Possible Causes
Failed blower or Pump 3 motor, Loose output connector, Overloaded auxiliary circuit, Faulty control board output
How to Fix / Troubleshooting
Safety first: Turn off power at the breaker before inspecting the blower or Pump 3.
- Inspect the auxiliary device: Locate the air blower or Pump 3. Check for water intrusion, damaged housing, or burnt smell.
- Check connections: Ensure the auxiliary device plug is firmly connected to the correct output on the Aquavia control board.
- Test device separately (qualified): A qualified technician can power the blower or pump from a test supply to confirm operation.
- Replace as needed: Replace the blower or Pump 3 if it fails to run when powered directly. If it runs but P3 persists, the control board output is likely faulty and requires replacement.
