How to Fix / Troubleshooting
Safety first: Immediately turn off power at the breaker if you smell burning. Do not continue to run the pump.
- Inspect motor and wiring: After cooling, remove the terminal cover and look for discolored wires, melted insulation, or burnt components.
- Check for mechanical drag: Spin the motor shaft by hand to ensure it rotates freely. Stiff rotation indicates bearing issues.
- Assess load: Verify that valves are open and the system is not excessively restricted, which can overload the motor.
Burning smells usually indicate serious internal damage. Have the motor and control PCB inspected and replaced if necessary.
