I have a whirlpool AWM822 Washing Machine. The machine washes fine, aggetates fine and drains fine, though it will not spin! I initially thought it may be the load so I tried both a half load and no load at all. Both times the machine emptied fine but never spun. I have inspected the filter 3 times and removed the large drain nozel (the one attached to the drum) to check for blockages though there is none. Can anyone help? I am assuming it may be the brushes though would be grateful of any advice before attempting to change them.
