  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.

- 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.

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.
