Kenmore dishwasher has stopped draining.

Remove the kick panel below the door, place a pan, etc under where the drain hose connects to the drain extension tube, and slide the clamp back some so you can slide the hose off of the extension tube (white plastic tube) and drain any excess fluid into the aforementioned pan, etc., then unscrew the extension tube and check for plugs, or restrictions.
the sump may also be pluged beneath the strainer assembly, and that requires removing the lower spray arm, the water tube that runs up the inside back of the unit, and the upper parts of the assembly below them to access the drain/pump sump area.
last but not least the impeller is jamed and might be able to be freed by removing whatever has lodged within there..
ya never know...
best of luck,
