Chris G Houston , TX January 08, 2019 Appliance: Model WHIRLPOOL DISHWASHER Upper dishrack wheel broken You Tube video. Simple 10 minute fix. Biggest issue was removing the rail stops, these may be 'stuck' with water limescale. Use silicone spray or wd 40 as lube and pliers to gently squeeze in the top retainer.
