    What to do if my WaterBoss 900NF shows controller error messages?
    • A
      Alan DixonAug 6, 2025
      If you see error messages on your WaterBoss Water Filtration Systems controller, here's what to do: * **“E1” Home not found:** Unplug the transformer and plug it back in to cycle the power. The system will search for Home again. * **“E2” Motor error:** Ensure the controller is fully pushed onto the drive end cap. * **“E3” Home offset:** Ensure the controller is fully pushed onto the drive end cap. * **“E4” Home latched:** Cycle the power to reset the system. * **“E5” Memory Error:** Replace the controller.

    Why is my WaterBoss 900NF Water Filtration Systems producing salty (or purple) water?
    • M
      Michael GarrettAug 11, 2025
      Salty water (or purple water if you have an iron filter) in your WaterBoss Water Filtration Systems can be caused by several factors: * A plugged injector. Replace the injector screen, nozzle, and throat. * Low water pressure. Maintain a minimum pressure of 20 psi. * A restricted drain line or flow control. Remove the restriction. * A restricted or crimped regenerant line. Remove the restriction, and replace the line if it's crimped. * Intermittent pressure drop from the feed source. Install a check valve on the inlet water line to the appliance (check local plumbing codes first). * Excessive regeneration. Reprogram the iron filter regeneration frequency.

    How to fix no display on WaterBoss Water Filtration Systems?
    • B
      Brian RamirezAug 16, 2025
      If your WaterBoss Water Filtration Systems is showing no read-out in the display, consider the following: * **Electric cord:** Ensure the transformer is plugged in. * **Power outlet:** Check the power source and make sure the outlet isn't controlled by a switch. * **Transformer:** Test with a volt meter for 12 VAC at the control. Replace the transformer if it reads less than 10 VAC or greater than 14 VAC. * **Circuit board:** With 12 VAC present at the controller, replace the controller. * **Room temperature:** If the ambient room temperature is high, no action is necessary.

    What to do if my WaterBoss Water Filtration Systems stays in regeneration mode?
    • R
      rmcconnellAug 21, 2025
      If your WaterBoss Water Filtration Systems stays in regeneration, it could be due to: * The controller not being attached properly. Ensure the controller is pushed all the way onto the drive end cap. * A defective magnet disk. Replace the magnet disk. * A foreign object in the valve body. Remove any foreign objects from the valve body. * A broken valve assembly. Repair the drive end cap.

    Why is there excess water in the regenerant cabinet of my WaterBoss Water Filtration Systems?
    • E
      Elizabeth WalkerAug 26, 2025
      Excess water in the regenerant cabinet of your WaterBoss Water Filtration Systems (more than approximately 3–4 inches) can be caused by: * A restricted, frozen, or pinched drain line. Remove the restriction, thaw, or straighten the drain line. * A plugged regenerant line, regenerant line flow control, or air check/draw tube. Clean the flow control, air check/draw tube, and regenerant line. * A plugged injector assembly. Clean or replace the injector. Replace the throat if removed. * A sticking regenerant refill valve. Remove the valve and check for any obstruction.
