William E Louisville , KY February 28, 2015 Appliance: Model NOT SURE Dishwasher rack has broken wheels Instead of ordering replacent wheels I opted to order the full complete rack. And as a bonus decided to order the Lower Spray arm. Instillation was simple lift up the lower spray arm, put new one on then slide lower roll rack back into dishwasher. So tedious installation required. Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
