Jandy VS FloPro 1.85 THP Variable Speed Pool Pump MECH-02 Error Fix: Motor Bearing Noise

Error code MECH-02 on the Jandy VS FloPro 1.85 THP Variable Speed Pool Pump means: Motor Bearing Noise. The pump motor makes grinding, humming, or squealing noises — motor bearings (front and rear) wear out over time and from exposure to moisture, heat, and vibration; early bearing failure manifests as a low hum that progresses to grinding; excessive bearing noise means replacement is urgent; replacing motor bearings requires removing the motor from the pump, pressing out old bearings, and pressing in new ones; many pool owners opt for a complete motor replacement rather than bearing-only repair due to the labor involved
