MY REVIEW
We have had it 6 months now and love it.
We didn’t have a dishwasher when we moved in and a full sized one would have eliminated all our pot and pan storage. We took out a cabinet and this mini one fit perfectly. The measurements provided are spot on. There are adjustable “legs” on the bottom to raise it if needed, and the design just looks awesome.

MY REVIEW
Great value for an 18 inch dishwasher that most of the industry beats you up on the price, because it is not as common as the 24 inch.
I have used this dishwasher 14 times and have absolutely no problem with it or complaints as to how it runs at this point. It is extremely quiet and cleans well. Time will only tell if it is durable but for the price, I could have it fixed a half a dozen times before it catches up in price with the Bosch!

MY REVIEW
The Avanti DWF18V3S 18-Inch Dishwasher has been a game changer for my small kitchen, where a full-size model just wouldn’t fit. After six months of use, I can confidently say it operates quietly and efficiently, consistently delivering spotless dishes even when fully loaded.
I’m still impressed with this dishwasher months later; it accommodates up to 10 place settings, which is a pleasant surprise. Initially, I was skeptical about the brand, but it has proven to be robust and aesthetically pleasing. I found that running a high-temperature cycle before the actual wash helps ensure the water is hot enough, and the results speak for themselves — this machine cleans exceptionally well.

How to Choose the Best 18-Inch Dishwasher
Consider Size and Space Constraints
When selecting an 18-inch dishwasher, measure your kitchen space carefully to ensure it will fit. Compact dishwashers are ideal for smaller kitchens, apartments, and spaces where standard 24-inch models won’t fit. Also, decide if a built-in or portable model will work best for your setup, as built-ins require cabinet installation, while portable models offer more flexibility.
Look for Energy Efficiency
Energy Star-certified dishwashers are more eco-friendly and can reduce your utility bills over time. Check for energy-efficient features like eco-wash modes, delay start, and stainless-steel tubs that retain heat, which can lead to better drying performance.
Evaluate Noise Levels
If you have an open-concept kitchen or prefer quieter appliances, look for models with low decibel ratings (typically around 45–50 dBA). Brands like Bosch and Miele offer models that operate quietly, which can make a big difference in noise-sensitive homes.
Check Interior Capacity and Rack Flexibility
Capacity is crucial, even in an 18-inch dishwasher. Look for features like adjustable racks, third racks for utensils, and fold-down tines for larger dishes. These additions maximize space and help fit a variety of cookware types.
Choose the Right Wash Cycles
Depending on your cleaning needs, choose a model with the wash cycles you’ll use most, like heavy-duty for pots, glass cycle for delicate items, and quick-wash for lighter loads. The variety of wash settings helps in managing diverse cleaning needs efficiently.
