replaced spray arm, but this did not resolve the problem. The troubleshooting guid (inside kick panel) indicated the check valve may be stuck. We had quite a bit of lime build up, so I suspected the loose deposits may be stuck. I removed all of the deposits, disassembled the lower unit.
Removed lower spray arm, removed spry tube. The tube is two pieces. first the upper portion must be removed (two screws-place towel on base of tub to preven screws from falling into the chopper area), and then the lower portion simply rotates clockwise 1/8 of a turn. The attachment for lower spray arm has a small plastic bearing, careful not to drop it.
The dishwaser then had to be pulled out and turned on the side. I removed the entire lower unit by removing the white tabs (3). Careful, because the unit is now free to drop into the tub. Next I removed the pump. This is tricky as you have to remove the aluminimum bracket to get to the mountin bolt. The bolt turns out easily w/socket and extension. The pump motor is then rotated counter clockwise, and pulled from the pump. Takes a little force as the gasket makes for a tight fit.
I then removed the choper / pump unit from the basin. The build up behind the chopper screen was extensive, so I had to remove the screen and then the chopper cover. After cleaning, the check valve was unplugged and I reassembled the unit.

Dishwasher works great now.
