What causes a Samsung dishwasher to flash heavy and smart auto on control panel

Hello. The lights you describe are an error code that means over-level filling (overflow condition) and/or the leakage sensor underneath has detected water. You need to check underneath the unit for any moisture. There is a leakage sensor located at the center of the base, underneath the unit. If it detects water, it will notify the main board which will stop the unit until the condition is cleared.

Why on the Samsung DTM400 series dishwasher are normal heavy and smart/auto lights all flashing?

That's a High-temp Heating Error. It's usually caused by a bad ECS sensor. You will need to call a professional repairman to replace it. (I recommend Sears).

Low water level

I have a Samsung DMT400RHS and I started getting the low water level error ('Normal'+Heavy'+Smart Auto' LED blinking). The error started intermittently a few weeks ago, but the the last day or two the problem was solid, and simply restarting the cycle no longer worked.
I looked of the code in the dishwasher user guide and it said 'low water level.' Searched the internet and located the repair manual at for $15. The manual was well worth the $15.
The manual suggested: 1) loose level sensor connector 2) Faulty Assy case sensor or stuck floater aka 'remove foreign matter' 3) Bad Main PBA assy.
Since we do 10+ loads a week for the last 18 months the stuck floater seemed to be the most likely cause.
Go to Samsung DMT400RHS Low Water Level Error ('Normal'+Heavy'+Smart Auto' LED) (new link is click the i on each picture to see the caption - DM 04/17/2016) to see the pictures and read the captions documenting what I did. Do this at your own risk. You must turn off and disconnect the electric power and turn off the water supply before you begin.
