The 7 Best 18-inch Dishwashers September, 2019 (And 2 Other Models)

Based on many of its 301 reviews, the SPT SD-9241W 18-inch portable dishwasher doesn't seem to cause any headaches when it comes to cleaning performance. Of course, it doesn't have to deal with as many dishes as your standard built-in model -- being the 18-inch portable version that it is -- but a unit that does its number-one job in a manner that's more than satisfactory for its customers should never go unappreciated. This, along with a lot of reviews commending it for operating quietly, has earned the SD-9241W 4 stars. Interestingly, its 55dB noise rating is actually above the average across all dishwashers, but smaller dishwashers tend to be more noisy and, in this case, the numerous feedback backing its relative quietness can't be discounted.

This fellow is not without potential issues, despite being ranked as the best 18-inch dishwasher in this list (Learn how we rank items), with a confidence level of 98 (More on confidence levels). Many reviewers gloat about how long its standard wash cycle is (cycle duration is a common point of dissatisfaction across all types of dishwashers), and the fact that it doesn't completely dry dishes didn't go unnoticed among customers. Apparently, this last issue can be remedied by cracking the door open after the cycle to help air-dry the dishes. Also, reports of this 18-inch portable dishwasher arriving damaged, dented, or with a dislodged element seem to fester in its critical reviews. One customer even remarked that the biggest challenge with this item is to have it ((Q))arrive undamaged.((Q)) Well, it's a good thing warranties exist for cases like this, and its ratio of 1-star ratings being around 16% when we looked at it is still in the healthy range, especially for dishwashers

In the end, this Sunpentown unit still left most of its customers satisfied. So if good reviews are of utmost importance to you, this dishwasher's mostly-good feedback should probably be enough to seal the deal.

Scanning through some of the Bosch SPX68U55UC's 75 total reviews, a lot of people appear to have been pleasantly surprised by how well it accommodates a variety of dish shapes and sizes, considering that it is, after all, an 18-inch built-in dishwasher with only 10 place settings (as opposed to the 14 place settings usually found on standard-size models). It has also been praised quite a lot for its cleaning ability, with some buyers even describing their dishes as ((Q))sparkling clean((Q)) right after being washed in this said unit.

However, what seems to set it apart from many others in this top 7 list of 18-inch models is the overwhelming positive feedback about it being a quiet dishwasher. Not a few reviews contain remarks about the SPX68U55UC being so quiet that their owners had to rely on the InfoLight feature (which indicates if a cycle is ongoing) to make sure that the unit was indeed running. Such a claim may potentially be too good to be true, but picture this: many 18-inch dishwashers in our database have already been praised for their quietness at a noise rating of around 55dB. This Bosch model, meanwhile, boasts a significantly-lower 44dB max noise level.

Perhaps the most common complaint about this dishwasher concerns its olfactory appeal. There have been complaints about it having an ((Q))overwhelming((Q)) bad odor, especially during the first several uses. It also doesn't dry dishes excellently, but this is a complaint we see a lot across dishwashers in general.

In the end, the SPX68U55UC has earned a 4-star rating. This just shows that it is really a strong contender if you're looking for a quiet 18 inch dishwasher, seeing that it's Alphachooser's second best 18-inch dishwasher 2019 in this specific subcategory.

This semi-integrated model from Frigidaire didn't make it as an Alphachooser good choice of our top 7 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 ((Q))very quiet,((Q)) 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 1390 reviews involve the ((Q))wonky((Q)) 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
