Motor will not run 1. Disconnect switch is off
2. Fuse is blown or circuit breaker
3. Wires at motor are loose,
4. Defective Motor
5. Voltage selector switch not
6. Low line voltage
Motor runs hot and 1. Motor is wired incorrectly
overload kicks off 2. Low line voltage
3. Pump house not properly vented
Motor runs but no 1. Pump in new installation did not
water is delivered
NOTE: Check prime
before looking for
other causes.
Unscrew priming plug 2. Pump has lost prime through:
and see if water is in
priming hole.
3. Impeller obstructed
4. Check valve or foot valve is stuck
5. Pipes are frozen
6. Foot valve and/or strainer are
7. Low line voltage
Pump does not 1. Water level in well is lower than
deliver water to full
capacity 2. Steel piping (if used) is corroded or
3. Piping is too small in size
4. Low line voltage
tripped
disconnected or wired incorrectly
properly set.
pick up prime through:
a. Improper priming
b. Air leaks
c. Leaking foot valve
a. air leaks
b. water level below suction of
pump
in closed position
buried in sand or mud
estimated
limed, causing excess friction
Corrective Action(s)
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
