I have a Samsung dishwasher model #DW7933LRABB that starts to run normal then I get 3 flashing lights Normal, Heavy and Smart then does not complete the cycle
The Normal, Heavy and Smart lights will blink when there is low water level in the dishwasher. Check that the sump area isn't blocked from filling with water. Often there is a float inside the tub that can be held down by a utensil that fell under the lower basket. Remove any foreign objects. Then try to run the dishwasher when it is completely empty. The parts diagram for the dishwasher is available here: https://www.searspartsdirect.com/model/60yajq87a8-001482/samsung-dw7933lrabb-aa-01-dishwasher-parts . If there isn't an obvious blockage in the water level monitors, you could have a wiring problem or an issue with the control board that doesn't get the signal for water reaching the desired level. (Note: if the incoming water pressure were too low, only the Smart light would flash.)
The manual for the DW7933LRABB is available from Sears Parts Direct on the product page: https://www.searspartsdirect.com/manual/60yajq87a8-001482/samsung-dw7933lrabb-aa-01-dishwasher . The current link to the manual is https://c.searspartsdirect.com/mmh/pd_download/lis_pdf/OWNM/1206228L.pdf .
