This pump works off of a pressure switch. You can remove the cover on the switch located on the side of the pump.You can either buy a switch repair kit, or you can open it up and take a look and see if the diaphragm is sticking. If you remove and clean the parts, you may have some success. Or, just buy the switch repair kit from your local Little Giant dealer. Good luck!

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

Hello Rob Gallau,

Yes it shows thermal protection... but

I have found the INSTRUCTIONS for your specific

They only indicate how to clean the impeller... and SPECIFICALLY INSTRUCT the pump must be returned to LITTLE GIANT
for any other repairs.

It sounds like the float assembly is getting restricted somehow. Check to see if it is hitting the cover and/or binding over normal up/down travel.

The float switch is binding

What is the age of the unit? Those batteries don't last forever and are constantly under a small charge. When the outage happened the battery discharged and the sensing circuit was able to tell that the battery was no longer any good.

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

Little Giant... | Answered on Mar 20, 2017

first do not change the factory wiring, what voltage is the pump wired for, what voltage is supplied to the pump.

then we figure out the rest
also what do the instructions say about the pump

NO stands for normally open contact-which means during operation is open which means off.

will be glad to help 865-888-1220

You have to buy a new cable ,remove the cover plate ,mark the wires before removal. (Colour) etc.Peel back the new wires and fit them exactly the same way as they came off,or get a professional to do the job.
