How to troubleshoot a Liberty Pumps 404 that won't turn on or off?
- Kkiara86Jul 27, 2025
If your Liberty Pumps Water Pump isn't turning on or shutting off, first, ensure the unit is securely plugged in. Then, have an electrician inspect the wiring to confirm proper connections and sufficient capacity. Also, make sure that an unrestricted vent of at least 1-¼” in diameter is in use. Finally, remove the access cover and check that the float is free to move. If buildup restricts the float, clean and reinstall it. If the switch is defective, replace it.
