Possible Causes
Failed blower triac or relay on PCB, Shorted blower motor, Damaged blower wiring harness
How to Fix / Troubleshooting
Safety first: Unplug the spa before inspecting the blower or control box.
- Inspect blower wiring:
- Check the air blower harness from the blower to the control box for cuts or burn marks.
- Ensure the connector is fully seated.
- Check blower motor:
- With power disconnected, try to spin the blower fan by hand (if accessible) to ensure it is not seized.
- Test operation: Reconnect power and briefly attempt to start bubbles. If E17 appears immediately and the blower does not start, the control circuit or blower is likely faulty.
- Replace blower first: Install a compatible Avenli air blower assembly. If E17 persists with a new blower, the main control PCB must be replaced.
