POSSIBLE PROBLEM

SOLUTION

 

 

 

 

 

Check that proper voltage (115 VAC, 60 Hz, single-phase ) is being

supplied to the pump. Also check that there is an adequate amount

 

of current (amps) to run the pump. Check power source circuit

 

 

 

 

breaker.

 

 

 

 

Check electrical connections?

If using float switches check wiring, inspect power cord.

 

 

 

 

Blown power fuse?

Replace fuse, check cause of blown fuse.

Pump Fails To Start

 

 

Impeller locked?

Disconnect power cord and check for clogging and improper impeller

 

 

clearance. Unclog pump. Check overload protection device.

 

 

 

 

 

 

 

Use multimeter to check motor insulation. Insulation resistance must

be approximately 15 megaohms. If resistance is low, disassemble

 

 

pump motor and bake windings to dry them.

 

 

 

 

Defective motor and pump
