Assuming you are talking about a dishwasher that is not new, the answer to this question depends on many factors. One of the most important factors is the cost of the repair. If the repair will cost more than half of the price of a new dishwasher, it is probably not worth fixing. Another factor to consider is how old the dishwasher is. A dishwasher that is more than 10 years old may not be worth repairing because it may not last much longer even after being repaired. Finally, consider how often you use your dishwasher. If you only use it once a week, it may not be worth repairing because it will take a long time to recoup the cost of the repair through savings on your water and electricity bills.
