Gunnar H Cincinnati , OH January 14, 2024 Appliance: Whirlpool Undercounter Dishwasher GU2475XTVB1 Whirlpool Dishwasher Gu2475xtvb1: Lower rack falling apart. How to replace Dishwasher Lower Dishrack. Replaced the entire lower dishrack with a new rack. Swapping the wheels and clips was simple. The only problem I encountered was the new rack did not come with the fold-down "tine row" used in the rear part of the rack. That part needed to be ordered separately.
