How to Resolve an E1 Error on a WaterBoss Water Softener

Quck answer

To reset an E1 error on a WaterBoss water softener, follow these steps:

1. Turn off the power to the water softener by unplugging it from the power source.

2. Wait for 10-15 seconds and then plug it back in.

3. Press and hold the “Regen” or “Reset” button on the control panel for about 10 seconds.

4. Release the button and wait for the water softener to go through a regeneration cycle.

5. Once the regeneration cycle is complete, the E1 error should be cleared, and the water softener should be functioning normally again.

Note: If the E1 error persists after following these steps, it is recommended to consult the WaterBoss instruction manual or contact their customer support for further assistance.


The E1 error on the WaterBoss water softener indicates that “Home not found.” If you encounter this error, it implies that your controller is likely not properly linked to the water softener. As mentioned in the WaterBoss instruction manual, the most effective solution for this issue is to disconnect the unit and then examine the controller connections. If doing so fails to resolve the E1 error, there may be a more severe problem with your water softener.

Step 1

Follow the power cord of the WaterBoss water softener to the electrical outlet.

Step 2

Securely grip the base of the wall plug and pull it away from the outlet to disconnect it.

Step 3

Inspect the plug that connects the water softener to the handheld controller. Push it in firmly to ensure a proper connection.

Step 4

Reconnect the power cord to the wall outlet. This will reset the system and turn off the “E1” error.

Step 5

If the “E1” error persists, repeat the process. If this doesn’t resolve the issue, contact your WaterBoss vendor for assistance.
