The 5 Best 18-inch Dishwashers As Of September, 2020 (And 4 Other Models)

Despite a lower review sample, taking into account its average ranking of 88%, we conclude that the Edgestar BIDW1802 is, as of now, Alphachooser's best 18-inch dishwasher 2020. Alphachooser also concludes that our sample of 113 reviews from our sources gives us a safe-enough confidence level (more on confidence levels) that justifies calling it the most interesting choice as of now.

This semi-integrated model from Frigidaire didn't make it as Alphachooser's second best 18-inch dishwasher 2020 of our top 5 18-inch dishwashers for nothing. It has secured a great number of reviews praising it for its physique, with its stainless steel finish (for the FFBD1821MS variant, at least) giving its exterior a sleek and modern look. Furthermore, praises for its cleaning ability come aplenty, even with its light cycle -- but note that most of the reviewers who've written this remark have also mentioned that they routinely pre-rinse extra-dirty dishes in the first place.

Opinions about the Frigidaire FFBD1821MS' noise level isn't as definitive, however. Some consumers have noted that it is "very quiet," while some expressed wishes for it to be less noisy. As such, perhaps the most solid benchmark we can rely on at this point is really its 55dB noise rating, which is relatively-noisy, but its not unexpected for a semi-integrated compact dishwasher.

Common complaints found among its 434 reviews involve the "wonky" silverware basket and this semi-integrated dishwasher's height (or lack thereof), which is not the tallest but is definitely taller than the category average. So if you're iffy about having a dishwasher that may potentially leave some space between it and the countertop, then we suggest that you take diligence in comparing measurements before taking the plunge.

In the end, the Frigidaire FFBD1821MS was able to traverse past its imperfections, winning an impressive number of fans in the process

In spite of being a narrow dishwasher, the Bosch SPE68U55UC managed to a have a sound rating of only 44dBA. This is a rare feat for built-in models its size, and so it's not entirely a shock that its buyers have expressed surprise about how quiet its operation is. The silver exterior has been praised for its stylish looks, as well.

Mainly due to the third rack (which appears to be mainly used for utensils and flatware), customers seem to be more than satisfied with this 18-inch dishwasher's capacity -- with a number of buyers saying that it felt like this model can hold almost as much as a 24-incher . This ability to utilize space effectively definitely makes the SPE68U55UC feel like a catch for space-strapped-kitchen owners. According to many of its 33 reviews, this 4.5-star compact dishwasher also has great cleaning ability -- washing baked-on pans and dried-on bowls with apparent ease.

We didn't really find any major complaints from its customers, except for some expressing preference for metal feet over the plastic ones found in this model.

With the impressive number of people who have reported utmost satisfaction with this dishwasher, as well as the obvious lack of any major setbacks reported by consumers, the Bosch SPE68U55UC more than deserves its spot as an Alphachooser good choice in this AlphaChooser top 5 listing.

The DDW1802EBLS offers seven preset programs, which is quite-respectable, especially for an 18-incher.

The Frigidaire FFPD1821MW seems to pack quite a punch within its 18-inch body. The dishwasher has racked up 99 reviews across multiple sources, and its aggregated rating is at 4 stars. According to many of these customer feedback, it doesn't fail at delivering sparkling-clean dishes (granted, extremely-dirty dishes with dried-on gunk still have to be pre-rinsed). Some even reported that they feel like they're consuming less dishwasher compared to their previous models, and yet are getting better results. Furthermore, the Frigidaire FFPD1821MW has also been praised quite a lot for its looks, and the "easy-to-clean" stainless steel interior has gained it some fans, as well.

While it's nothing disruptive, this 18-inch dishwasher's 59dB noise rating isn't its most encouraging feature. It's true that models that veer away from the standard size tend to have higher noise ratings, but the FFPD1821MW clearly has a lot of customers wishing that it was a bit quieter. Another complaint we've seen more than a few times concern the silverware basket. Reviewers have pointed out that it feels quite wonky and that they wish it was bigger. Also, the silverware slots inside aren't too accommodating for larger utensils. Luckily, the slots can be removed in favor of having just a plain old basket.

Still, the Frigidaire FFPD1821MW appears to have shown customers all that it is capable of doing, which has left a lot of people satisfied, based on the reviews we have encountered. Due to this, it's been named as an Alphachooser good choice by our system (Learn how we rank items) with a 72 confidence level (More on confidence levels).

The DW1831D0WE keeps to an 18-inch body, but offers a washing lineup similar to full-size models -- including six programs (Eco, Glass, Heavy, Normal, Rapid, Rinse) and three cycle options (Sanitize, High temperature, Heated dry).

The PDW1860KSS is an 18-inch dishwasher that makes quite a lot of washing noise with its 60-dBa sound rating and whose key highlights are its natural-air-drying cycle, nylon racks, and stainless-steel tub.

The EIDW1805KS apparently auto-adjusts the cycle time by relying on a Smart Soil sensor -- a more-advanced feature than what we would expect from a 18-inch dishwasher.
