Sudden Starts. If power is on to pump
when thermal overload resets, pump may
start without warning. If you are working on pump, you
may get an electrical shock or impeller may catch fin-
gers or tools. Disconnect power before servicing pump.
A. Pump fails to operate:
1. Check to be sure that power cord is securely plugged into outlet.
Disconnect power to outlet before handling pump or motor.
2. Check to be sure you have electrical power.
3. Check that liquid fluid level is high enough to activate switch or controller.
4. Check to be sure that there is a 3/16" (4.8mm) vent hole in discharge pipe and
it is not plugged.
5. Check for blockage in pump inlet, impeller, check valve or discharge pipe.
6. Thermal overload may have tripped. Test start pump; if it starts and then
stops immediately, disconnect from power source for 30 minutes to allow
motor to cool, then reconnect to power source. Check for cause of
overheating/overloading.
B. Pump fails to empty sump:
1. Be sure all valves in discharge pipe are fully open.
2. Clean out discharge pipe and check valve.
3. Check for blockage in pump inlet or impeller.
4. Pump not sized properly. A higher capacity pump may be required.
C. Pump will not shut off:
1. Check automatic float switch or controller for proper operation and
location. See manufacturer’s installation instructions for switches/controller.
2. If pump is completely inoperative or continues to malfunction, consult your
local serviceman.
