How to Fix / Troubleshooting
Safety first: Turn off power and allow the pump to cool before touching the motor housing.
- Allow cooling time: Let the AquaJet motor cool for at least 30–60 minutes, then attempt a restart.
- Clear ventilation: Remove leaves, dirt, and obstructions from around the motor. Ensure the cooling fan and shroud are not blocked.
- Check load: Verify that valves are open and the filter is clean to avoid overloading the pump.
- Monitor operation: If the pump repeatedly shuts off after a short run, the internal thermal protector or motor windings may be failing and the motor assembly should be replaced.
