Your dishwasher works hard every day to clean your dishes, but how often do you take care of it? Here are some dishwasher maintenance tips from our kitchen experts. From deep cleaning to proper loading, there are a few helpful tricks that can prevent wear and tear, boost cleaning power, and extend your model’s lifespan by years. Learn how to keep your dishwasher in tip-top shape with just a few minor changes to your habits.
Cleaning Basics
Believe it or not, keeping your dishwasher clean helps it run better and last longer. Debris can build up inside unit over time, reducing spray pressure, draining performance, and leaving your dishwasher with an odor. Take a few minutes after heavy use or once a month to:
- Clean out the filter. Remove any large debris trapped after running the dishwasher.
- Wipe down the door gasket and edges. Cleaning off food particles will help prevent dirt from building up inside.
- Remove stuck debris from the spray arms so water can pass through when running.
- Check the bottom of the dishwasher tub for leftover scraps.
- Run a dishwasher-safe cleansing pod when you notice leftover residue orFilm.
If you keep these areas clean, you can protect the dishwasher pump and heating element from working too hard to clean dishes and remove excess residue.
Dishwasher Maintenance Tips #1: Loading Dos and Don’ts
You should also consider how you load your dishwasher to improve efficiency. Did you know that overcrowding your dishwasher can impact how water flows through the unit? Large items can block spray arms while improper placement may trap food debris and prevent detergent from reaching every dish. Here are a few loading tips:
- Load larger items like cutting boards and baking sheets along the sides or back of the rack.
- Angle cups and bowls so that water can run off instead of pooling.
- Don’t nest utensils or bowls together.
- Ensure there is ample space between dishes and the spray arms can rotate.
- Don’t block the detergent dispenser.
Loading dishes properly helps your dishwasher do its job and may prevent you from running extra cycles. Fewer cycles mean your appliance uses less energy and experience less wear over time.
Dishwasher Maintenance Tips #2: Monthly Maintenance
You should also perform a quick check-up on your dishwasher once a month. With daily use (and depending on the hardness of your water), minerals can build up inside your dishwasher, leaving you with decreased performance over time. Other components to check monthly include seals, racks, tubes, and any other visible connection.
Look for signs of cracking, rust, and leaks. If you catch these problems early, you may be able to prevent further damage to your dishwasher and avoid mildewing cabinets or corrosion of electrical parts.
Dishwasher Maintenance Tips #3: Detergent Usage
Not only does the right detergent make your dishes sparkle, but it also helps your machine run smoothly. Using too much detergent can leave a build-up on dishes while too little could mean your dishwasher starts additional rinse cycles. Find the right balance and your dishwasher will thank you.
You should also use rinse aid in your dishwasher. Rinse aid improves efficiency by limiting the amount of water spots on your glassware and dishwasher’s interior. Think of it as preventing hard water build-up inside your dishwasher.
Dishwasher Maintenance Tips #4: Water Hardness
Hard water affects your dishwasher’s cleaning power and performance. Over time, mineral deposits from hard water can build upon your dishwasher’s heating element, spray arms, and inside walls. The build-up reduces efficiency and can cause parts to wear out much quicker.
If you live in an area with hard water, try using a water softener or dishwasher cleaning product to reduce the amount of white chalky build-up you find in your machine. The fewer deposits, the quieter your dishwasher will run.
Dishwasher Maintenance Tips #5: Hose and Seal Care
Tiny parts like seals and tubing play a massive role in preventing leaks. Checking your dishwasher’s seals and hoses for wear and tear can prevent future damage to counter floors and cabinets.
Consult your manual on how to best check these components. Typically, you’re looking for swollen seals, brittle hoses, loose clamps, and water buildup around connection points. Door seals should be replaced when they start to lose flexibility. Taking care of these areas reduces the risk of mold growing in your dishwasher.
Dishwasher Maintenance Tips #6: Efficient Dishwasher Use
How often you run your dishwasher matters too. Running your dishwasher with a full load is great for the environment and saves you money, but do you know when it’s too much? Loading your dishwasher too full can cause poor circulation and decrease water pressure. Your dishwasher must work harder to clean your dishes which could lead to additional strain on your machine.
You should also avoid using higher temperatures than recommended. High heat is only necessary if you need to sanitize dishes. Allowing dishes to cool down before loading them in your dishwasher may help reduce wear on seals and dish racks.
Dishwasher Maintenance Tips #7: Advanced Warning
If you pay close attention to your dishwasher, you’ll likely notice changes in performance before it breaks down. Hearing odd sounds, finding water at the end of a cycle, noticing a smell, or wanting dishes to come out clean are telltale signs that something may need serviced.
The following table highlights common dishwasher warning signs, their causes, and potential solutions:
| Warning Sign | Possible Cause | Solution | Frequency to Check |
| Odd noises | Loose parts or debris | Check and tighten components; clean filter | As needed |
| Water left after cycle | Clogged drain filter | Clean the filter and inspect drain hose | Monthly |
| Unpleasant odor | Food debris or mold | Run a cleaning cycle with vinegar or a dishwasher cleaner | Monthly |
| Dirty dishes post-clean | Blocked spray arms | Unclog spray arms and ensure proper loading | Monthly |
By addressing issues promptly, you can prevent major breakdowns and extend the life of your dishwasher.
The sooner you can identify a problem, the sooner you can stop something larger from occurring. Maybe your filter is blocked and easy to clear or your dishwasher is having repeated drainage issues. Minor issues may be able to be solved quickly.
Bonus Dishwasher Maintenance Tips: Create a Schedule
No one wants to deep clean their dishwasher more than they have to. Instead, create a monthly routine that you can manage. By cleaning your dishwasher monthly, inspecting seals and filters, loading carefully, and using the correct amount of detergent, you can improve your dishwasher’s lifespan and efficiency.
Pick a day every month to check your filter, seals, spray arms, and visible tubing. Once a quarter, you can deep clean your dishwasher. Proper care your dishwasher now will ensure it runs smoothly for years to come.
