Samsung WF70F5EDW4X will not drain.

I was doing a small load when my washing machine had shown a 5UD error message. I let it be as I read it could be the excess detergent. It didn't clear up and had now shown a 5E error message. I drained the water out using the emergency drain pipe and cleaned the filter. I then ran a 95°C cotton cycle as standard self clean advised by Samsung. Same thing happened it did not drain. I removed the water using the emergency pipe again and left it for a day.

The next day, water have accumulated inside the drum which smelt bad. I tried looking into the filter again and a lot of foul smelling grime have accumulated and I had a look at the drain hose at the back to see if there's a lot of accumulated grime. I poured some water into the hose and more grime came out. I did this until no more grime came out. I then did a 95°C cotton cycle as a self clean. It still did not drain but now the emergency pipe does not drain the water as well as it used to.

Any advice or should I just throw in the towel and call for a professional?
