Samsung Dishwasher DW80K7050US drain problem - Error Code 3C

[lawsonfarms]

I have a 2 year old Samsung dishwasher.  Its giving me a 3C error code and leaving about an inch of water in the bottom.   Plumbing drain is clear, disposal is clear, drain line is not kinked.   If I hit the cancel button to make it pump manually, it seems to pump fine.  I've drained it out 2x doing it that way.  but it still stops mid cycle with the 3c error code and water in the bottom on the next cycle.   Can you tell me how to test the voltage to the pump and the pump itself?  I don't want to replace the pump only to find out it was the circuit board or the relay to the pump.

I’m having the same problem. What did you do to fix it?

3C is a circulation pump error. Either object in pump, pump failed, main board not sending power or inverter bad. 
 

Only way to know which is by using tech sheet and running tests.
