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
Motor runs but no Pump in new installation did
water is delivered* not pick up prime through:
1. Improper priming
2. Air leaks
* (Note: Stop pump;
then check prime
before looking
3. Leaking foot valve or check valve
for other causes.
Pump has lost prime through:
Unscrew priming
1. Air leaks
plug and see if water
2. Water level below suction pipe inlet
is in priming hole).
Foot valve or strainer is plugged
Impeller is plugged
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 shallow well
setup to deliver water
Pump does not Water level in 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
Packed well point
CORRECTIVE ACTION
Be sure switch is on.
Replace fuse or reset circuit breaker.
DISCONNECT POWER; Replace starting switch.
Refer to instructions on wiring (Page 7). 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).
In new installation:
1. Re-prime according to instructions.
2. Check all connections on suction line, with soapy water or
shaving cream.
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 receding water level
in well exceeds 25' (7.6M), 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.
Pump will not lift water more than 25 feet.
A deep well jet will be needed if your well is more than 25' (7.6M)
depth to water.
Replace with plastic pipe where possible, otherwise with new steel pipe.
Use larger piping.
Backflush well point or sink new point.
