Brand new Samsung Dishwasher DW7933LRA Flashing light "HEAVY" and will not start

If your dishwasher is stuck in the drain cycle and the lights are flashing, it may be due to a faulty drain pump. You should check the drain pump and hose for any blockages or clogs. If these parts are clear, then the next step is to check the wiring between the dishwasher and the drain pump. If there is a loose wire or a broken connection, then this could be causing the issue. If the wiring seems fine, then the issue may be with the control board or the drain pump itself. If this is the case, then you will need to replace either of these parts to get your dishwasher back to working order.

I wish you had received an answer. Mine is doing the same.

That indicates a leakage error. Water has leaked down into the base of the machine. You will need to sop up and dry out all the water down in there, then find the leak, which is most commonly caused by a bad drain pump and/or drain hose. Good luck!

Had a look in the user manual for your dishwasher.http://downloadcenter.samsung.com/content/UM/201211/20121101114232459/DW7933LRASR-00141A-02.pdf

Page 26 shows blinking Heavy light means there is leakage in the dishwasher. Most likely there is water in the base under the drain sump which could cause the flood switch to trip. Turn mains power to dishwasher off. Pull it out from under kitchen bench without breaking the hoses. Put some towels on the floor and turn dishwasher back and forth on incline to get water out. Wait a little and turn on. If no difference then you need to dry the base and find the source of the leak. More likely the door seal.

Pl refer user manual. In general flashing light may mean : no water flow, salt chamber empty, door not closed etc. It all depends on the error code message designed.assigned by the manufacturer.
