CORRECTIVE ACTION
Make sure the pump is plugged into a proper outlet.
Replace the fuse with a fuse of proper size. If tripped,

Check the size of the wiring on the circuit feeding the pump
and from the main switch on the property. If everything is OK,
contact your power company or hydro authority.
Replace the pump.

Replace the switch, after first wiping and checking that switch
is functional.
Unplug the pump, remove it from the sump, and clean the
pump and piping.
