Delicate light flasing halfway through cycle

Model Number: DM80F600UTS
Brand: Samsung
Age: 1-5 years

Recently, & randomly, theres a beep & the delicate light flashes & stops the cycle-almost always run Normal cycle. If i power off & restart the machine most times it goes through complete cycle. I have not unplugged & reset the unit yet.

I think it should be Dw80F600

Below is info on that unit.

Try removing power from the unit first.

looks like this may be a drain error so next step woulds be to check the drain.
I often find gunk etc. where the drain hose enters the house plumbing.

Also check that all internal filters in the unit are clean.
