Shaft seal depends on water for lubrication. Do not
operate pump unless it is submerged in water as seal
may be damaged if allowed to run dry.

Troubleshooting
Symptom
Possible Cause(s)
Pump is not plugged in
Blown fuse.

protector trips repeatedly, pump should be removed
and checked as to cause of difficulty. Low voltage,
long extension cords, clogged impeller, very low head
or lift, or a plugged or frozen discharge pipe, etc.,
could cause cycling.
3. Pump will not remove all water. If operating a pump
manually, and suddenly no water comes out of the
discharge hose, shut off the unit immediately. The
water level is probably very low and the unit has
broken prime.
Risk of electric shock. Can shock, burn
or kill. Before attempting to check why unit has stopped
operating, disconnect power from unit.
Corrective Action
Check and see if pump is plugged into a proper outlet.
If blown, replace with fuse of proper size.
If voltage under recommended minimum, check size
of wiring from main switch on property. If OK, contact
power company or hydro authority.
Replace pump.
Replace float switch.
If impeller won't turn, remove lower pump body and
locate source of binding.
Remove obstruction.
Replace float switch.
Replace float switch.
Remove pump and clean pump and piping.
Remove obstructed.
Remove the pump and clean the intake screen and the
impeller.
If voltage under recommended minimum, check size
of wiring from main switch on property. if OK, contact
power company or hydro authority.
Remove the pump and clean out the impeller.
Clean impeller if plugged; otherwise replace pump.
Drill a 1/16" - 1/8" (1.6mm-3.2mm) dia. hole between
pump discharge & check valve (1-2" above where the
discharge pipe screws into the pump discharge and
below the waterline).
Remove the pump and clean out the intake screen.
Be sure check valve is installed correctly.
