Possible Causes
Heater running without adequate water, Severe air lock, Failed circulation pump, Blocked suction or return line
How to Fix / Troubleshooting
Safety first: Leave power off until you are sure the heater will not run dry; dry firing can permanently damage it.
- Confirm strong circulation: With power restored briefly, check that water is moving forcefully from heater return jets. If not, shut power off again.
- Inspect pump: Listen for the Clearwater Spas circulation pump. If it hums but does not move water, it may be seized or air-locked.
- Check for obstructions: Inspect suction fittings and skimmer for debris that could block flow.
- Professional evaluation: If you cannot restore strong flow, have a technician evaluate the pump and heater before further use.
