Dishwashers are among the most convenient appliances to use. Getting a top-quality dishwasher will ensure you never have to leave the dishes dirty overnight.

But what is overnight wash dishwasher? Is there even such as thing? Here’s what you need to know.

What Is an Overnight Wash Dishwasher?

Overnight wash dishwashers are dishwashers that have the overnight wash or delay feature. Often, loud dishwashers have a delay feature that enables users to set the dishwasher to clean when they’re not home. When you hit the overnight/delay button, dishwashers spritz the dishes with water to keep them from crusting until the cycle begins.

Not all dishwashers have these features, and it is not safe to leave a dishwasher running unattended unless they’re designed with safety features built-in. Fire and flooding can cause major damage to your home if anything goes wrong with the dishwasher. Never run a dishwasher unless there’s someone around to switch it off after it finishes its cycle.

Three Times When You Can Run Your Dishwasher Overnight

Running a dishwasher overnight can be safe if:

#1 It Has an Automatic Turn-Off Feature

While most dishwashers in the market come with this feature, some brands do not make dishwashers with the feature.

If you’re planning to purchase a dishwasher, it’s best to buy one with the automatic turn-off feature since you will be free to leave it unattended and leave your home or go to bed. When the cycle ends, the dishwasher will turn off automatically.

It’s best to remember that the feature only prevents heat build-up and electronic malfunctions. When you leave the dishwasher unattended, you still bear the risk of flooding the kitchen. But you could prevent this by leaving the unit in the air-dry mode.

Air drying will save you electricity and also prolong the life of your Tupperware.

#2 The Door Opens Automatically for Air Drying

Most new dishwashers come with this feature. The dishwasher’s door pops open when the washing cycle is complete to allow air-drying. This way, it also prevents plastic utensils from getting smothered by heat.

Getting a dishwasher with this feature is an excellent way to save electricity. It also spares you from using your Topzero sink and acrylic kitchen sinks as plate dryers.

#3 It Stops Mid-Cycle if There’s a Problem

Your dishwasher must be capable of halting mid-cycle if something goes wrong if you intend to run it overnight. Many new models are designed to do this, but it’s not a standard feature.

It’s best to purchase a high-quality dishwasher that is capable of lasting for years and that can stop mid-cycle if there are problems with the duct, the vent fan, or the heating element. Getting a machine with these features can be costly, but they’re worth getting since they prevent damage to your property.


While “overnight dishwashers” aren’t niche products that exist yet, most dishwashers in the current market offer an overnight wash or delay feature. Regardless of which dishwasher you own, it’s best to run maintenance checks once every two weeks at a minimum so it can last for a long time. This will ensure you don’t have to deal with unforeseen leakage and avoid waterproofing your cabinet under your kitchen sink.
