Most conventional dishwasher models are built to fit a 24-inch wide space underneath the kitchen counter. There is also a more compact size of 18 inches. Most of these models attach to a hot-water pipe, drain, and electrical line. There are also portable designs that can be rolled around the kitchen for convenient storage, and attach to the kitchen faucet when in use.
When choosing the perfect dishwasher for your kitchen, consider:
When it comes to picking out a dishwasher, there's really only one significant difference between lower priced models and higher priced models: Noise. While sensors and special features do play a significant role, when it comes down to it, lower-priced dishwashers can clean dishes just as well as higher priced dishwashers, but at a higher decibel. Consider whether you or your family has any light sleepers for any late night dishwasher runs. If you don't get a chance to hear and see your model work before purchasing, do your research online and see what other owners of the same dishwasher say about its noise level.
Other differences can include water and energy saving devices, designs that make it easier to load or unload the dishwasher, sensors that reduce the length of washing, and different types of wash cycles. Make sure your dishwasher has the basic cycles, including regular, pots and pans, and economy. Additional cycles can include glass, rinse, quick wash, etc. You can expect to pay a little more with each additional cycle.
The general rule is that the more places there are that spray water, the cleaner your dishes will be. Check inside the dishwasher to make sure that at the very least, water is sprayed from the bottom, top, and under the top rack. Sensors aren't necessary, but they can help save water and reduce the length of washing. Many of these work by measuring the cloudiness of the water, and deciding whether or not additional rinse cycles are necessary.
