We bought a Samsung washer and a Samsung dryer 6 months ago. Top of the line. I've never had a front loader before, didn't want one, but here were are.
Every month or so the bottom filter sensor says that its blocked. So you have a machine full of water that can't drain, and the lowest point in the machine saying there's a blockage. There's not. There never is. It's an optical sensor that gets dirty. The thing is, at that point, the only way to drain the machine and clean the sensor is by undoing a little 3mm ID hose and pulling the stopper out that they have helpfully supplied. You get water everywhere. Why on earth you would use an optical sensor in a machine built to handle dirty water, small solids, and is known to accumulate soap and detergent scum is absolutely beyond me.
To remedy that, I have a 12v laptop adapter + a 12v bilge pump for a boat and some spare drain hose, put the bilge pump in a baking tray, let the bilge pump take care of sending the water to the shower or sink, and drain the machine via the tiny hose. Clean off the sensor with water from a spray bottle, maybe a little vinegar or glass cleaner. Replace everything, and start the load.
Well over $1,500 of machine and in my mind it's a piece of crap. I wished for a small commercial top loader. It didn't match the nice theme. Now we have a Rube Goldberg disaster mitigation plan that gets actioned quite frequently.
Also, booking a Samsung service tech is hard.
