TROUBLESHOOTING CHART
SYMPTOM POSSIBLE CAUSE(S) CORRECTIVE ACTION
A. MOTOR WILL NOT
RUN
1. Disconnect switch is off.
2. Fuse is blown.
3. Starting switch is defective.
4. Pressure switch contacts are dirty.
1. Be sure switch is on
2. Replace fuse
3. Disconnect power; replace starting switch
4. Disconnect power and file contacts with emery
board or nail file
B. MOTOR RUNS HOT
AND OVERLOAD
KICKS OFF
1. Motor is wired incorrectly.
2. Voltage is too low.
3. Pump cycles too frequently.
1. Refer to instructions on wiring
2. Check with power company. Install heavier
wiring if wire size is too small. See wiring
instructions
3. See section below on too frequent cycling
C. MOTOR RUNS
BUT NO WATER IS
DELIVERED
(*) NOTE: Check prime
before looking for
other causes. Unscrew
priming plug and see
if there is water in
priming hole
1. Pump in a new installation did not pick
up prime through:
a. Improper priming
b. Air leaks
c. Leaking foot valve
*2. Pump has lost its prime through:
a. Air leaks
b. Water level below suction of pump
3. Ejector or impeller is plugged
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
1. In new installation
a. Re-prime according to instructions
b. Check all connections on suction line, air
volume control and ejector
c. Replace foot valve
2. In installation already in use:
a. Check all connections on suction line, air
volume control, ejector and shaft seal
b. Lower suction line into water and re-
prime. If receding water level in a shallow well
operation exceeds suction lift, a deep well pump
is needed
3. Clean ejector or impeller
4. Replace check valve or foot valve
5. Thaw pipes. Bury pipes below frost line. Heat
pit or pump house
6. Raise foot valve and/or strainer above well
bottom
D. PUMP DOES NOT
DELIVER WATER
TO FULL CAPACITY
(ALSO CHECK POINT
3 IMMEDIATELY
ABOVE)
1. Water level in well is lower than
estimated.
2. Steel piping (if used) is corroded or
limed, causing excess friction
3. Offset piping is too small in size
1. A deep well jet pump may be needed (over 25
ft. to water)
2. Replace with plastic pipe where possible,
otherwise with new steel pipe
3. Use larger offset piping
