Remove the top cover and the inlet protector cover and clean everything. Gene.

Remove the water feeding tube for the upper spray arm. Remove 4 screws (#3 on the break down diagram) holding the top cover (#1 on the break down diagram). Remove the inlet protector (#8) holding by the tab on the right side. Check the chopper (#6) for any clog. Clean all debris and assemble in the reverse order. Gene.

The check valve is on the right side of the chopper, a black thing stuck in the housing. Check valve P# 8268375; chopper assy. P# 8268383
