Hi,
I've got a Whirlpool WFS1071BW front loader, and it won't spin.
On the spin cycle, it drains for a while, spins slowly drains some more, but then stops before it does the actual spinning. Note, it complete a gentle spin cycle, just not the normal one.
On a normal wash, it gets to the spin cycle and stops (doesn't spin)
Any suggestions?

There is a solenoid coil that controls the spin cycle. You need to test it with an ohm meter to see if it's bad. Look at: http://spares.alliedappliance.com.au/ for a picture of it (Item 612141001). Don't buy from this company unless you are in Australia as the voltage won't match. You can buy a coil at many HVAC or appliance parts stores for about $5.00 if it's a generic coil.
