts and labor. Limited warranties include ten (10) years for the salt storage tank and fiberglass resin/mineral tank against rust, corrosion, or failure, and three (3) years for the electronic control board against defects in materials and workmanship. Damage from abuse, freezing, or improper installation is not covered.
