Troubleshooting Chart
Symptom Possible Cause(s) Corrective Action(s)
Motor will not run 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. 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
Motor runs hot and
overload kicks off
1. Motor is wired incorrectly
2. Low line voltage
3. Pump house not properly vented
1. Refer to wiring instructions
2. Contact an electrician
3. Be sure pump has sufficient ventilation to cool the motor
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.
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. 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
Pump does not
deliver water to full
capacity
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
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
