  If your Little Giant Water Pump does not turn on, there are several potential causes. First, ensure the pump is properly connected to a dedicated circuit equipped with GFCI. Check if the circuit breaker is off or the fuse is removed, and if so, turn on the circuit breaker or replace the fuse. An accumulation of trash on the float or a float obstruction could also be the reason; in this case, clean the float and check the float path, providing clearance. Finally, a defective switch or motor could be the issue, requiring you to replace the switch or the entire pump.

What to do if Little Giant 6EC runs but does not discharge liquid?

  Jennifer HernandezAug 2, 2025
  If your Little Giant Water Pump runs but does not discharge liquid, there are several possible reasons. It could be due to a check valve installed backwards; ensure the flow-indicating arrow on the check valve body indicates proper installation. Alternatively, the check valve might be stuck or plugged, so remove the check valve and inspect it. The lift might be too high for the pump, in which case you should check the rated pump performance. The inlet to the impeller could be plugged, requiring you to pull the pump and clean it. Lastly, the pump could be air-locked; remove the pump and clean the air bleed hole.

  If your Little Giant Water Pump will not shut off, several factors could be the cause. Check for a float or float rod obstruction and ensure its path is clear. The pump may be air locked; remove the pump and clean the air bleed hole. If the liquid inflow matches the pump's capacity, a larger pump may be required. Lastly, a defective switch could be the problem, necessitating replacement of the switch.

How to troubleshoot Little Giant 6EC not delivering rated capacity?
- B
  Brandon WardAug 12, 2025
  If your Little Giant Water Pump does not deliver its rated capacity, several issues could be at fault. The lift might be too high for the pump, so check the rated pump performance. If it's a 3-phase pump, the rotation might be incorrect; switch any two of the line wires. Low voltage could cause the speed to be too slow; ensure the supply voltage matches the nameplate rating. The impeller or discharge pipe could be clogged; pull the pump and clean it, checking the pipe for scale or corrosion. Finally, impeller wear due to abrasives could be the problem, requiring pump replacement.

Why is the protector tripping on my Little Giant 6EC?
- W
  Wyatt HudsonAug 18, 2025
  If the protector is tripping in your Little Giant Water Pump, indicating motor overloading or overheating, several issues could be the cause. The pump impeller might be obstructed, requiring you to pull the pump and clean it, checking the pipe for scale or corrosion. The pump could be air-locked; shut the power off for about a minute, then restart, repeating this several times. If this doesn't work, clean the vent hole. Other potential causes include an excessively high or low voltage supply, or the pump, motor, bearings, or seal reaching the end of their useful life, necessitating pump replacement.

Why does my Little Giant 6EC cycle continuously?
- C
  contrerasstephanieAug 23, 2025
  If your Little Giant Water Pump cycles continuously, several factors could be responsible. A missing check valve in a long discharge pipe may allow liquid to drain back into the basin; install a check valve for correct operation. A leaking check valve could also be the cause; inspect the check valve. Finally, the basin might be too small for the inflow, suggesting you install a larger basin.
