For anyone who can't figure out what he's doing: Turn the dishwasher off Press the power button simultaneously with the L and R Booster buttons. If you don't see the Time Left screen show all icons (like in video) Power down and try again Press the Auto button Press Start Shut door You're welcome.
I think it can shows you how to test the waterwall moves or not. If yes, then the motor is goodm then you may save money to buy one and find the new motor doesn't help at all.
I have the same dishwasher. I am putting it in diagnostic mode and it runs for 10seconds and gives me a C1 error code. No where in the repair manual states any C1 error code. I contacted samsung and they said its the Temperature sensor that is faulty. So I checked the resistance of the thermistor with the chart in the book and it corresponds precisely to the chart. So the thermistor is not defective. Whats happening is that the lower dishes do not get cleaned. When i bought it used, the filters at the bottom where clogged and dirty. After cleaning it washed much better but still the bottom didnt clean. only 1 time the bottom dishes got cleaned properly. I wanted to test the waterwall if its working properly in the diagnostics, but I cant get passed the C1 error code. Its getting frustrating.
@@GregB6193 I ordered a new control board just to test if it would fix it. My machine works fine now but will test with new control board when i get it to see if COde C1 is still there. Will let you know
@@GregB6193 So I changed the Main PBA Board this morning and my original Code :C1 is gone, but a new code is now appearing (1E or E1). I then put the machine in Service Inspection Mode by pressing AUTO-DELICATE-POWER at the same time for 2sec. I chose option n2 to test the circulation pump. It tested the circulation pump, but I heard the pump was a bit noisy imo and gave me error 7E. Then I started a normal wash cycle with some dished in it and after 6 min, the machine stopped and gave me an error code 7E. Code 7E: Motor gear is out of order or Sensor Vane is out of order or Vane is blocked. (Sated in the repair Manual) But Google is saying code 7E is the Waterwall is jammed and cannot move. THAT is what the main issue was in the beginning. the bottom dishes weren't getting cleaned. But sometimes they were. Maybe the "Motor gear" that is stated in the manual is the waterwall motor. Probably is. I will take the waterwall motor out and test it on the bench. Most probably that is the main issue from the beginning and also the Main board got fried. i will post my findings here asap. @GregB6193 Update: So I took apart the Waterwall Motor and tested the resistance, and the motor had open circuit. No resistance. So I just ordered part number: DD31-00013B on ebay ( www.ebay.com/itm/313849967243 ) i also took apart the circulation pump motor, disassembled it and saw sooo much sand residue in there. Cleaned it all and reinstalled it.
Update Aug 7 2024: I changed the waterwall motor and now Dishwasher washes amazing. parts changed in this: Control Board, Waterwall Motor, Cleaned circulation pump. I did a self test again and still getting E1 Error. I might put back the old board to see if I get different results. The board I bought from ebay was used, so i cannot know if it already had error in it.
I think he puts it through a troubleshooting process. I did the same thing he did and mine stopped after the first try. It gives you a code if that part isn’t working.
Is this rare Schrodinger’s cat dishwasher diagnostic?. Everybody knows you’ll never catch sight of the Schrodinger’s cat no matter how fast you open that door on the dishwasher.....
