Ordered the OEM replacement of the upper rack height adjuster for our Kitchenaid dishwasher from AppliancePartsPros. The installation video was outstanding for the new parts. I just had to realize the removal of the old part was different from the video... however... it was not a biggy. Total job was less than 30 minutes from start to finish. The costs of my parts and shipping was around $55.00. The appliance repairman quoted my wife $257.00 plus tax.
