What's the most common problem with a whirlpool dishwasher?

The most common problem with a Whirlpool dishwasher is not cleaning properly or leaving food residue on dishes, followed by not draining and leaking. The cleaning issue is usually caused by clogged filter that traps food particles at bottom of tub under spray arm and needs cleaning every 30 days, clogged spray arm holes that get blocked with food and mineral scale, and low water temperature below 120 degrees that prevents detergent from dissolving. This accounts for nearly 35 percent of service calls. 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 that costs 100 to 200 dollars. 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. Fifth is not drying dishes due to failed heating element or rinse aid empty. Sixth is noisy operation from food trapped in pump. To prevent most common Whirlpool dishwasher problems, clean filter monthly by twisting counterclockwise and rinsing, 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 like Cascade Platinum.
