Once you've lived with the convenience of a dishwasher, it's hard to imagine going back to life without one. But this kitchen appliance isn't built to last forever: The average dishwasher lifespan is around 10 years, according to data from Consumer Reports. Replacing a dishwasher isn't cheap, so maintenance matters when it comes to prolonging its life. Here are some effective ways to keep your dishwasher running smoothly and get the most out of your investment.
Turns out there is a right way—and a wrong way—to load a dishwasher. Misloading your dishes can damage spray arms, block detergent flow or overwork the motor, leading to costly repairs or even a replacement.
Resist the urge to cram as many items as possible into your next load of dishes. Overloading uses more energy and water and leads to a less efficient—and less effective—cleaning. You end up using more water and energy in the long run to redo the dishes that your overloaded appliance couldn't handle. You also run the risk of breaking fragile dishes and glasses if items are too close together. Overloading can be hard on your dishwasher over time, leading to repairs or replacement.
Underloading a dishwasher can also hurt your machine's performance. A too-light load can throw off the appliance's spin cycle, leading to a noisy and vibrating load of dishes. Plus, it's a waste of water. Aim for a middle ground and run each load with a dishwasher that's full, but not overflowing.
Myth: You have to rinse your dishes before they go into the dishwasher.
Reality: Today's dishwashers don't require any pre-washing of dirty wares. So skip the rinse—it wastes water and can actually make it harder for your dishwasher to do its job. Modern dishwashers have sensors to detect the soil level of each load, and pre-rinsing hinders this process.
The one exception is big chunks of food. It's always a good idea to scrape those off the plate and into the trash before loading your dishes.
Choosing the “best" dish detergent comes down mostly to personal preference. Options include gel, powder and pods:
Avoid too much of a good thing: Excess detergent can lead to oversudsing (when soap suds spill out the sides of your dishwasher) and leakage. It can also increase the wear and tear on your dishwasher hoses and seals over time.
And what about rinse aids? These products promise to eliminate water spots and speed up drying time. You can experiment with your own dishwasher to see if rinse aid makes a difference. It may be most helpful for people with hard water, as it helps prevent unsightly spotting and mineral deposits on dishes.
If your dishwasher is emitting an unpleasant odor or your dishes aren't coming out as sparkling clean as they once did, a dirty filter could be to blame.
A clogged filter can stress the pump and reduce your machine's cleaning power. Fortunately, cleaning the filter is an easy task to tackle on your own. Aim to do it once every couple of months.
Most dishwasher filters are easy to find at the bottom of the machine beneath the propeller, but check your owner's manual for specific instructions to avoid damaging your unit. Once you remove the filter, rinse it in hot water and scrub with a gentle brush to remove any caked-on debris.
A monthly dishwasher cleaning cycle can help mitigate the grease, limescale and mold that build up over time. Here's how to do it:
However you clean your dishwasher, never combine vinegar with bleach. When these two chemicals come together, they create a hazardous gas that can cause serious health issues.
Your dishwasher's spray arm—the propeller-like part at the bottom of the machine—benefits from a regular cleaning every few months. Cleaning the arm can remove stuck-on food deposits and grease that block the spray nozzles.
To clean the spray arm, carefully remove it from your dishwasher according to the manufacturer's instructions. Use a small brush or toothpick to gently remove gunk from the tiny holes in the arm. For extra dirty jobs, first soak the arm in a 1:1 solution of white vinegar and water to help soften debris before going in with a toothpick.
The gasket around the perimeter of your dishwasher plays an important role in sealing off the dishwasher and preventing leaks. If your unit is leaking, inspect the gasket to make sure it's properly seated. Refer to the owner's manual if you aren't sure where to locate it. You may be able to readjust the gasket on your own if it has simply come out of place. If you notice cracks or tears in the gasket, you may need to purchase a replacement gasket.
As soon as you notice a strange noise, unpleasant smell or drainage issue, take action to find the root of the problem. If one of the tips above doesn't solve the issue, call in the pros for a dishwasher repair. Addressing concerns before they get worse can prolong the life of your dishwasher and put off an expensive replacement.
A little bit of maintenance goes a long way in extending the life of your dishwasher—and it can save you money, water and hassle along the way.
