20 Most Recent Samsung DMT300RFW Builtin Dishwasher Questions & Answers

If three lights are blinking (normal, heavy, quick)... I just had this same problem, and I think I figured it out. There was water on the bottom from the last cycle, so I pressed HEAVY and DELICATE at the same time for 3 seconds (you'll see it printed on the control panel), and the unit drained. I was then able to start the new cycle normally without the error. Hope that helps!

Yeah, you're probably going to have to replace that case-brake assembly. Fortunately, they're not very expensive. Check with SearsPartsDirect.com or RepairClinic.com If you need further help, reach me via phone at https://www.6ya.com/expert/ronald_e6b9572cebe3ad27

A lot of these Samsung dishwashers don't have fuses; or the fuses are incorporated (soldered in and sealed) inside the dishwasher controller (electronic control module); which is unfortunate, because it means that you have to replace the whole electronic control module, which is a fairly expensive proposition.

What do you mean, it won't "run past the wash cycle"? Do you mean it stays in the wash cycle forever? Or do you mean it quits in the wash cycle and doesn't rinse or dry? If you need further help, reach me via phone at https://www.6ya.com/expert/ronald_e6b9572cebe3ad27

Usually caused by a draining problem. Check your drain hose where it goes into you garbage disposal. That drain hose should be mounted up so water from the sink and garbage disposal can't backwash into the dishwasher. Use a clamp or zip tie to mount the drain hose so it goes up at least 4 to 6 inches above the garbage disposal port.

Flip the unit onto its face (put down towels first to protect the face and catch the water that will spill out. Remove the square white access cover on the bottom by removing the 2 screws and gently prying the tabs. Now you see the connection to the drain pump. Disconnect here and route the hose out by removing the metal side cover and snapping open the plastic hose guides. The hose is 13 feet long and routes up the side to prevent water from draining to your d/w from your sink, so a universal replacement won't work, you have to get a new one from samsung.

i have a samsung DMT300 Series. The heavy light keeps blinking. How do I reset it? It was leaking water and I believe we fixed it. What can I do?
