The Ultimate Buying Guide for Your 18-Inch Dishwasher
An 18-inch dishwasher is a fantastic choice for smaller kitchens, apartments, or homes where you don’t generate a massive amount of dirty dishes every day. These compact models save space without sacrificing cleaning power. But how do you pick the best one? Follow this guide to make a smart purchase.
Key Features to Look For
When shopping, look closely at what the dishwasher can actually do. These features make your life easier.
Cleaning Power and Performance
- Spray Arms: More spray arms mean better water coverage. Look for at least two—one on the bottom and one in the middle. Some high-end models add a third arm at the top.
- Drying System: How does the dishwasher dry your dishes? Heated dry uses a heating element, which works well but uses more energy. Condensation drying uses the heat from the final rinse to evaporate water naturally. This is energy-efficient.
- Wash Cycles: A good dishwasher offers options. Look for Heavy, Normal, Quick, and Eco modes. Extra features like a sanitize cycle are great for baby bottles or germ-conscious users.
Capacity and Racking
Even though it’s small, capacity matters. Check the included racks.
- Adjustable Racks: Can you move the height of the upper rack? This lets you fit tall wine glasses or large plates easily.
- Silverware Basket: Does the basket hold utensils securely? Some newer models have a third, shallow rack at the very top for flatware, which frees up space below.
Important Materials That Matter
The materials inside the dishwasher affect how long it lasts and how quiet it operates.
Tub Material
The tub is the main body inside the dishwasher.
- Stainless Steel Tub: This is the gold standard. Stainless steel lasts longer, resists staining, and helps keep the noise level down because it absorbs sound better.
- Plastic Tub: These tubs are usually cheaper upfront. However, they do not hold heat as well, which can lead to less effective drying, and they might stain over time.
Racks and Coated Components
The racks must withstand high heat and moisture daily.
- Look for racks coated in durable nylon or vinyl. These coatings prevent rust and protect your dishes from scratching. Check the quality of the wheels on the racks too; they should glide smoothly.
Factors That Improve or Reduce Quality
These details separate a basic model from a premium one.
Noise Level (dBA)
This is crucial, especially in open-concept living spaces. Noise is measured in decibels (dBA).
- Quiet Quality: Anything under 48 dBA is considered very quiet. If you run your dishwasher while watching TV, aim for the low 40s.
- Noise Reduction: Quality models use better insulation, solid door construction, and advanced motors to keep the volume down.
Energy Efficiency and Water Use
Check the EnergyGuide label. Efficient models use less water per cycle. Modern 18-inch dishwashers use surprisingly little water, often just 3 to 4 gallons per full load.
User Experience and Use Cases
Think about *how* you will use this dishwasher.
Ideal Use Cases
- Small Families or Couples: If you eat most meals out or only have two people in the house, an 18-inch model is perfect. It prevents you from running a large, half-empty machine.
- Secondary Kitchens/Wet Bars: They fit well in basement bars or in-law suites where space is limited.
- Apartment Living: They are easier to install and take up less cabinet space than the standard 24-inch models.
Ease of Use
A good user experience means simple controls. Touchpads that are easy to wipe clean are better than mechanical knobs that can trap grime. Ensure the door opens and closes with a satisfying, solid click, not a flimsy sound.
10 Frequently Asked Questions (FAQ) About 18-Inch Dishwashers
Q: How much smaller is an 18-inch dishwasher compared to a standard one?
A: A standard dishwasher is 24 inches wide. The 18-inch model is six inches narrower. This saves significant cabinet space.
Q: Will an 18-inch dishwasher clean as well as a big one?
A: Yes, modern 18-inch models have similar washing technology, like strong spray arms and good filtration. They clean very effectively, but they hold fewer place settings.
Q: Are 18-inch dishwashers harder to install?
A: Installation is generally the same as a standard unit regarding plumbing and electrical connections. The main difference is fitting it into the smaller cabinet cutout.
Q: What is the typical capacity of an 18-inch model?
A: Most 18-inch dishwashers hold between 8 and 10 standard place settings. A place setting includes a dinner plate, bowl, cup, and silverware.
Q: Is condensation drying better than heated drying?
A: Condensation drying uses less electricity because it relies on residual heat. Heated drying dries faster but costs more to run over time.
Q: Can I put plastic items in any 18-inch dishwasher?
A: You can, but always check the manual. If the model lacks a dedicated heating element, plastic placed near the bottom might not dry completely.
Q: Do these smaller models have good filter systems?
A: Quality models use self-cleaning filters that grind up food particles. You still need to clean the filter manually every few months for best results.
Q: How loud are these smaller units usually?
A: Quiet models usually operate between 44 and 49 dBA. Always check the specifications sheet for the exact noise rating.
Q: Should I choose stainless steel or plastic tub material?
A: Stainless steel is recommended. It increases durability, reduces noise, and handles higher temperatures better than plastic.
Q: Where should I place my silverware for the best clean?
A: Place forks and spoons facing down for better rinsing, but place knives facing up for safety when unloading. Mix items up so they don’t nest together.
