TROUBLESHOOTING CHART
Symptom Possible Cause(s) Corrective Action
Motor will not run 1. Disconnect switch is off 1. Be sure switch is on
2. Fuse is blown or circuit breaker tripped 2. Replace fuse
3. Wires at motor are loose, disconnected or
wired incorrectly
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.
La tension du condensateur
PEUT être dangereuse. Pour décharger le
condensateur, toucher les bornes courtes du
condensateur à l’aide d’un tournevis isolé. VEILLER
à bien tenir la poignée du tournevis en faisant cette
manœuvre.
4. Defective Motor 4. Replace motor
5. Voltage selector switch not properly set. 5. Disconnect power, set voltage selector switch
(Figure 5) to match line voltage. (See electrical
connections page 7).
6. Low supply voltage 6. Contact an electrician
Motor runs hot and overload kicks off 1. Motor is wired incorrectly 1. Refer to wiring instructions
2. Low supply voltage 2. Contact an electrician
3. Pump house not properly vented 3. Be sure pump has sufficient ventilation to cool the
motor
Motor runs but no water is delivered
NOTE:
Check to make sure the pump is
properly primed 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:
1. New installation:
a. Improper priming a. Re-prime according to instructions
b. Air leaks b. Check all connections on suction line
c. Leaking foot valve c. Replace foot valve
2. Pump has lost prime through: 2. Existing installations:
a. air leaks a. Check all connections on suction line and shaft
seal
b. water level below suction of pump 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. Impeller obstructed 3. Clean impeller
4. Check valve or foot valve is stuck in closed
position
4. Replace check valve or foot valve
5. Pipes are frozen 5. Thaw pipes. Bury pipe below frost line. Heat pit or
pump house
6. Foot valve and/or strainer are buried in
sand or mud
6. Raise foot valve and/or stainer above well bottom
7. Low supply voltage 7. Contact an electrician
Pump does not deliver water to full ca-
pacity 1. Water level in well is lower than estimated 1. Reposition pump to minimize lift (25ft max lift)
2. Steel piping (if used) is corroded or limed,
causing excess friction
2. Replace with plastic pipe where possible,
otherwise with new steel pipe
3. Piping is too small in size 3. Use larger piping
4. Low supply voltage 4. Contact an electrician
Air Suction 1. Loose fittings 1. Tighten fittings
