It will need to be serviced. Could you send us a private message with your full model and serial number? http://bit.ly/2ihPL97
Mine is doing the same dang thing! Had for about 14 months now, and have only used a handful of times...usually hand wash everything, since have had to do that anyway after the"dishwasher"... please contact me, Mr. SAMSUNG moderator, @ Kqmckinnon@yahoo.com for a resolution.
My dishwasher is sucking and grinding and flashing LC.
I pulled out the washer, removed the bottom pan and dried it out without messing with any internal cables.
There was a very very small amount of moisture there.
There are are no kinks in any line.
When I put the dishwasher back it continues to flash LC.
How do I reset it?
take the sensor and tape it up somewhere, its stupid to have anyway, mines went off 3 times in a year and just damp, then turn power off to dishwasher for 24 hours and it will reset.
My does the same thing. Took it out looked at the pan and it’s completely dry. For giggles I removed it to make sure the sensors are dry and indeed they are. The manual provided zero information to help. Last Samsung device I’ll buy.
There is not a reset. The best option is to take the sensor off and tape it up high somewhere or some people have even just removed it. It is located on drain pan on bottom of unit. Poor Samsung design with over sensitive sensor. Causes LC error code when pan is just damp...not necessarily as leak. Hope this helps.
Samsung is certainly aware of this defect. They should provide us with a real fix. If it is a differently calibrated sensor so be it. My dishwasher is only 2 months old. I'll have to look to see if I am eligible for warranty service.
