Angela for Model Number DMT400RHS/XAA My dishwasher won't drain, delicate light flashing. I've checked air gap and lines. took apart the inside cleaned both filters, cover, and impeller. Found dishwasher check valve broken and never found the lower half. Reassembled, not sure if I put nozzle duct seal back properly (#6 on diagram). It's flashing Heavy light. So I pulled apart bottom drain pan dried noticed water coming from turbidity sensor cleaned and replaced sensor. Now It won't drain again back to delicate light blinking. The only thing I notice was the Brake Assy has some debris in upper left. Thinking of replacing Drain pump. Thoughts?
