Does the regeneration cycle of the BWT A6X - R22 water softener eliminate all bacteria from the water?
Frequently Asked Questions - 04/02/2026
Response Notice-Facile

The regeneration cycle of the BWT A6X - R22 water softener is primarily designed to remove calcium and magnesium ions responsible for water hardness. This process helps prevent scaling in pipes and household appliances.

However, this cycle does not eliminate all bacteria present in the water. The water softener is not a disinfection or microbiological purification system. To effectively reduce the presence of bacteria, it is necessary to use complementary solutions such as:

  • Specific antibacterial or activated carbon filters.
  • UV treatment systems.
  • Appropriate chemical treatments, depending on water quality and needs.

In summary, the regeneration cycle improves water quality by reducing its hardness, but does not guarantee bacteria-free water.

How to adjust the BWT A6X - R22 water softener?
Frequently Asked Questions - 25/01/2026
Response Notice-Facile

Initial programming: To program your BWT A6X - R22 softener, press the M button for 3 seconds until the LANG message appears. Then follow the successive steps, confirming with OK at each parameter: language configuration, time, type of salt used, volume of resin in liters, hardness unit (keep °F for France), inlet hardness (measured beforehand at your home or known via your water distributor), and finally the desired outlet hardness.

Adjustment of residual hardness: This crucial adjustment is made via two knobs located at the back of the valve. Start by turning knob 26 completely counterclockwise, then screw knob 27 to its maximum position: the outgoing water will then be 100% softened. Then turn knob 26 half a turn clockwise to achieve a slight mitigation. Open a downstream water point and measure the hardness with a test kit.

Adjustment for low and high flows: For small consumption flows, use only knob 26 (turn clockwise to increase hardness, counterclockwise to reduce it). For large flows, open the downstream water point wide and adjust with knob 27 (unscrew to increase hardness, screw to reduce it). The general goal is to achieve a residual hardness between 12 and 15 °F, a value balancing treatment efficiency and preservation of beneficial elements in the water.

Resin regeneration: Regeneration occurs automatically according to your programmed settings. You can also trigger it manually by holding the OK button for 5 seconds. During regeneration, three phases are displayed successively: REGE 1, REGE 2, and REGE 3. Maintain a sufficient interval between each regeneration to avoid unnecessary waste of salt and water.

Essential maintenance: Regularly check the salt level in the tank; the bottom of the tank should always be covered with a layer of undissolved salt over its entire surface. Use only specialized salt for water softeners (EN 973 NaCl standard). Replace the filter every 6 months or if a pressure drop occurs. Regularly measure the outlet hardness to ensure the device is functioning correctly.

When and how to add salt to a BWT A6X - R22 water softener?
Frequently Asked Questions - 27/11/2025
Response Notice-Facile

To ensure the proper functioning of your BWT A6X - R22 water softener, it is important to know when and how to add salt to the dedicated tank.

When to add salt?

  • Regularly check the salt level in the tank, ideally once a month.
  • If the salt level is below the recommended fill line or if the tank seems almost empty, it is time to add salt.
  • An insufficient salt level can compromise the effectiveness of the softener and lead to incorrect operation.

How to add salt?

  1. Open the salt tank cover of the softener.
  2. Use only salt specifically designed for water softeners, usually granulated or tablet salt.
  3. Pour the salt into the tank up to the recommended level, avoiding overfilling to prevent blocking the internal mechanisms.
  4. Carefully close the tank cover.
  5. After filling, it is advisable to check the proper functioning of the device during the next cycle.

By following these steps, you ensure quality softened water and the longevity of your device.

How to start a regeneration cycle on a BWT A6X - R22 water softener?
Frequently Asked Questions - 25/11/2025
Response Notice-Facile

To start a manual regeneration cycle on your BWT A6X - R22 water softener, press and hold the OK button on the control panel for at least 5 seconds. This action immediately triggers the regeneration, regardless of the remaining capacity of the device.

As soon as you hold the OK button for 5 seconds, the cycle starts automatically. The screen will successively display the three regeneration phases: REGE 1, REGE 2, and REGE 3. For each phase, the screen indicates the remaining time in minutes and seconds. For example, REGE 1 may last about 45 seconds, REGE 2 up to 18 minutes, and REGE 3 a few additional minutes depending on your device's configuration.

During regeneration, the softener does not provide softened water. A brief press on the OK button at any time allows you to force the transition to the next phase (a useful function for testing). Let the regeneration complete naturally to ensure a thorough treatment of the ion exchange resin.

Once the cycle is completely finished, the screen will return to the SERV display with the remaining capacity in liters. At this point, the device will automatically resume its normal operation and provide softened water again.

After a manual regeneration, check that the salt tank contains enough undissolved salt. If the device displays VERIF with SEL alternating, it means that regenerating salt is missing: refill the tank and update the level by pressing the dedicated salt button for 5 seconds.

BWT A6X - R22 - SOFTENER WORKING PRINCIPLE - 1

INSTALLATION - OVERVIEW

The softener installation involves the elements listed and pictured here below. Please refer to the Scope of Delivery sheet, which specifies which elements are delivered with your softener.

  1. Softener
  2. Controller unit
  3. Salt tank
  4. Salt tank lid
  5. Brine valve
  6. Power supply
  7. Pre-filter
  8. Drain tube
  9. Brining tube
  10. Salt tank overflow
  11. Siphon
  12. Bypass

  14. Tap for gardening usage
  15. Clamps 1

It is under the installer's responsibility to make sure that the installation does not generate any water hammer which could damage the proper work of the softener.

Our softeners are equipped with a check valve on the water inlet connection flange. The check valve may exit the flange under extreme operating and mounting conditions. To avoid this phenomenon, it is mandatory to connect the softener with flexible hoses (according to diagram here below).

We also recommend to install a leak detection system (e.g. BWT AQASTop).

CAUTION : Do not insert a reduction or an adapter between the softener connection flange and the flexible hose. The flexible hose of the same diameter as the flange must have a gasket that keeps the check valve locked in its housing.

SETTING

At its first start-up, the device displays after a few seconds the message SERV, first step of the setting, which uses 5 keys:

KeyNameFunction
←MLeft / Menu• Activates the menu with a long press (5 seconds) • Ongoing setting cancellation without record
Down• Down move within a list of choices • Decrease / change of a parameter
Up• Up move within a list of choices • Increase / change of a parameter
Right• Move from left to right digits (example: hours to minutes) • Information on the salt level during filling
OKEnter• Enter into a menu • Setting validation • A long press (5 seconds) triggers a manual regeneration. During this process, a brief press forces the trigger of the next step.

The following steps are necessary and sufficient to set the softener.

You just need to know the hardness of the raw water (concentration in lime scale), measured before or known from the public water distribution network.

First press 3 seconds on the key M, until the message LANG appears on the display.

COMMISSIONING

RINSING

The softener displays the message: REGE?

Press the OK key (once or 3 times, depending on your model). REGE 1 is displayed and a complete regeneration starts.

Progressively open the bypass tap water flows from the hydraulic block to the drain through the evacuation tube. Let it flow in order to fully rinse the softener.

Stop this rinsing by pressing OK during 5 seconds. Then SERV is displayed on the screen.

RESIDUAL HARDNESS SETTING

The hardness is measured in degrees (French °f or German °dH degrees)

1^ = 10 milligrams of "lime scale" in one liter of water

1^ = 1.78^

The hardness measurement is done with a kit of reactive stripes or colored reactive liquid. See further, in the chapter Routine maintenance.

It is possible to blend the softened water produced by the device with raw water, using a blending unit located on the rear side of the hydraulic block, in order to reach a residual hardness of few degrees (value depending on the country habits).

First, turn counterclockwise the knob (26) at its maximum. Then screw the knob (27) until it reaches its lowest level. Thus the outlet water is fully softened (hardness = 0°)

Then turn clockwise the knob (26) of half a turn. The outlet water is then slightly blended with raw water.

Slightly open any tap downstream from the softener (or use the sampling tap of the bypass) and measure the water hardness at this point. Use the knob (26) to tune the hardness for low consumption flow rates:

  • Clockwise to increase it

  • Counterclockwise to reduce it

For hardness tuning at high flow rates, largely open a tap downstream of the softener and measure again the hardness.

Use this time the knob (27) to tune the hardness: - Unscrew to increase it

  • Screw to decrease it

BWT A6X - R22 - RESIDUAL HARDNESS SETTING - 1

NOTE: it is under the user's responsibility to define the residual hardness compatible with the equipment installed downstream of the softener.

TROUBLE SHOOTING

IssuesRoot causesHow to fix
The displays shows alternative CHECK and SALTThere is not enough salt left in the tank OR The device detects a regeneration flaw.Refill the tank with salt. If it does not look to need refill, contact the technical service.
The recorded time is wrong.The seasonal time change has not been done OR A power cut occurred and the data recovery did not work (battery KO).Reset the timing (see chapter SETTING). If the problem comes up again, contact the technical service.
No displayThe power is off OR There is an electric or electronic failure.Check the power outlet where the device is plugged. If the power outlet works, contact the technical service.
Water flow through the evacuation tube (8)The device is regenerating (which means that there is no problem) OR The internal components meet a failure.Check that the device displays REGE 1, REGE 2 or REGE 3. If not, contact the technical service.
Water overflow from the salt tank (10)The brining chain does not properly close or leaks.Check the connection between the bring tube (9) and the brine valve (5). If the problem remains, contact the technical service.
The water delivered by the device does no longer look softened (lime scale coming back, etc.)Many possible root causes. Step through all the checks on next column.Measure the residual hardness once first, then after each of the following steps until the result is OK. Check that the bypass is open to direct the water to the softener. If not, change its position. Check that there is still salt in the tank. If not, refill it. Check if the type of salt is well selected in the programming. Check that the filter element is not clogged. If so replace it. Go again through the blending procedure (see chapter COMMISSIONING) If the problem remains, contact the technical service.
The connection to the Best Water Home app cannot be established.No recognized signal between softener and smartphoneCheck the connectivity activation on the smartphone. Use a compatible smartphone running a recent version of Android or iOS. Make the 1st connection within 70cm of the softener head. For the following ones, the distance depends on the environment, but can exceed 12m. Connect only one device at a time to the softener. Activate "Disconnect my softener" before trying again. If the problem persists after 5 attempts, contact customer service.

APPLICATION USAGE

INSTALLING THE APPLICATION

  1. Download the "Best Water Home" application and check that all smartphone updates are done.
  2. Open an account by following the instructions.
  3. Select the softener from the lists of devices with or without code.
  4. Activate the smartphone's Bluetooth.
  5. Start synchronisation in the direct vicinity of the softener in use.
  6. After a few seconds of synchronization, the application is connected to the softener. The data refresh displays the salt level and water consumption.

UPDATING THE SALT LEVEL

After each salt recharge, press the SEL/SALT button of the softener for 5 seconds. The word "LEVEL" appears on the softener display. Use the up and down arrows to select the salt level reached in the salt tank of the softener as indicated on the scale in the tank well.

Start the synchronization on the application: the salt level is up to date!
