Tim J Grand Island , NE October 27, 2014 Appliance: Model 665. 13763K600 Loud grinding noises I installed a new circulation pump and motor assembly by myself after watching the video at AppliancePartsPros.Com. The install is not difficult if you can follow directions and the video made the job less intimidating. It took me over two hours but I'm the kind of guy that takes it slow so I don't have to do things twice. The washer runs like a new one now and I have been enjoying a little self satisfaction. Thanks AppliancePartsPros. 12 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 2+ hours
