The Ultimate Buying Guide for Your 18-Inch Dishwasher
An 18-inch dishwasher is a fantastic choice for smaller kitchens, apartments, or for households that don’t generate a huge pile of dishes every day. These compact models save space without sacrificing cleaning power. Choosing the right one involves looking closely at a few key areas. This guide will help you pick the best fit for your home.
1. Key Features to Look For
When shopping for your new compact cleaner, pay close attention to what it can actually do. These features make a big difference in your daily life.
Washing Performance and Cycles
- Spray Arms: Look for dishwashers with multiple spray arms (usually two or three). More arms mean water reaches every corner, cleaning better.
- Cycle Variety: A good model offers different settings. You need a heavy-duty cycle for baked-on messes and an eco or quick cycle for lightly soiled items.
- Drying Method: Some use heat coils to dry dishes, while others use condensation drying. Condensation drying saves energy and is often gentler on plastics.
Capacity and Racks
- Tub Size: Even in 18-inch models, check the internal layout. Some offer flexible racks that you can adjust for tall glasses or large bowls.
- Cutlery Basket: Ensure the basket is sturdy and fits your utensils well. Some premium models offer a third slim top rack for silverware instead of a basket.
Noise Level
Noise is measured in decibels (dB). For an open-plan living space, aim for models under 50 dB. Anything below 45 dB is very quiet—you might forget it’s running!
2. Important Materials
The materials inside the dishwasher affect its lifespan and cleaning effectiveness.
Stainless Steel Tub vs. Plastic Tub
- Stainless Steel Tubs: These are superior. They handle high heat better, which improves drying performance. They also tend to last longer than plastic tubs.
- Plastic Tubs: These are less expensive upfront. However, they can sometimes stain over time and might not retain heat as effectively for drying.
Racks and Baskets
High-quality dishwashers use durable racks coated in nylon or vinyl. This coating protects your dishes from chipping and rusts much slower than bare metal.
3. Factors That Improve or Reduce Quality
Several technical factors determine how long your dishwasher lasts and how well it cleans.
What Boosts Quality:
- High Water Temperature Settings: Models that can heat the water hotter sanitize dishes more effectively.
- Filtration System: A good filter catches large food particles so they don’t redeposit onto your clean plates. Easy-to-remove filters make cleanup simple.
What Lowers Quality (or Performance):
- Long Cycles for Basic Cleaning: If the normal cycle takes over two hours, the machine might not be optimized for efficiency.
- Plastic Components in High-Stress Areas: If the spray arms or the main latch are made of cheap plastic, they are more likely to break first.
4. User Experience and Use Cases
Think about where and how you will use this appliance.
Apartment Living
For renters, look into portable 18-inch models. These often sit on the counter or roll on wheels and connect temporarily to your kitchen faucet. They offer flexibility if you move.
Efficiency Matters
Check the Energy Star rating. An efficient dishwasher saves you money on your water and electricity bills over the years. Look for models that use less than 4 gallons of water per standard cycle.
Installation Type
Most 18-inch models are designed for built-in installation under the counter, fitting into the space where a standard trash compactor might go. Make sure your plumbing connections are accessible for installation.
10 Frequently Asked Questions (FAQ) About 18-Inch Dishwashers
Q: Are 18-inch dishwashers as powerful as 24-inch models?
A: Yes, they often are! They use the same heating elements and pump technology. They just hold fewer dishes. They clean just as effectively.
Q: How many place settings fit inside an 18-inch dishwasher?
A: Typically, an 18-inch model holds between 8 and 10 standard place settings. This is usually enough for a couple or a small family.
Q: Do these compact models save water?
A: Generally, yes. Because the tub is smaller, they use less water per cycle than full-sized machines, especially if they have good efficiency ratings.
Q: Can I install an 18-inch dishwasher myself?
A: Installation is similar to a larger model, involving water lines and drainage. If you are comfortable with basic plumbing, you can do it. Otherwise, hire a professional.
Q: What is the average lifespan of a quality 18-inch dishwasher?
A: A well-maintained unit with a stainless steel tub should last between 10 and 12 years, similar to larger dishwashers.
Q: Are 18-inch models always louder?
A: No. Noise level depends on insulation and motor quality, not just size. Always check the decibel rating (dB) listed in the specifications.
Q: What is the most common alternative installation for this size?
A: The most common alternative is a countertop model, though these are usually smaller than 18 inches. True 18-inch units are designed to fit under the counter.
Q: Should I get one with a third rack?
A: If you use a lot of small items like espresso cups or long utensils, a third rack maximizes the space in the two main racks below it. It is a great upgrade.
Q: How do I clean the filter in a compact dishwasher?
A: Most modern filters twist out easily from the bottom of the tub. You rinse the screen under the sink to remove trapped food debris. Check your manual for specific instructions.
Q: What should I do if my dishes are coming out wet?
A: If you chose a model without a heated dry option, you must leave the door slightly ajar after the cycle finishes. This lets the steam escape, allowing condensation drying to work.
