By applying these tips, you contribute to maintaining a healthy environment in your BWT A6X - R22 softener and limiting bacterial proliferation.

Question 3

Does the regeneration cycle of the BWT A6X - R22 water softener eliminate all bacteria from the water?

Accepted Answer

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.

Question 4

How to adjust the BWT A6X - R22 water softener?

Accepted Answer

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.

Question 5

Why doesn't the salt level decrease in my BWT CIRRUS PLUS BWT water softener, A6X?

Accepted Answer

If the salt level in your BWT CIRRUS PLUS BWT water softener, A6X does not decrease, several causes may explain this phenomenon:

1. The device is not performing regeneration

Salt is used during the regeneration cycle to recharge the resin with sodium ions. If the softener does not initiate this cycle, the salt will not be consumed. Check that the device is properly programmed to regenerate regularly.

2. Presence of a salt bridge

A compact block of salt may form in the tank, preventing the salt from dissolving in the regeneration water. In this case, you need to break this bridge manually to allow proper dissolution.

3. Problem with the valve or regeneration system

A malfunction of the regeneration valve may prevent water from circulating properly in the salt tank, which hinders the dissolution of the salt and its consumption. A check or technical intervention may be necessary.

4. Quality and type of salt used

Using unsuitable or poor-quality salt can lead to poor dissolution and thus a salt level that does not decrease. Ensure you are using salt specifically designed for water softeners, such as tablet salt or high-purity crystals.

5. Low consumption of softened water

If your water consumption is very low, the device regenerates less often, which may give the impression that the salt level remains stable over a long period.

In summary, check the proper execution of the regeneration cycles, the absence of a salt bridge, the quality of the salt used, as well as the proper functioning of the valve. These checks usually help resolve the issue of the salt level not decreasing.

Question 6

When and how to add salt to a BWT A6X - R22 water softener?

Accepted Answer

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?

Open the salt tank cover of the softener.
Use only salt specifically designed for water softeners, usually granulated or tablet salt.
Pour the salt into the tank up to the recommended level, avoiding overfilling to prevent blocking the internal mechanisms.
Carefully close the tank cover.
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.

Question 7

How to start a regeneration cycle on a BWT A6X - R22 water softener?

Accepted Answer

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.
