Open the dishwasher door to pull out the upper rack after the cycle is finished. Remove all items from the upper rack.
Pull the side pins outward on the left and right rack edges near the front to pop them loose from the rack.
Pull the pins outward using pliers, if necessary, to disengage the parts from the rack sides if the pins are difficult to remove. Months or years of running hot water in the appliance may cause the pins to become stuck, as the plastic parts repeatedly soften slightly and harden after cooling.
Rotate the pins downward to unlock the end caps, which now snap open.
Pull the rack-pin and end-cap assemblies on the left and the right off the rack from the front.
