The thermal fuse shuts off power to the dishwasher if it overheats. If the thermal fuse blows, it will prevent the dishwasher from starting.

If the reset does not work after removing power from the dishwasher, then the next thing to try is to press the Start or Reset button to reset the dishwasher. Press for about 10 seconds.

Float Switch

The float switch may be hung up and this can cause the dishwasher to be stuck in a cycle.

Timer / Control

If your dishwasher gets stuck in a cycle first try shutting off the breaker for at least 5 minutes if this does not correct the problem you will need to replace the timer/electronic control.

The parts mentioned, 8058475/SWITCH, PRESSURE and 8058500/HOSE are Asko parts. Samsung should have their own equivalent parts, but the Asko parts should work as well... I think the Samsung parts would be less expensive?

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 would remove and examine the wash arms to see if any of the holes are plugged with food or mineral deposits. Clear any food with a paper clip. If you have mineral deposits, remove the deposits with Lime Away or CLR cleaner. Hope this helps you.

I have the same problem with my dmr77. My coffee pot ran over and evidently ran down behind the Samsung dishwasher. It thinks that it is leaking. How do you reset it?

I seem to be having this same problem... Did you ever find the solution?
