How to Fix / Troubleshooting
Safety: Turn off power and keep hands clear of moving parts.
- Confirm source: Place a screwdriver handle against the motor body and your ear on the other end to confirm noise is from the motor, not plumbing.
- Check for leaks: Look for water dripping between the pump housing and motor flange, which can indicate a failed mechanical seal causing bearing damage.
- Short-term use: The pump may run for a short time, but noisy bearings will eventually seize and can trip breakers.
Motor bearing replacement or motor swap is required. This is best done by a motor rewind shop or pump technician familiar with Hurlcon motors.
