Product review (5 stars): My clothes are clean again
There is a filter on this machine that prevents debris big enough from damaging the motor from getting in, this did not prevent ice from entering and damaging the paddle/impeller one frozen morning.  I tried repairing the paddle but it seems as soon as the motor heats up it tends to damage itself in unknown ways.
I ordered this and installation could not be easier.  Note: there are holes for more screws but I just used the 3 main screw holes, it fits in with the flat top plug end tilted slightly forward. That gives you a good fit/seal at the base of the impeller housing.
It didn't take long and it was good to go.  The only part that hurt was the $65 price, which I thought is a bit high for today's standards, also compared to other models, but it sure beats a thousand or two in replacement costs.
