Is it worth fixing a KitchenAid dishwasher?

Is it worth fixing a KitchenAid dishwasher depends on age, type of failure, and cost of repair versus replacement. For minor repairs like drain pump replacement costing 100 to 200 dollars including pump at 30 to 70 dollars that fixes not draining and standing water at bottom, inlet valve replacement at 80 to 150 dollars including valve at 20 to 40 dollars that fixes not filling, door latch replacement at 80 to 150 dollars including latch at 30 to 50 dollars that fixes door not closing, and spray arm replacement at 50 to 120 dollars, repair is usually worth it if dishwasher is less than 7 years old and otherwise cleaning well, as new KitchenAid dishwasher costs 1,000 to 1,600 dollars. For major repairs like wash motor and pump assembly replacement costing 300 to 500 dollars including motor at 150 to 250 dollars, and control board replacement costing 250 to 400 dollars including board at 150 to 250 dollars, it is only worth it if dishwasher is premium model like KDPM804KPS costing 1,200 to 1,600 dollars new and less than 5 years old, otherwise replacement is better as other components like heating element will soon fail. If KitchenAid dishwasher is over 9 years old and needs any repair over 250 dollars, replacement is more economical as average lifespan is 9 to 12 years and new models save water. If repair exceeds 50 percent of replacement cost, buy new.
