How to Fix / Troubleshooting
Safety: Shut off power before inspecting the pump.
- Inspect for blockage: Remove the pump lid and basket, and check the impeller area for debris. Clear any obstructions.
- Reduce speed: In the automation settings, temporarily lower the maximum pump speed and see if the alarm clears.
- Check wiring and connections: Ensure the pump is wired with the correct gauge wire and that all connections are tight.
- Monitor current draw: A technician can use a clamp meter to measure pump current and compare it to the nameplate rating.
If the pump continues to trip AL2 at normal loads, the motor may be failing and should be evaluated by a professional.
