What to do if my WaterBoss 900NF shows controller error messages?
- AAlan 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.
