How to Extend the Life of Your Dishwasher

The average dishwasher lasts about 10 years, but with proper care, many models can run efficiently for 12 to 15 years. Neglecting basic maintenance is the most common reason dishwashers fail prematurely. Here are straightforward steps you can take to protect your investment and avoid unnecessary repair bills.

Clean the Filter Regularly

Most modern dishwashers have a removable filter at the bottom of the tub. Food particles, grease, and debris collect here over time and restrict water flow. Remove the filter every two to four weeks, rinse it under warm water, and use a soft brush to clear any stubborn residue. A clogged filter forces the pump to work harder and leads to poor cleaning performance.

Inspect and Clean the Spray Arms

The spray arms have small holes that distribute water throughout the wash cycle. These holes can become blocked with mineral deposits or food particles. Remove the spray arms periodically and use a toothpick or thin wire to clear each hole. Rinse them thoroughly before reinstalling.

Run Hot Water Before Starting a Cycle

Before you press start, turn on the kitchen faucet and let the hot water run until it reaches its highest temperature. This ensures the dishwasher fills with hot water from the very beginning of the cycle, which improves cleaning performance and helps dissolve detergent properly.

Use the Right Detergent and Amount

More detergent does not mean cleaner dishes. Excess detergent leaves residue on your dishes and inside the machine, and it can clog spray arms and the drain. Follow the manufacturer’s recommendations for detergent type and quantity. If you have hard water in Pasadena, consider using a rinse aid to prevent mineral buildup.

Keep the Door Gasket Clean

The rubber gasket around the door traps moisture, food particles, and mildew. Wipe it down with a damp cloth and mild soap every week or two. A deteriorating gasket allows water to leak during cycles, which can damage your flooring and cabinetry over time.

Run a Monthly Cleaning Cycle

Once a month, run an empty cycle on the hottest setting with a cup of white vinegar placed upright on the top rack. This dissolves grease, removes odors, and clears mineral deposits from the interior. Some manufacturers also sell dishwasher cleaning tablets designed for this purpose.

Load Dishes Properly

Overloading blocks water circulation and leads to poorly cleaned dishes, which tempts you to run extra cycles. Follow the loading guidelines in your owner’s manual. Avoid nesting bowls and make sure nothing obstructs the spray arms.

Schedule Professional Maintenance

Even with diligent home care, it pays to have a professional inspect your dishwasher every few years. A technician can check the motor, pump seals, water inlet valve, and electrical connections for early signs of wear.
