I am working on this Samsung dishwasher model DMT300RFS/XAC. Customer complaint is the normal cycle will stop partway through and flash the delicate light. According to the service manual it is a draining error. I arrive and check machine... no water in the tub. I put it into diagnostics and sure enough on the first test the drain pump runs continuously and never fills. So I'm thinking the low level sensor must not be working. I proceed to change the part and I make sure the hoses are all clear. Put it back together and it works okay for the first cycle, then delicate light flashes again. The dishwasher is definitely draining as all the water is out of the tub. Not being that familiar with Samsung products, can anyone who regularly works on Samsung please lead me in the right direction? From what I understand the control needs to see that the low level sensor has told it there is no more water in the tub?
Thanks for any help.
