Fast Spin Washers
I remember reading in Which magazine about fast spin machines. I think it was in the early 80,s. Which said, "there might, or could be reliability problems with fast spin machines.
If you go back in time, most machines would spin below 800rpm, and most machines would last a good few years without breaking down, compared to modern day machines.
I know Miele are made so well they don,t seem to have any breakdowns. My Mums Miele machine is about 10 years old now, 1200 rpm, washes nearly every day, and never had any problems.
