How to Fix / Troubleshooting
Safety first: Turn off and unplug the spa before inspecting the air outlet.
- 1. Inspect bubble ring:
- Check the air outlet ring inside the spa for obstructions.
- 2. Drain excess water:
- If water has entered the air line, follow the manual to drain or tilt the unit slightly (without stressing hoses) to allow water to exit.
- 3. Test again briefly:
- Reconnect power and run bubbles for a short period to see if noise improves.
- If noise remains very loud or metallic: The blower motor bearings may be failing; blower assembly or heater pump unit replacement is likely needed.
