I am in the same boat as Robert. All sources claim it is an invalid model number even managemylife.com. I can confirm that the model number provided by Rober is in fact correct and valid.
I've attached a picture to show the label.
I just picked this unit up as a floor model and Sears did not have its manual nor the quick connect for the pump!
Sears parts were no help either because the unit is discontinued.
I was informed I need to go to the manual to get the name of the parts distributor (the company who actually made the Kenmore 25805. With no manual, this is kind of impossible.
So, I am looking for a source the manual and the quick connect male connector (In Canada preferably but I'll look anywhere).
