To anyone having this issue.
I just had this exact issue with my Samsung Flexwash WV55M9600AV. It's a communication error between the two control boards behind the front panel. It's a very simple fix you can do yourself in about 20 minutes once you have the correct parts, and save hundreds of dollars. If you order both control boards separately, it costs almost double compared to if you order them together. The part number to order them together is: DC92-02104A.
Here's a youtube link on how to remove the front panel:
Once the front panel is off, it's two connecters and about 10 screws to replace the control boards.
I'm glad I foud this thread. My new samsung washer is flashing the same code. 18:8J. Bottom washer will not power on. The top one will power on but flashes 18:8J on the display screen for the bottom washer. Trying to clarify...was the fix a control board under the display panel or the 2 control boards behind the washer?
I have exatcly the same problem on my 11-month old Samsung Flexwash WV55M9600AW. 18:8J blinks along with delay end button, self clean button and smart connect button. Called Samsung Customer Service today and scheduled my service appointment for next Wednesday. Now, I am keeping my finger crossed with the hope this problem can be fixed. I will provide a follow up update and let you folks about the outcome of the Samsung's service.
i have same issue in my brand new washer. it was not working at the time of delivery. Tech will swap its control board but I dont know how well to trust the samsung appliance now. I want to return it but each time their new delivery is either broken or damaged( already hapenned twice). I dont trust samsung appliance anymore.
