The Ultimate Buying Guide for 18-Inch Dishwashers
Thinking about getting a smaller dishwasher? 18-inch dishwashers are a fantastic choice for small kitchens, apartments, or when you just don’t need a giant machine. They save space but still clean your dishes well. This guide helps you pick the best one for your needs.
Key Features to Look For
Not all small dishwashers are the same. Look closely at these important parts:
Capacity and Racks
- Place Settings: Even though they are small, check how many place settings they hold. Most 18-inch models hold 8 to 10 settings.
- Adjustable Racks: Can you move the top rack up or down? This helps fit tall glasses or big plates easily.
- Cutlery Basket: Does it have a good spot for silverware? Some models have a flat third rack instead of a basket.
Performance and Efficiency
- Cleaning Cycles: You need more than just “Normal.” Look for Heavy Wash, Quick Wash, and maybe a specialized cycle like “Sanitize.”
- Drying Method: Some use heat to dry (faster but uses more energy). Others use condensation drying (slower, but gentler on plastic).
- Noise Level (dBA): Dishwashers run often. Look for a decibel (dBA) rating under 50. Lower numbers mean quieter operation.
Important Materials That Matter
The materials inside the dishwasher affect how long it lasts and how well it cleans.
Interior Tub Material
- Stainless Steel: This is the best choice. Stainless steel tubs dry dishes faster and resist stains better than plastic. They also help keep the noise down.
- Plastic: These tubs are cheaper upfront. However, they can sometimes hold onto odors or stains over time.
Spray Arms
Look for dishwashers with multiple spray arms—usually one on the bottom and one in the middle. Better spray coverage means cleaner dishes. High-quality models use strong, non-flexing plastic or stainless steel for these arms.
Factors That Improve or Reduce Quality
What makes one 18-inch dishwasher better than another? It comes down to smart design and build quality.
Quality Boosters
- Hard Food Disposer: Good models grind up leftover food bits, preventing clogs in the filter.
- Water Softener System: If you live where the water is hard (lots of minerals), a built-in softener protects the machine and prevents white spots on your glassware.
- Delayed Start Option: This lets you run the dishwasher when electricity rates are lower or when you are away from home.
Quality Reducers
- Thin Door Panels: If the outer door feels flimsy when you press it, the insulation and sound dampening might be poor, making the machine louder.
- Cheap Filters: Simple, one-piece filters need cleaning often. Complex, multi-stage filters catch more debris and require less frequent maintenance.
User Experience and Use Cases
An 18-inch dishwasher fits specific lifestyles perfectly.
Who Needs One?
- Apartment Dwellers: They fit easily into smaller kitchen layouts where a standard 24-inch unit won’t work.
- Couples or Singles: If you cook often but don’t use many serving dishes, you can run the dishwasher every night without wasting water by running a half-empty large machine.
- Secondary Kitchens: They are great for basement bars, in-law suites, or outdoor kitchen areas.
When you use it, make sure you load it correctly. Because space is tight, avoid stacking dishes directly on top of each other. Proper loading ensures the water jets reach every surface. A good user experience means you rarely have to rewash items.
10 Frequently Asked Questions (FAQ) About 18-Inch Dishwashers
Q: How much space do I need for installation?
A: You need a space that is exactly 18 inches wide, about 34 inches tall, and 24 inches deep for the standard built-in model.
Q: Are 18-inch models less energy efficient?
A: Not necessarily. Since they use less water per cycle, they can be very efficient. Always check the Energy Star rating.
Q: Can I fit large pots inside?
A: Large stock pots are difficult. You might need to handwash very big cookware. Focus on dinner plates, bowls, and glasses.
Q: Do they connect to the same plumbing as 24-inch models?
A: Yes, the water inlet and drain hose connections are usually the same standard sizes.
Q: How loud are these smaller units?
A: A good 18-inch model should operate around 46–52 dBA. This is similar to a quiet conversation.
Q: What is the main difference between a built-in and a countertop 18-inch model?
A: Built-in models are permanently installed under the counter. Countertop models sit on your counter and often connect temporarily to the sink faucet.
Q: How often should I clean the filter?
A: If you use it daily, check and rinse the filter once every month to keep cleaning performance high.
Q: Are 18-inch dishwashers more expensive per cycle?
A: No. Because they clean fewer items, they generally use less water and electricity per load than a full-sized machine.
Q: What is “condensation drying”?
A: This method uses the heat retained by the stainless steel tub walls to evaporate water off the dishes, rather than using a heating element.
Q: Do I need special detergent?
A: No, you can use the same standard dishwasher pods, gel, or powder that you use in any other dishwasher.
