TROUBLE SHOOTING AID
Motor Will Not Start.
1. Check for voltage present at connection box.
2. Check that the supply voltage matches the motor voltage connections.
3. Check that you have proper line voltage at the motor.
4. Check that all connections are sound.
5. Check that the motor shaft rotates easily by hand. (This can be checked at the rear of motor by turning
with screwdriver or wrench.)
Motor Won’t Start, But It Hums.
1. Check items 2-5 above.
2. Check that there is no foreign matter lodged between the contacts of the start switch.
3. Check to insure the capacitor is functioning properly.
4. Make sure the motor fan cover isn’t hitting the fan.
Motor Gets Hot And Shuts Down.
1. Check for proper wiring in the motor box. The supply voltage must match the motor voltage connections.
2. Check the voltage at the motor, with the motor and all other loads on the circuit running. It must not be significantly
(10% or more) above or below the nominal voltage.
3. Check to see if the motor shaft turns without excessive resistance. Bad bearings, or a clogged impeller can cause
excessive resistance.
4. Check that the pump impeller and the housing are not clogged or blocked.
Pump Will Not Hold A Prime.
1. Check for defective joints at all pipe fittings. They must all be air tight. DO NOT USE TEFLON TAPE ON THE THREADS.
Use Teflon paste.
2. Check for a defective check valve or foot valve. The pump and suction line must be full of water before start up.
3. Check for a leaking seal.
4. Make sure the drain plugs have their o-rings in place and are tight.
