SYMPTOM

POSSIBLE PROBLEM

SOLUTION

 

 

 

 

 

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

 

Incorrect voltage/amps?

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

Check for excessive bearing wear, if worn replace bearings. Replace

 

bearings?

motor if defective.

 

 

 

 

Twisted or restricted discharge

Lay hose flat un-kinked. Remove clog from hose line.

 

hose?

 

 

 

 

 

Clogged pump strainer?

Clean strainer.

Pump Fails to Deliver Full

 

 

 

Use a voltmeter to check voltage while pump is energized. Voltage

Output

 

Low voltage?

must be within ±10%. Check power source (no load and load). If an

 

 

extension cord is used, make sure it has adequate current-carrying

 

 

 

 

capacity for the required length.See Table 4.

 

 

 

 

Impeller worn?

Replace impeller.

 

 

 

Water in Seal Oil

Defective water seal?

Replace water seal.

 

 

Loose Oil Fill Plug?
