Spa powers on but will not start any pumps; relays click but no water movement.

Safety: Turn off power at the breaker before touching pumps or wiring.

• Listen for sounds: When you press the jet button, if you hear a hum but no water movement, the RivieraPool pump motor may be seized or have a bad capacitor.
• Check for obstructions: With power OFF, remove the pump's rear cover and attempt to rotate the shaft by hand. If it is stuck, debris or internal failure is likely.
• Inspect wiring: Ensure all pump leads are firmly connected at the control pack and at the pump junction box.
• Capacitor replacement: If the shaft spins freely but the motor only hums, replace the RivieraPool pump start/run capacitor with the correct rating.
• Replace pump: If the motor is seized or overheats quickly, replace the entire RivieraPool pump assembly.
