Water would not drain, upper rack position couldn't be changed
Pulled out dishwasher after checking the air gap, etc. Washer would marginally pump out water and could hear motor running on drain cycle. Usual mess from water draining out of hoses.
Ohmed drain motor at 24ohms, should be 16.3 ohms from repair manual. Noted check valve, a rubber flapper, was canted out from sealing surface.
New motor ohms at 24 ohms, installed new motor prophylactilly. Installed new flapper valve through the sump. Washer checked okay for drain cycle.
Feed tube assembly was ordered as upper rack flapper valve was worn into open on upper position due to normal use. Feed tube spinner was small, so the rubber flapper was scavenged from the new assembly and used on the old feed tube assembly.
