Cleaning a dishwasher? Sounds ironic, doesn’t it? After all, its job is to clean. Yet, over time, dishwashers can become a breeding ground for bacteria, mold, and grime. Whether you use your dishwasher once a week or multiple times a day, keeping it in top shape is key to ensuring it runs efficiently, extends its lifespan, and maintains that fresh, clean smell. If you’re not regularly cleaning your dishwasher, the results can include dishes that don’t get fully clean, foul odors, and even mechanical failures. So, let’s walk through the complete process of cleaning your dishwasher from top to bottom.
Why Is It Important to Clean Your Dishwasher?
Before diving into the “how,” let’s talk about why you should bother with all this maintenance. Dishwashers, like any other appliance, build up mineral deposits, grease, food particles, and soap scum. These residues can clog spray arms, filters, and drain hoses, leading to poor performance or damage. Regular cleaning can:
- Ensure better performance: Clean dishes start with a clean dishwasher. Clogged spray arms and filters can prevent water from reaching all areas of your plates and cups.
- Extend the lifespan of your dishwasher: Like all appliances, if well-maintained, your dishwasher will last longer and perform more efficiently.
- Prevent unpleasant odors: The presence of food particles in the dishwasher can lead to mold growth and bad smells.
- Maintain energy efficiency: If the dishwasher is clogged, it uses more energy to complete a cycle, which can increase your utility bills.
How to Clean a Dishwasher: Step-by-Step Guide
1. Clear out the Dishwasher
Before you start, make sure to remove all dishes and utensils. It’s also a good idea to pull out the racks, as some parts may need a deeper clean.
2. Check and Clean the Drain
The first area to focus on is the drain. A clogged drain can cause water to pool at the bottom of the dishwasher, leading to unpleasant odors and poor cleaning results.
- Locate the drain (usually at the bottom of the dishwasher, near the center).
- Remove any debris: Check for food particles or other obstructions.
- Clean with a soft brush: You can use an old toothbrush to scrub the area and remove any stubborn grime.
3. Clean the Filters
Many dishwashers come with a filter that captures food particles to prevent them from circulating back onto your dishes.
- Remove the filter: This can usually be done by twisting or pulling it out.
- Wash the filter under warm water: If it’s clogged with grease, soak it in a mixture of warm water and dish soap for 15 minutes, then scrub with a soft brush.
- Reinstall the filter: Once clean, place it back in the dishwasher.
4. Wipe the Door and Gasket
Dishwasher doors and gaskets (the rubber seals around the door) can accumulate food particles, soap scum, and water stains.
- Wipe the door: Use a damp cloth with mild dish soap to wipe down the interior of the door.
- Clean the gasket: Pay special attention to the gasket, as mold and mildew can thrive here. You can use a toothbrush or small brush to clean around the edges. If you notice mold or mildew, use a mixture of equal parts vinegar and water to disinfect.
5. Clean the Spray Arms
Spray arms are essential for water distribution during the cycle. If these are clogged, your dishwasher won’t clean effectively.
- Remove the spray arms (usually, you can twist them off or unscrew them).
- Inspect the holes for any food particles or mineral buildup.
- Clean the spray arms by rinsing them under water and poking through any blockages with a toothpick or small tool.
6. Run a Cleaning Cycle
Once you’ve cleaned out the visible areas, it’s time for a deep clean.
- Use vinegar: Place a dishwasher-safe cup filled with white vinegar on the top rack of the dishwasher. Run a hot water cycle. The vinegar will help remove mineral buildup, grease, and soap scum.
- Use baking soda: After the vinegar cycle, sprinkle a cup of baking soda on the bottom of the dishwasher. Run another short cycle on the hottest setting. This will help eliminate odors and further clean the interior.
7. Tackle Stubborn Odors
If odors persist, consider running a cycle with a dishwasher cleaner (like affresh or similar products). These are specially formulated to break down stubborn residues and help freshen your dishwasher.
8. Dry and Reassemble
Once you’ve finished the cleaning cycles, wipe down the interior with a dry towel. Reassemble the racks, spray arms, and filters, and your dishwasher should be fresh and ready to go.
Additional Tips for Maintenance
- Run the dishwasher regularly: Even if it’s just with water. Running it once every couple of weeks without dishes helps prevent water deposits and mold growth.
- Use the right detergent: Overuse of detergent can lead to buildup, and using low-quality detergent can cause soap scum. Opt for high-quality, eco-friendly detergents that are gentle on the machine.
- Don’t overload it: Overloading can prevent the spray arms from working effectively, leading to dirty dishes and increased wear on the dishwasher.
- Leave the door ajar: After a cycle, leave the dishwasher door slightly open for a while to allow moisture to escape. This helps prevent the growth of mold and mildew.
Common Problems and How to Fix Them
Even with the best of care, sometimes things go awry. Here are a few common issues and their solutions:
- Water not draining: This could be due to a clogged drain or filter. Check for obstructions and clean accordingly.
- Dishes still dirty after a cycle: If your dishes aren’t coming out clean, it could be a spray arm issue, or the dishwasher may not be using enough water. Clean the spray arms and check the water inlet valve.
- Foul odors: If your dishwasher stinks, it could be due to trapped food in the drain or buildup in the filter. A cleaning cycle with vinegar and baking soda should do the trick.
