Check:
1. Tripped starter overload. Reset and check
motor and pump for proper operation.
2. Improper power supply. Check voltage and
motor nameplate data.
3. Incorrect connections. Check wiring diagram.
4. Mechanical failure. Check for free rotation
and examine bearings.
5. Short-circuited windings. Indicated by blown
fuse or failure to start. Motor must be replaced.
6. Overload. Check pump for proper operation and free
rotation.
7. One phase open in three-phase circuit. Check power
