What usually goes wrong with a dishwasher?

What usually goes wrong with a dishwasher includes several common failures that account for most service calls. First, not draining or standing water at bottom due to drain pump clogged with food particles, glass, and grease or failed drain pump at 20 to 60 dollars, or clogged air gap or garbage disposal connection, accounting for about 30 percent of dishwasher service calls. Second, not cleaning dishes well or leaving food particles due to spray arm clogged with food that blocks holes, or filter clogged with debris that needs monthly cleaning under lower rack, or low water temperature below 120 degrees. Third, not filling with water due to inlet valve clogged with sediment from hard water at 15 to 30 dollars or float switch stuck in up position. Fourth, leaking water onto floor due to door gasket worn after 5 to 8 years, loose hose clamp, or overfilling due to faulty inlet valve. Fifth, not drying dishes due to heating element failed at 30 to 60 dollars or rinse aid empty. Sixth, loud noise or grinding during operation due to drain pump or wash pump motor failing with food stuck in impeller. Seventh, door not latching due to door latch failure at 20 to 35 dollars. Eighth, control board failure from power surge causing blank display. To prevent most dishwasher problems, clean filter monthly, scrape plates before loading, use rinse aid, and run Affresh cleaning cycle monthly.
