Product review (4 stars): Arrived broken
Keep your old part until it arrives!
Mine was poorly packed and the knob shaft was snapped off at the base.
Luckily I had the old shaft so I popped open the case and swapped the parts.
If you do this be slow and careful not to lose the tiny spring and pin that provide that satisfying "click" when you turn the knob.

Part works fine now and I am back to washing laundry.
