There’s nothing quite like the joy of unloading a fully cleaned dishwasher after a long day of cooking and entertaining. And with the GE Profile 18" Black Built-in Dishwasher, that joy may not be far off. This sleek and modern dishwasher has been a staple in my home for the past few months, and I must say, it does a fantastic job of cleaning table-ready dishes while saving me time on manual washing.

First things first, the dishwasher’s low-profile design is perfect for those with limited counter space or those looking for a seamless fit in their kitchen. The Piranha hard food disposal system is an added bonus, as it ensures my dishes are free from pesky food particles and clogs. The high-temperature rinse function is also a lifesaver when it comes to sanitizing and killing up to 99.9 percent of bacteria found on dishes.

However, there have been some minor drawbacks in my experience. While the racks are perfect for most dishes, I’ve found that my larger bowls tend to topple over when placed on the top rack. As for the digital controls on the door, I would have appreciated a more visible view of the cycle’s progress. These are minor setbacks in an otherwise stellar dishwasher.

All in all, the GE Profile 18" Black Built-in Dishwasher has been a reliable and efficient addition to my kitchen.

One of the things that immediately stood out to me was the ease of use. The control panel is located on the top of the dishwasher, making it simple to access and start a wash cycle. The dishwasher comes with six different wash cycles to choose from, giving you plenty of options for cleaning various types of dishes. Additionally, the 24-hour delay feature allows you to schedule a wash cycle for later, which is a great convenience when you’re busy.

One feature that I found particularly impressive was the built-in water softener. This is especially helpful if you live in an area with hard water, as it helps to ensure that your dishes come out clean and spotless. The water softener also makes it easier to wash your dishes, as it helps prevent mineral buildup that can damage the dishwasher over time.

However, there are a few drawbacks to using this dishwasher. For one, the noise level is on the higher side, which may not be ideal if you’re placing it in a smaller space where sound can easily carry.

The product dimensions are perfect for my small kitchen, and the delay start feature is a game-changer for my busy schedule. The dishwasher is super quiet, which is great considering I have an open floor plan.

However, there have been a few downsides. The control board can be unresponsive at times, which can be frustrating when trying to select a wash cycle or adjust the settings. Additionally, the soap dispenser door is quite tricky to close and requires some force to keep it in place. And let’s not forget about the packaging — it didn’t do the best job protecting the product during delivery.

Overall, this dishwasher does its job efficiently, but it’s not perfect. I have high hopes that the customer service team will resolve the warranty issue and provide the necessary feet for installation.

What is an 18-inch dishwasher?

An 18-inch dishwasher is a type of dishwasher that measures 18 inches in width, which is slightly larger than a standard 17–18 inch dishwasher. This size allows for more efficient loading of dishes and provides better overall capacity for larger families. However, it may require a larger space for installation.

Due to increased demand for larger, more spacious dishwashers, 18-inch models are becoming increasingly popular among homeowners. They offer more versatility in terms of accommodating larger dish sets and allowing for more efficient washing of larger volumes of dishes in one cycle. Additionally, many of these models come with advanced features designed to further improve performance and energy efficiency.

What are the benefits of an 18-inch dishwasher?

The primary benefits of an 18-inch dishwasher include increased capacity, improved washing performance, and enhanced energy efficiency. The larger size allows for more dishes to be loaded into the machine and better utilization of the available space. This results in fewer loads being required to complete the same amount of dishes, saving both time and water.

In addition, many 18-inch models come equipped with advanced features designed to further improve performance and efficiency. These may include soil sensors, which adjust wash cycles based on the level of dirt and food residue on the dishes, as well as more efficient heating elements, which reduce the time required for drying.

Are 18-inch dishwashers compatible with standard dishwasher cabinets?

While some 18-inch dishwashers are compatible with standard dishwasher cabinets, others may require a larger space for installation. It is essential to consider the dimensions of your kitchen and the existing cabinet configuration when selecting an 18-inch dishwasher. Additionally, measure the space between your countertop and any upper cabinets to ensure the dishwasher will fit both horizontally and vertically.

Some manufacturers offer 18-inch dishwashers with optional features, such as adjustable legs or modular design, to help accommodate different cabinet configurations. It is always recommended to consult the product specifications or speak with a representative from the manufacturer to ensure compatibility with your specific kitchen layout.

How much does an 18-inch dishwasher cost?

The cost of an 18-inch dishwasher can vary greatly depending on the brand, features, and energy efficiency ratings. On average, you can expect to pay anywhere from $800 to $1,500 for a high-quality 18-inch dishwasher. While this may be more than the cost of a standard 17-inch or 18-inch dishwasher, the increased capacity and performance offered by these models can make them a worthwhile investment for larger families or those with extensive dishware collections.

It is essential to compare the features and performance of various 18-inch dishwashers before making a purchase to ensure you are getting the best value for your money. Additionally, consider energy efficiency ratings and potential cost savings over time, as these can contribute significantly to the long-term cost of ownership.

What features should I look for in an 18-inch dishwasher?

When selecting an 18-inch dishwasher, consider the following features to ensure optimal performance and energy efficiency: variable wash/rinse cycles, adjustable upper racks, soil sensors, and energy-efficient heating elements. These features can help improve washing performance, reduce water and energy consumption, and minimize dry time.

Additionally, consider the noise level, capacity, and convenience features such as delayed start or auto-dispersal functions. These features can help improve the overall user experience and make the dishwasher a more integrated and hassle-free part of your daily routine. When shopping for an 18-inch dishwasher, it is essential to balance your preferences and requirements with your budget to find the best model for your needs.

Do 18-inch dishwashers use more water than standard dishwashers?

While 18-inch dishwashers do use more water than standard 17-inch or 18-inch dishwashers, a higher capacity for water usage does not necessarily equate to greater water waste. Many 18-inch models come with advanced features designed to optimize water and energy consumption, resulting in improved overall efficiency.

For example, some 18-inch dishwashers feature soil sensors, which adjust wash cycles based on the level of dirt and food residue on the dishes.
