Samsung DMT - 400 delicate light blinking

Have a 2 year old Samsung DMT 400 RHS. Friday last week it stopped working.We have checked for clogs in the drain hose, took everything apart clean it, No kinks in the hose and it still does not work. It starts to wash dishes, it pumps water when it is supposed to pump water out. Then when it comes almost to the end it pumps water out again stops, comes back on short time later, tries to pump again, can not pump, stops again comes back on tries to pump water out again and now the delicate light comes on and blinks. From what we can tell the pump is working fine, there are no clogs in the drain hose , nothing stopped up and no kinks. Hose is mounted the right highs and still it will not pump the water out. Can anybody help?

The Delicate light flashing on Samsung dishwashers indicates a drain error. You say there are no clogs or kinks in the drain hose, and that the drain pump tries to run (I guess you can hear it running), but it still won't drain. Try this: Disconnect the drain hose where it goes into your garbage disposal, and see if it will drain into a bucket. If it does, then there is probably a clog just inside the garbage disposal, OR if you just got a new garbage disposal, then either you or the installer forgot to knock out the plastic plug at the end of the drain port!

If the dishwasher won't drain into a bucket, then you probably have a bad drain pump, or an obstruction right there (or just inside the drain hose, which is where your check-valve is located - maybe that is where you have a clog or obstruction).

If the dishwasher drains okay, then you have a bad ECS sensor causing the error code.

I hope this helps.

Heating Element

If lights are flashing on the control panel, the heating element might have burned out. The heating element heats the water up to operating temperature. After a set amount of time if the temperature isn't reached a light on the control panel might start flashing. The heating element can be checked for continuity with an Ohm meter.

Check Fault Codes

If the display lights are flashing and there is an error code in the display window, check the wiring diagram and tech sheet in the dishwasher that will provide information on the fault.


Drain Pump

If lights are flashing on the control panel, the drain pump might not be working properly. For two-wire drain pump motors check them for continuity using an Ohm meter. If it's defective You'll need to replace it. Drain pumps are not repairable.

Touchpad and Control Panel

If the lights are flashing on the display the entire touchpad and control panel assembly might be defective. If the display works but the dishwasher functions are all out of synch, or some of the buttons don't respond properly the entire touchpad and control panel might need to be replaced.

Touchpad

If the display lights are flickering for no reason, the touchpad might need to be replaced. Sometimes when the touchpad is defective the display lights are flashing randomly.

The Delicate light flashing on Samsung dishwashers indicates a drain error. Possibly a pump/motor assy.
Samsung Dishwasher Not Draining

Doesn't sound like a clogged ECS because it's not draining at all.

Samsung dishwasher heavy and delicate lights blink and cycle stops


The lights that are blinking are indicating an error code--the particular code you describe is a "heater error". You will have to check the circuit for an open heater element, loose or broken wire, defective main control board. The part number for the main board is DE92-02256C. Hope I helped you!

Samsung Dishwasher can drain, but gives "drain error"


Sounds like it could be those same water level sensors you worked on before. Only now its telling the thing that there is water still standing in the unit. Try cleaning those sensors again and I know this sounds obvious but check all your conections.
