Had a similar problem with a Samsung washing machine here in the UK, one of the more expensive models too. After just a few months, it developed problems.

I had to spend hours on the phone to their support people, who would tell me to reset it, switch it off and on again, wait a few days and try again etc - just... useless. I practically had to bed them to send someone round. Eventually they agreed, and a local repair guy came round - he spent a few minutes looking at it, declared it a write-off, and told me he advises all his customers to avoid Samsung!
