Troubleshooting 9
Risk of electric shock. Can shock, burn or kill. Capacitor voltage may be hazardous. To discharge
capacitor, hold insulated handle screwdriver BY THE HANDLE and short capacitor terminals together. Do not touch
metal screwdriver blade or capacitor terminals. If in doubt, consult a qualified electrician.
Symptom Possible Cause(s) Corrective Action
Motor will not run.
Disconnect switch is off. Be sure switch is on.
Fuse is blown or circuit breaker tripped Replace fuse or reset circuit breaker.
Starting switch is defective. DISCONNECT POWER; Replace starting switch.
Wires at motor are loose, disconnected, or wired
incorrectly.
Refer to instructions on wiring. DISCONNECT POWER; check
and tighten all wiring.
Motor runs hot and overload kicks off
or motor does not run and only hums.
Motor is wired incorrectly. Refer to instructions on wiring.
Voltage is too low.
Check voltage being supplied to motor. Install heavier wiring if
wire size is too small (See Wiring Chart).
* Motor runs but no water is delivered.
Pump in new installation did not pick up prime
through:
In new installation:
1. Improper priming. 1. Re-prime according to instructions.
2. Air leaks. 2. Check all connections on suction line, with shaving cream.
3. Leaking foot valve or check valve. 3. Replace foot valve or check valve.
4. Pipe size too small. 4. Re-pipe using size of suction and discharge ports on pump.
Pump has lost prime through: In installation already in use:
1. Air leaks.
1. Check all connections on suction line and shaft seal with
shaving cream
2. Water level below suction pipe inlet.
2. Lower suction line into water and re-prime. If receding water
level in well exceeds 20’ (6.i m), a deep well pump is needed.
Impeller is plugged. Clean impeller.
Check valve or foot valve is stuck shut. Replace check valve or foot valve.
Pipes are frozen. Thaw pipes. Bury pipes below frost line. Heat pit or pump house.
Foot valve and/or strainer are buried in sand or
mud.
Raise foot valve and/or strainer above bottom of water source.
Clean foot valve and strainer.
*Pump does not deliver water to full
capacity.
Water level in well is lower than estimated.
A deep well jet will be needed if your well is more than 20’
(6.1m) depth to water.
Steel piping (if used) is corroded or limed, causing
excess friction.
Replace with plastic pipe where possible, otherwise with new
steel pipe.
Piping is too small in size. Re-pipe using size of suction and discharge ports on pump.
Pump not being supplied with enough water. Add additional well points.
Pump leaks around clamp. Clamp loose.
STOP PUMP, tighten clamp nut 1-2 turns. Alternately tighten and
tap on clamp with mallet to seat O-Ring. Do not overtighten.
* Stop pump; then check prime
before looking for other causes.
Unscrew priming plug and see if
water is in priming hole.
