When choosing a dishwasher, think about how you will be using it. What size and configuration do you need the racks to be and are they adjustable? Do you need special cycles or a heated drying option? A Coast Appliances expert can guide you through the available options.
Typically, a dishwasher will last about ten years. But by the end of that time, you may need to pay for regular repairs, so it may be more cost-effective to replace a dishwasher before it stops working altogether.
Unless something is wrong, there should be no need to service your dishwasher. The best service you can give your dishwasher is to keep it clean: clear out any filter or screen it may have and run it on a self-clean cycle once a month. Your trusty product manual will have detailed information on periodic and deep cleaning to keep your dishwasher like new.
