you know works. If it lights, take your pump to
Sears for service. If it doesn’t light, the electrical
circuit is faulty; consult a licensed electrician.
2. Pump starts, but blows fuses/trips circuit breakers:
After disconnecting power to pump, remove it from
sump. Remove the plate from the bottom of the pump
and make sure that the impeller turns freely. Remove
any debris obstructing impeller. If pump still does not
operate correctly, return it to your nearest Sears
Service Department for repairs.

a. Clean pump intake screen.
b. Water may be entering sump faster than the pump
can discharge it.
c. Be sure vertical distance from pump discharge
outlet to discharge pipe outlet does not exceed
specifications. See chart below.
d. Be sure discharge pipe is not plugged or frozen.
e. Be sure check valve is operating correctly.
Risk of electric shock. Unplug pump before
attempting to service or remove any component.
