I had this problem with a Hoover wdm 120, it would wash, and dry, but wouldn't spin. I went through the all the options, motor, motor brushes, clogged pump and pipes, I was at a loss. Finally I spoke to someone who was positive with their answer, "it's the module." I picked up a second-hand one off him for £25 and bingo, the machine spun.
