Does it run? If so, the impeller may have come loose from the shaft. Or the filter is plugged again. Clean the sump.

Sorry to tell you this but youre going to need to get a new one.
Try a place called "harbor freight" think you might like the prices as well as the fact they ship it really fast.
Just take a look at the online cat.
Good luck,Gary

try these things first.

Check your float it may be stuck causing the pump to keep running.

Nope, not a good thing

Hi,

The maximum lift is 18 feet.

Thanks.

check the intake of the pump. It may be clogged with sludge or debris.

Honestly I don't think so. If I remember the pump housing is ultrasonically sealed to prevent water entry and is not designed to permit opening for repair. But there is another way. If you can't replace the cord, cut off the bad section, leaving as much as you can that's still good; and wire it together with another waterproof extension cord through a water proof fountain repair cable kit. (Don't forget to use a water-resistant cable assembly or water will eventually migrate into the insulation, shorting the cable.) Here's one example. http://community.homedepot.com/howto/DiscussionDetail/Repair-Fountain-Cable-9065000000007sD By all means, this pond circuit MUST be protected by a GFCI. Water, electricity and a human body don't mix well.

Call the manufacturer.

No, The discharge check valve may be leaking and letting water drain back into tank. It is time buy a new one about $45.00

Hello Rob Gallau, Yes it shows thermal protection... but I have found the INSTRUCTIONS for your specific pump... http://littlegiant.com/media/153704/993949_2e-series_manual.pdf They only indicate how to clean the impeller... and SPECIFICALLY INSTRUCT the pump must be returned to LITTLE GIANT for any other repairs. Sorry

use a meter to test the float switch

Unplug and try freeing up the impeller by hand. You may have to remove bottom of pump to gain access.

nothing with those numbers, https://www.plumbingsupply.com/little-giant-pump-index.html

The vent pipe must be vented to an open air pipe.

new pump

Not sure about that, but you could have the tank welded, probably for much lees then replacing it.

Check for power at the outlet. Could also be the GFCI breaker tripped.

Its supposed to be controlled entirely by the float switch in the pit, etc. Its not uncommon for the pump to work or stay on even if the water level drops because the float can get hung up on the pipes, side walls, debris in the pit etc. You need to eliminate all those issues. Other issue is the float switch my be bad, hanging up or need resetting to the proper height etc. If its still a problem try replacing it with a water sensor switch instead.
