Congrats. I think you're in a minority. Our washing machine 'fabric softener' compartment started rusting less than a year after getting it. We had a long time and many back and forths trying to get them to acknowledge the problem. Their 'fix' initially was "don't use that". Finally - months later - they agreed to have someone come fix it, but it was going to be hundreds of dollars because we were "out of warranty". "But... we reported this to you with months left in the warranty period". "Well, tough luck" was basically the response.
My wife kept persisting - this dragged on for months - and eventually got some service rep to 'cover' this and a service guy came out. "Oh this is common - see this a lot with Samsungs in the last few years".
Relatedly, we had a dryer guy come out to fix the Samsung dryer. He indicated Samsung and LG were among the worst consumer-level brands for home appliances, based on their workload as service techs. But Samsung and LG have gigantic foot prints in the major retail outlets, so continue to get sold in to many households.
On the other hand I have their phone(S21) and I'm very happy with it.
I have all Samsung appliances at my home. They are the best appliances I have ever owned. I can't speak to their service because I have never had a single issue with any of them.
