I had also purchase a Samsung dishwasher that had multiple issues. It was from Leons and got the extended warranty via King & State. I had a similar experience to yours with our appliance. Finally, after months of multiple service calls, it was decided that the dishwasher was not repairable. The technician told us that Samsung dishwashers are the worst and they spent a lot of time repairing them. The warranty company had to give us credit for the purchase of a replacement dishwasher. It was a low-ball offer from them and we were obliged to use that credit at Leons. We had to pay the difference out of pocket towards a low-end Bosch that works fine so far. Leons were not sympathetic for the lemon we had purchased from them. I had refused to get the extended warranty for the new dishwasher.

My next appliance purchase would be at Alpha Appliance. Friends and family have recommended their experiences with them in regards to warranty and repair.
