This is from my personal softener that the resin beads were not good 

Worked great (see video when powered on) when in use until replaced with new softener this month

PN 7252373, Model No. KA12A240040044U

The cord has a red connection on softener end that is original to unit and not a repair.

Will show signs of use.

Softener marked ESD 2502R39  7259626
