Dishwasher Cleaning & Maintenance Tips

Your dishwasher puts in a ton of work throughout the year, saving countless hours you’d otherwise spend hand washing dishes. Of course, like most home appliances, dishwashers need routine cleaning and maintenance to keep them running their best.

If you’d rather not go back to washing every plate, bowl, and spoon by hand, read on. This guide will help you get the most out of your dishwasher, regardless of brand, make, or model.

Why is dishwasher cleaning and maintenance important?

Regularly cleaning and maintaining your dishwasher is critical. If you don’t keep up with it, you might notice specks on your dinnerware or strange odors coming from the machine. It won’t clean dishes nearly as well if it’s not clean itself.

Dishwasher maintenance and basic cleaning can also help your dishwasher last longer. According to Consumer Reports, dishwashers should last about 10 years. However, they also note nearly one in four dishwashers had issues within the first few years of ownership. That’s roughly 25% of dishwashers breaking down before the five-year mark.

Naturally, proper maintenance and careful cleaning reduce these risks, but you’re not alone in worrying about your home appliances failing. That’s why we offer home warranty coverage on dishwashers in addition to garbage disposals, refrigerators, stoves, and more.



Should you rinse dishes before loading a dishwasher?

Yes! Proactively rinsing dishes before adding them to a dishwasher is better for the appliance. If you don’t rinse dishes beforehand, particles and debris may get stuck in the moving parts of your dishwasher.

Rinsing dishes in advance also helps ensure they’re completely clean at the end of each wash cycle.

Note that you should never overload your dishwasher. An overloaded dishwasher won’t clean as well as one that’s loaded correctly. Too much clutter keeps water and soap from reaching all surfaces on all dishes. This means you might need to wash them again the next time you use them.

What maintenance does a dishwasher need?

Like most home appliances, dishwashers require routine maintenance. Fortunately, dishwasher upkeep is pretty easy. In fact, most homeowners can manage it themselves.

1. Filter Cleaning

Many dishwashers have a built-in filter to catch food and debris that may otherwise clog your plumbing. These filters are typically found beneath the bottom spray arm.

Every dishwasher is different, and filters vary among different models. Typically, the filter looks like a mesh screen that can be taken out, shaken off, and rinsed.

In select appliances, the filter can look like a grate above the drain hole. For more modern dishwashers, there may be an additional mechanism to catch food particles. These can often be turned/twisted and lifted out to remove for cleaning.

Once removed, rinse the dishwasher filter in your sink, using regular dish detergent to clean as needed. Any large food debris can be removed from your drain stopper and thrown in the trash. If you have one, you can also send it down your garbage disposal.

If you’re unsure of where to find the dishwasher filter, carefully check around where the water drains. You can also reference the owner’s manual for your dishwasher if you’re still having trouble pinpointing the filter.

2. Routine Cycles

Dishwashers need to be run routinely in order to perform their best. Make a point of running your dishwasher once a week (or more) to keep things working as they should.

This is important for the health of the motor, seals, and other dishwasher parts.

3. Interior & Exterior Cleaning

Believe it or not, dishwashers still require regular cleaning. Some dishwashers might have a lifetime of buildup affecting performance. This could be a mix between mineral deposits from hard tap water or grime from food particles.

You should clean your dishwasher at least once per month. This will fight the buildup of mold, bacteria, and other nasty stuff that can lead to odors or other issues.

While plenty of dishwasher cleaners are available at your local grocery store, vinegar is a great alternative. It’s completely safe to use, too! As a result, you can run a wash cycle with vinegar to effortlessly clean the machine’s interior.

To run a load that will help rinse away heavy build up, follow these simple steps:

  1. Fill a bowl with vinegar and place it on the top shelf in the dishwasher.
  2. Pour some of the vinegar in the bottom of the dishwasher, as well.
  3. Run your dishwasher empty (i.e., don’t put in any other dishes).
  4. Wait for the cycle to complete.
  5. Wipe down the dishwasher’s interior using a clean cloth.

Be sure to take this opportunity to wipe down any gaskets, as well as the door and exterior of the dishwasher.

If you’re using a dedicated dishwasher cleaner, follow the instructions on the package. Cleaning steps may vary depending on the product.

Do you need to clean the spray arms?

If your home taps into hard water, there may be mineral buildup around the spinning arms and other moving parts. This can also happen over time from food particles.

Soak the arms in vinegar and use a pipe cleaner to scrub the holes if there’s especially bad mineral buildup.

You may find that there is a mechanical issue with your spray arms and need service. When you have a home warranty plan, we’ll connect you with a service technician to sort out a fix.



What are the signs your dishwasher is dying?

Watch out for these common problems and signs that your dishwasher is going out:

  • Dishes aren’t coming clean.
  • Dishes aren’t hot after a completed cycle.
  • It’s making strange, funny, or odd noises.
  • Rust or corrosion is present inside or outside the machine.
  • The door doesn’t close all the way or won’t latch properly.
  • There are cracks inside the dishwasher.
  • Water is leaking from the dishwasher.
  • Water refuses to drain from the unit.

Most manufacturers offer a limited one-year warranty for dishwashers, though this varies from brand to brand and model to model. If you’re having issues with a dishwasher, you may be covered under your home warranty.
