Troubleshooting

SYMPTOM POSSIBLE CAUSE(S)
Motor will not run Disconnect switch is off
Fuse is blown or circuit breaker tripped
Starting switch is defective
Wires at motor are loose,
disconnected, or wired incorrectly
Motor runs hot and Motor is wired incorrectly
overload kicks off
Voltage is too low
Pump cycles too frequently
Motor runs but no Pump in new installation did
water is delivered* not pick up prime through:
1. Improper priming
2. Air leaks
3. Leaking foot valve or check valve
* (Note: Stop pump; Pump has lost prime through:
1. Air leaks
then check prime
2. Water level below suction pipe inlet
before looking for
other causes.
Foot valve or strainer is plugged
Unscrew priming
plug and see if water
Ejector or impeller is plugged
is in priming hole).
Check valve or foot valve is stuck shut
Pipes are frozen
Foot valve and/or strainer are
buried in sand or mud
Water level is too low for centrifugal
setup to deliver water
Pump does not Water level in deep well is lower than
deliver water to full estimated
capacity
Steel piping (if used) is corroded or
limed, causing excess friction
Piping is too small in size
Air leak in suction line
Need more driven points

CORRECTIVE ACTION
Be sure switch is on
Replace fuse or reset circuit breaker
DISCONNECT POWER; Replace starting switch
Refer to instructions on wiring (Pages 7 and 8). DISCONNECT POWER;
check and tighten all wiring.
Capacitor voltage may be hazardous. To discharge
capacitor, hold insulated handle screwdriver BY THE HANDLE and
short capacitor terminals together. Do not touch metal screwdriver
blade or capacitor terminals. If in doubt, consult a qualified electrician.
Refer to instructions on wiring
Check with power company. Install heavier wiring if wire size is too small
(See Electrical / Wiring Chart).
See section below on too frequent cycling
In new installation:
1. Re-prime according to instructions
2. Check all connections on suction line
3. Replace foot valve or check valve
In installation already in use:
1. Check all connections on suction line and shaft seal
2. Lower suction line into water and re-prime. If water level in well
exceeds 20 feet, a deep well pump is needed.
Clean foot valve or strainer
Clean impeller
Replace check valve or foot valve
Thaw pipes. Bury pipes below frost line. Heat pit or pump house.
Raise foot valve and/or strainer above bottom of water source.
Clean foot valve and strainer.
A deep well jet pump and package may be needed (over 20 ft. to water) to
deliver water to full capacity
A deep well jet pump and package may be needed (over 20 ft. to water) to
deliver water to full capacity
Replace with plastic pipe where possible, otherwise with new steel pipe
Use larger piping
Check all connections, inspect line for cracks (test with soapy water while
pump is running - a leak will pull soap suds into hole)
Add driven points to suction line until performance in O.K.
