TROUBLESHOOTING GUIDE
Symptom
Pump runs, but at a reduced speed.
Full light is illuminated with empty or
not-full tank condition.
Pump switch is activated, but pump
will not run.
Pump runs for 20 seconds and then
shuts off.
Probable Cause(s)
Ground wire not large enough or not solid.
Debris in pump.
Inadequate voltage.
Clogged strainer.
Discharge pressure too high.
Tank level sensor out of adjustment.
Tank level sensor wiring shorted.
Tank level sensor is stuck.
DC Model:
Inadequate voltage.
Ground or power wires not large enough
or not clean connections.
Motor solenoid damaged.
Damaged motor.
DC model pump not priming.
Flow switch mounted backwards.
Flow switch not connected.
No flow switch connected.
Red light flashes On/Off.
AC Model:
GFI tripped.
GFI will not reset, but cord, motor, and
switch are not damaged.
Damaged power cord or switch.
Damaged motor.

Installation and Operation Manual
(cont'd.)
Corrective Action
Check wire for damage, size, and
all connections.
Remove pump end plate and check for
debris.
Check for proper voltage requirements.
Clean strainer if present.
Check discharge lines for restrictions or
closed valves.
Check level sensor for proper positioning
(see installation instructions).
Check level sensor for frayed or
damaged wires.
Clean level sensor.
Check for proper voltage requirements.
Check wires for proper size,
damage and solid connections.
Check all connections and power voltage
to solenoid actuator post. With actuator
post powered at DC line voltage, the
output (motor connection) is to be at line
voltage. If not, replace solenoid.
Check motor by supplying voltage directly
to motor terminals. If motor does not run,
replace motor.
Check for plugged strainer. Check for air
leak in suction hose.
Check orientation of flow switch.
Check flow switch connection and function.
Use Jumper 2520-0118.
Check flow switch.
Check for damaged power cord and
reset GFI. If GFI will not reset, check for
damaged wiring in motor or improper
voltage supply.
Replace power cord.
Replace power cord.
Check motor by supplying line voltage
directly to motor terminals. If motor does
not run, replace motor.
