TROUBLESHOOTING
SYMPTOM
Disconnect switch is off
Fuse is blown or circuit breaker tripped
Starting switch is defective
Motor will not run
Wires at motor are loose,
disconnected, or wired incorrectly
Pressure switch contacts are dirty
Motor is wired incorrectly
Motor runs hot and
Voltage is too low
overload kicks off
Pump cycles too frequently
Pump in new installation did not pick up
prime through:
1 .
Improper priming
2 .
Air leaks
3 .
Leaking foot valve or check valve
Motor runs but no
water is delivered*
Pump has lost prime through:
1 .
Air leaks
* Stop pump;
2 .
Water level below suction pipe inlet
then check prime
3 .
Faulty check or foot valve .

Foot valve or strainer is plugged
Unscrew priming
Ejector or impeller is plugged

Pipes are frozen
Foot valve and/or strainer are buried in
sand or mud
Water level is too low for shallow well

P15003 (12-15-22)
POSSIBLE CAUSE(S)
CORRECTIVE ACTION
Be sure switch is on .
Replace fuse or reset circuit breaker .
DISCONNECT POWER; Replace starting switch .
Refer to instructions on wiring (Page 8) . DISCONNECT POWER; check
and tighten all wiring .
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.
Refer to instructions on wiring .
Check with power company . Install heavier wiring if wire size is too small (See
Electrical / Wiring Chart) .
See section below on too frequent cycling .
In new installation:
1 .
Re-prime according to instructions .
2 .
Check all connections on suction line, AVC, and ejector with soapy water or
shaving cream .
3 .
Replace foot valve or check valve .
In installation already in use:
1 .
Check all connections on suction line and shaft seal .
2 .
Lower suction line into water and re-prime . If receding water level in well
exceeds 25' (7 .6M), a deep well pump is needed .
Clean foot valve or strainer .
Clean ejector or impeller .
Replace check valve or foot valve .
Thaw pipes . Bury pipes below frost line . Heat pit or pump house .
Raise foot valve and/or strainer above bottom of water source . Clean foot valve
and strainer .
A deep well jet will be needed if your well is more than 25' (7 .6M) depth to water .
A new nozzle and venturi combination may be needed .
Replace with plastic pipe where possible, otherwise with new steel pipe .
Use larger piping .
DISCONNECT POWER; adjust or replace pressure switch .
Close faucets .
Clean venturi, nozzle or impeller .
Drain tank to air volume control port . Check AVC for defects . Check all
connections for air leaks .
Check connections .
Replace foot valve .
Adjust or replace pressure switch .
DISCONNECT POWER and open faucets until all pressure is relieved .
Using tire pressure gauge, check air pressure in tank at valve stem located on
the tank . If less than pressure switch cut-in setting (30-50 PSI), pump air into
tank from outside source until air pressure is 2 PSI less than cut-in setting
of switch . Check air valve for leaks (use soapy solution) and replace core if
necessary .
When pump has picked up prime, it should pump solid water with no air .
Suction pipe is sucking air . Check joints for leaks with shaving cream .
Consult factory about installing a sleeve in the well
Lower foot valve if possible, otherwise restrict pump discharge
