A dishwasher is one of the most convenient appliances in any modern kitchen. But did you know that how you use it could dramatically shorten its lifespan? Many homeowners unknowingly make mistakes that lead to costly repairs or even complete appliance failure long before it should happen.
To help you protect your investment and avoid unnecessary expenses, we’ve compiled a list of the 7 most common mistakes that can reduce the lifespan of your dishwasher — and what to do instead.
While it’s tempting to pack as many dishes as possible into one cycle to save time and water, overloading your dishwasher can restrict water flow and prevent effective cleaning. It also puts extra strain on the machine’s components, especially the spray arms and pump.
What to Do Instead:
Load your dishwasher according to the manufacturer’s recommendations. Make sure that water can reach every dish, and avoid stacking items too tightly.
Placing dishes in the wrong positions or at awkward angles prevents the spray arms from cleaning properly. Sharp utensils pointing upwards can even damage the interior or cause injury when unloading.
What to Do Instead:
Place plates and large dishes on the bottom rack.
Glasses and lighter items should go on the top rack.
Utensils should be loaded with handles down (except sharp knives, which should be handled carefully).
A clogged filter restricts water circulation, reducing cleaning efficiency and placing extra strain on the pump. Over time, this can cause significant wear and tear on your dishwasher.
What to Do Instead:
Clean the filter at least once a month. If you use your dishwasher daily, check it even more frequently. A clean filter helps ensure your dishes come out spotless and keeps your appliance running smoothly.
Using too much detergent or the wrong type can lead to residue buildup inside the dishwasher and on your dishes. This buildup can clog essential components and affect the performance of the spray arms and sensors.
What to Do Instead:
Always use a detergent recommended by your dishwasher manufacturer. Consider using high-quality detergent pods or tablets for consistent results.
Many homeowners ignore early warning signs that something is wrong. Unusual noises or flashing error codes are often indicators of minor issues that, if left unresolved, can lead to major repairs or failure.
What to Do Instead:
Read your appliance’s manual to understand common error codes. If you hear unusual sounds, call a certified appliance technician before the problem worsens.
Just like any other appliance, your dishwasher requires regular maintenance. Skipping maintenance leads to faster wear and shortens the appliance’s lifespan.
What to Do Instead:
Inspect and clean the spray arms periodically.
Wipe down the door gasket to prevent mold and ensure a tight seal.
Run a monthly cleaning cycle using dishwasher cleaner or a mixture of white vinegar and baking soda.
Running the dishwasher for small loads wastes water, electricity, and adds unnecessary wear to the appliance’s components.
What to Do Instead:
Wait until the dishwasher is fully loaded before running a cycle. Use the energy-saving or eco-mode whenever possible to reduce wear on the system.
Your dishwasher is designed to last up to 10 years or more with proper care. By avoiding these common mistakes and performing regular maintenance, you can extend its lifespan, save on costly repairs, and ensure it works efficiently for years to come.
