A homeowner turned to Reddit for advice on a dishwasher dilemma — spend $300 on replacement racks for a machine that is more than 20 years old, or pay $900 for a new model and hope the lower water and electricity use makes the extra cost worthwhile.
Here's what to know
In a Reddit thread, the original poster said, "I have to buy new racks for 300 bucks, or I can buy a new dishwasher for 900 bucks. What is more economical considering electricity and water prices?" They added that "everything is functioning perfectly, the only problem is that some racks are a little rusty."
Most commenters favored repairing the existing dishwasher rather than replacing it, mainly because the appliance is still working well.
One commenter captured that view in six words: "If it ain't broke don't fix it." The same commenter advised the owner to "buy new racks and start setting aside money for when it eventually dies."
Several commenters also questioned whether $300 is really the price the owner needs to pay for racks. Suggestions included using a rack repair kit such as ReRack or Sugru if the rust is minor, checking eBay, and looking for compatible Whirlpool dishwasher racks. Another commenter said they had bought used racks for about $80 shipped and kept a 30-year-old machine running.
There was one clear dissenting view: "Buy a new dishwasher. It will be more economical due to less water and energy cost." Still, the discussion pushed back on making that assumption without first checking actual usage and utility bills.

More background
A new dishwasher may use less water and electricity, but that alone doesn't mean it will be the cheaper option over a shorter span, such as five years.
The original poster also said they did not want to "disassemble my entire kitchen by buying a new one," which points to costs beyond the purchase price. With built-in appliances, installation can mean extra labor, plumbing surprises, and general hassle before utility savings begin to show.
Waste also factors in. Replacing a working machine because of worn racks means discarding an appliance that may still have years of useful life left. Repairing a functional unit can be the lower-impact choice, provided the fix is reasonably priced, and the dishwasher is still cleaning effectively.
What can be done?
Before making a major purchase, the thread suggested a few practical steps. First, verify the full model number before ordering parts, since one commenter noted the posted model number appeared incomplete. That can make a major difference when searching for compatible racks.
Second, compare more than retail prices alone. Used racks or rack repair kits may lower the repair bill substantially, which can quickly change the math.
Third, calculate the break-even point based on your own household habits. One commenter distilled the issue into its simplest form: "At those prices, replacing it costs $600 more than replacing the racks. To earn that back in five years, the new one would need to save $120 a year in water and electricity. I'd work out that number from your actual bills and cycle frequency before counting on the savings. Also double-check the model number on the door before ordering racks."
