Waterboss Proplus 380 Details

The Waterboss Proplus 380 is engineered to provide superior water treatment, serving as a comprehensive appliance for enhancing water quality in your home. This model comes equipped with a detailed owner's manual, offering essential guidance for installation, efficient operation, troubleshooting, and part replacement. Should you encounter any operational issues, a dedicated HelpLine and online resources are available to ensure continuous support and maximum performance from your appliance.

At the heart of its operation is a sophisticated four-button controller featuring an LCD display. This interface allows users to monitor the appliance's status, initiate regenerations, and customize settings. It clearly shows the amount of soft water remaining (in hundreds of gallons or liters) and indicates regeneration cycle numbers during operation. A distinctive green waterMizer® light flashes when water is flowing, serving as a useful visual cue for verifying proper plumbing and detecting potential leaks within the system.

Maintaining optimal salt levels is crucial for the Proplus 380's efficiency. Users should ensure the salt level is always at least one-third full, refilling it when it drops below the water level in the brine cabinet. The use of clean pellet, solar, or cube type salt is recommended, with a strict caution against mixing different types or using rock salt. For those considering alternatives, potassium chloride can be used; however, it necessitates increasing the hardness setting by 12%. Important: Potassium chloride should not be used if your water contains iron and/or manganese.

The appliance includes a versatile bypass valve located on the main control valve. This feature allows users to isolate the softener for maintenance or to provide untreated water for outdoor applications like watering plants. Additionally, the bypass valve can be partially adjusted from the Service position towards the Bypass position to blend a desired amount of hardness back into the water supply. Proper pre-installation checks are vital, including verifying water pH (ideally 7 or above), iron levels, and hardness, which the Proplus 380 can treat up to 100 grains per gallon.

For consistent performance, the system requires protection from freezing temperatures. Regular maintenance includes an annual disinfection process using 4.0 fluid ounces (120 mL) of 5.25% sodium hypochlorite (household chlorine bleach) added to the brine well, followed by a manual regeneration. Advanced settings allow for customization beyond factory defaults, such as selecting salt dosages for efficiency or capacity, setting precise regeneration times (e.g., 2 AM default), and choosing between Demand or Delayed regeneration modes.

A specialized powerClean™ mode is available for water supplies with high iron content. When activated, this mode initiates a regeneration cycle every other day, utilizing 7 pounds (3.2 kg) of salt, to effectively mitigate iron buildup in the resin bed. It is recommended to run powerClean™ for at least two weeks every six months. Furthermore, the Waterboss Proplus 380 is proudly certified for barium and radium 226/228 reduction in accordance with NSF/ANSI Standard 44, ensuring comprehensive water treatment capabilities.

Frequently Asked Questions (FAQs)

Can't find the answer you need? Here are some frequently asked questions about the Waterboss Proplus 380 Water Softener, and we answer them below.


Why am I getting no soft water after regenerations?
This issue can arise from several factors: the brine cabinet might be out of salt, the drain line could be pinched, frozen, or restricted, the injector assembly might be clogged, or a salt bridge may have formed in the brine tank. Check your salt levels, ensure the drain line is clear and unobstructed, clean the injector components, and break up any salt bridges.

Why is there no soft water even if the appliance has regenerated?
If you're not getting soft water despite regeneration, first check if the bypass valve is in the Bypass position; it should be in the Service position. Also, verify that the appliance is plumbed correctly according to the installation instructions. An extended power outage might also necessitate resetting the controller's time of day.

The waterMizer® indicator is not flashing, but water is being used. What does this mean?
This suggests the appliance is not accurately metering water flow. The turbine sensor might not be detecting the magnet. You can test the sensor by removing it from the bypass housing and using a magnet on either flat side. If the sensor indicates flow during this test, then the turbine itself may need inspection or replacement; otherwise, the sensor might be defective.

What should I do if the controller display has no read-out?
Begin by confirming the transformer's power cord is securely plugged into an appropriate electrical outlet. Ensure the outlet is not controlled by an on/off switch. If the problem persists, the transformer might be faulty (test for 12 VAC output) or, less commonly, the controller's circuit board may need replacement.

Why does the appliance stay in regeneration mode?
If the appliance remains in regeneration, ensure the controller is properly seated and firmly locked onto the drive end cap assembly. Other potential causes include a defective magnet disk within the valve or a foreign object obstructing the valve body, preventing proper cycle advancement.

What causes excess water in the brine cabinet?
Excess water in the brine cabinet is typically caused by a restricted, frozen, or pinched drain line, or a plugged injector assembly. Inspect and clear any blockages in the drain line, or clean/replace the injector and its associated components.

Why does my treated water taste salty?
Salty-tasting water usually points to a plugged injector assembly or insufficient water pressure. Ensure the injector screen, nozzle, and throat are clean and free of debris. Also, verify that your water system maintains the minimum required pressure of 20 psi (1.4 bar).

What do the error messages (E1, E2, E3, E4, E5) on the controller mean?

E1 (Home not found): Cycle power by unplugging and re-plugging the transformer. Ensure the controller is fully seated.

E2 (Motor error): Check motor wiring and plug; cycle power. If it persists, the motor or its wiring may be defective.

E3 (Home offset): The controller will attempt to reset automatically. Ensure it is correctly attached to the drive end cap.

E4 (Home latched): Indicates gear teeth are not engaged, a stripped gear, or a valve jam. Cycle power to reset the system.

E5 (Memory error): This indicates a controller malfunction and typically requires replacing the controller.


How often should I refill the salt in my Waterboss Proplus 380?
It's recommended to maintain the salt level at least 1/3 full. You should refill the salt when its level drops below the water level visibly present in the brine cabinet. For convenience, many users opt to completely fill the tank during each refill.

Can I use potassium chloride instead of salt in my Waterboss Proplus 380?
Yes, potassium chloride can be used as a salt substitute. However, if you choose to do so, you must increase your water hardness setting on the controller by 12% (multiply by 1.12). It is crucial not to use potassium chloride if your raw water supply contains iron and/or manganese.

What is the powerClean™ mode and when should I use it?
The powerClean™ mode is a specialized service/maintenance feature designed for water supplies with excessive iron. When active, the appliance will regenerate every other day, consuming 7 pounds (3.2 kg) of salt per regeneration. This frequent regeneration helps to eliminate iron buildup in the resin bed. It's recommended to activate this mode for a minimum of two weeks at a time, every six months, and to use salt with an iron cleaning agent for continuous preventive measures.

How do I disinfect my Waterboss Proplus 380 water softener?
To disinfect your appliance, add 4.0 fluid ounces (120 mL) of 5.25% sodium hypochlorite (common household chlorine bleach) directly into the brine well of the brine cabinet, ensuring there is water present in the cabinet. After adding the bleach, initiate a manual regeneration cycle.

What is the 96-Hour mode for?
The 96-Hour mode is a preventative feature that ensures the appliance regenerates at least once every four days, preventing the system from going longer than 96 hours without a cycle. This mode is particularly recommended if your water supply contains iron. For municipal water with no iron, or if you will be away for an extended period (e.g., vacation), you can turn this option off.
