Operating voltage is too low – Use rated voltage

Cooling system has insufficient flow – Clean cooling system

Bearing failure  – Replace bearings (determine cause)

Operating voltage is too low – Use rated voltage

Single phase operating – Check power source

Impeller is blocked – Check and clear impeller

Binding between the impeller and lower casing cover or inner cover – Adjust the clearance of impeller
