What are some common problems with Whirlpool dishwashers?

Common problems with Whirlpool dishwashers include cleaning failures, draining issues, and leaking. The most frequent problem is not cleaning properly or leaving food residue on dishes, accounting for nearly 35 percent of service calls, caused by clogged filter at bottom that traps food and needs cleaning every 30 days, clogged spray arm holes blocked with food and mineral scale, and low water temperature below 120 degrees that prevents detergent from dissolving. Second most common is dishwasher not draining with water standing in bottom at end of cycle, displaying F9E1 or E2 error, due to clogged filter, clogged drain hose or air gap at sink, or failed drain pump costing 30 to 60 dollars for part. Third is dishwasher not starting or not filling with no water entering, due to failed water inlet valve, door latch not engaging, or control lock activated. Fourth is leaking from door or underneath due to worn door gasket, loose hose clamp, or cracked tub or float stuck. Fifth is not drying dishes due to failed heating element, rinse aid empty, or vent not opening. Sixth is noisy operation from food trapped in pump or chopper assembly. Seventh is control board failure from moisture or power surge. To prevent most Whirlpool dishwasher problems, clean filter monthly, clean spray arms every 3 months, run hot water at sink before starting to ensure 120 degree water, use rinse aid, and use high-quality detergent.
