Samsung front load washer error code NF 

I got the same error code last night on my Samsung front loader. Unfortunately, my washer dumped all of its water into the pan before we noticed the leak. We shut it down and noticed the “nF” error code. I’m frustrated b/c I had already cleaned out the front debris trap, removed/cleaned pump and checked and cleaned all associated lines before reinstalling in laundry cabinet. Replaced water lines with braided SS. Washer ran well for 2 weeks. What could cause washer to dump all its contents?

By chance can you tell me the model number of your washer and the piece you replaced? My washer looks identical to yours but want to be sure. Thanks!

I get the error code in mid cycle during rinse and refill times, Right around 20 to 30 minutes left in a run, I push pause and it restarts, sometimes goes a minute or two sometimes several minutes before stopping again. Never seems to on final rinse spin. I don't think it's the valve because on initial fill it flows wide open, you can hear it very well. When it happens throughout the wash (10 or more times in a wash sometimes) you can hear a greatly reduced pressure running. Any cycle, any temps. Learning More: As I was writing this my washer went into rinse and refill, can hear the pressure changing about 3 times and now filling at a wide open flow, I can hear it from another room its flowing so well. I have read where Samsung was playing with EPA regulations and altering the flow rates on the mother board for different times in the wash to pass a higher rating. Since I run a tad bit lower than normal water pressure (shared private well) I'm beginning to wonder if it drops below Samsung's threshold at these times and faults out

Did this end up fixing the problem?

Mine says nf error code

Did it work?

So did this work???
