Jandy ePump 2.7 THP Variable Speed Pool Pump with Digital Control MECH-07 Error Fix: Pump Vibration or Resonance at Certain Speeds

Error code MECH-07 on the Jandy ePump 2.7 THP Variable Speed Pool Pump with Digital Control means: Pump Vibration or Resonance at Certain Speeds. The pump vibrates excessively, particularly at certain RPM settings — variable speed pumps can encounter resonant frequencies where vibration amplifies; check all mounting bolts and pipe union connections for tightness; verify the pump is on a level, rigid mounting pad; if vibration occurs only at specific speeds, adjust the RPM up or down slightly (50-100 RPM) to move away from the resonant frequency; persistent vibration at all speeds indicates bad motor bearings, a damaged impeller, or loose internal components
