Washer taking way too long to finish cycle

[SPICandSPAM]

I have a 2018 Samsung washer/dryer. Washer model WF45K6200AZ/A2.  As the wash cycle nears completion, it says maybe 12 minutes left. Come back in 12 minutes and it says 19 minutes left. Come back in 19 minutes and it says 15 minutes left, and so on and on. Eventually have to just manually stop it.

Had a service agent look and he did the usual trouble shooting and diagnostics and it worked fine on an empty load, but since then, doing the same thing. He said maybe we were using too much soap. We are not.  Another service guy said I should replace the control board, but I don't want to do that without being sure that will fix it.

Samsung just tells me to do the same trouble shooting steps, but it does not solve this. What else could it be? I'm frustrated because it's not really that old and if a service agent cannot fix it, what am I supposed to do? Hoping Samsung has a better answer.

Just ran a cycle today and it went on an on for almost three hours. It seems to finish the wash but won't finish the spin cycle.

Hi there! I can definitely understand your frustration with your washer running continuously. You mentioned already trying several troubleshooting steps, and I just wanted to confirm you have tried all the steps in this link: https://www.samsung.com/us/support/troubleshooting/TSG01000997/

Once these steps are completed, if the washer still won't complete a cycle, it will require service. There’s a couple options here we can take based on your warranty status.
