If you put anything remotely bulky in there, say a mattress pad with anything else (a towel or sheet), even on the speed cycle the washer will have a hard time “balancing” and will cycle through sensing, spinning unsuccessfully and then refilling. Over and over and over. I’ve literally been sitting at my house waiting hours to leave on a road trip because it wouldn’t just spin. Finally had to force it to stop, pull everything out sopping wet and spin one thing at a time. I hate this washer.
