TROUBLESHOOTING CHART

Symptom
Motor will not run
Motor runs hot and overload kicks off
Motor runs but no water is delivered
NOTE:
Check prime before looking for
other causes. Unscrew priming plug and see
if water is in priming hole.

Possible Cause(s)
1. Disconnect switch is off
2. Fuse is blown or circuit breaker tripped
3. Wires at motor are loose, disconnected or
wired incorrectly
4. Defective Motor
5. Voltage selector switch not properly set.
6. Low line voltage
1. Motor is wired incorrectly
2. Low line voltage
3. Pump house not properly vented
1. Pump in new installation did not pick up
prime through:
a. Improper priming
b. Air leaks
c. Leaking foot valve
2. Pump has lost prime through:
a. air leaks
b. water level below suction of pump
3. Impeller obstructed
4. Check valve or foot valve is stuck in closed
position
5. Pipes are frozen
6. Foot valve and/or strainer are buried in sand
or mud
7. Low line voltage
1. Water level in well is lower than estimated
2. Steel piping (if used) is corroded or limed,
causing excess friction
3. Piping is too small in size
4. Low line voltage

Corrective Action
1. Be sure switch is on
2. Replace fuse
3. Refer to wiring instructions. Check and tighten all
wiring
Capacitor voltage MAY
be hazardous. To
discharge capacitor, touch short capacitor
terminals with an insulated screwdriver. BE SURE
to hold handle of screwdriver while making
contact with capacitor terminals.
4. Replace motor
5. Disconnect power, set voltage selector switch
(Figure 5) to match line voltage. (See electrical
connections page 3.)
6. Contact an electrician
1. Refer to wiring instructions
2. Contact an electrician
3. Be sure pump has sufficient ventilation to cool
the motor
1. New installation:
a. Re-prime according to instructions
b. Check all connections on suction line
c. Replace foot valve
2. Existing installations:
a. Check all connections on suction line and
shaft seal
b. Lower suction line into water and re-prime.
If receding water level exceeds suction lift,
reposition the pump to ensure less than 25 ft. of
lift.
3. Clean impeller
4. Replace check valve or foot valve
5. Thaw pipes. Bury pipe below frost line. Heat pit or
pump house
6. Raise foot valve and/or stainer above well bottom
7. Contact an electrician
1. Reposition pump to minimize lift (25ft max lift)
2. Replace with plastic pipe where possible,
otherwise with new steel pipe
3. Use larger piping
4. Contact an electrician
