What are signs your dishwasher needs to be replaced?

What are signs your dishwasher needs to be replaced include several indicators that repair cost exceeds value and average lifespan reached. First, age over 9 to 10 years as average lifespan of dishwashers is 9 to 12 years, if your dishwasher is over 10 years old and needs repair over 200 dollars, replacement is more economical as other components like wash pump and control board will soon fail and new Energy Star models save water. Second, standing water at bottom that returns after cleaning filter and drain pump, indicating failed drain pump and wash pump motor that costs 250 to 400 dollars to replace, over 50 percent of new dishwasher cost at 500 to 900 dollars. Third, not cleaning dishes well even after cleaning filter, spray arms, and using rinse aid, indicating weak wash pump motor that no longer provides pressure. Fourth, leaking water onto floor from door gasket, tub crack, or hose that causes floor damage, door gasket costs 30 to 60 dollars but tub crack is not repairable. Fifth, rust on racks and inside tub that causes dishes to stain and indicates tub corrosion. Sixth, loud grinding or banging noise during operation indicating failing wash motor. Seventh, control panel blank or buttons not responding after hard reset, indicating control board failure at 200 to 350 dollars. Eighth, rising energy and water bills due to old inefficient model using more water than new Energy Star that uses 3 gallons per cycle.
