TROUBLES-REMEDIES
A. Pump fails to operate:
1. Check to be sure that power cord is securely plugged into outlet or securely wired
into controller or switch box. 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 5 mm (3/16”) vent hole in discharge pipe 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 valve 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 switch or controller automatic floats for proper operation and location.
See installation instructions for switch/controller.
2. If pump is completely inoperative or continues to malfunction, consult your
local serviceman.
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
fingers or tools.
Disconnect power before servicing
pump.
