Dishwasher Delay Start: What It Does and When to Use It

What is delay start on a dishwasher?

Delay start is a timer feature that lets you schedule when a wash cycle begins. Instead of pressing Start and having the cycle run immediately, you set a delay of one or more hours. The dishwasher waits until that time, then starts automatically. It does not change how the cycle washes; it only controls when the cycle begins.

This feature appears on many built-in dishwashers, countertop, and portable dishwashers from various manufacturers. It is often labeled as "delay start," "delayed wash," or simply "timer." You may see a clock icon on the control panel, or a button marked "Delay." If you are shopping for a new dishwasher, it is worth checking the control panel or the specification sheet to see whether delay start is included.

How to set delay start on your dishwasher

The exact steps vary by model, but the basic idea is consistent. Load the dishwasher, add detergent, and select the wash cycle you want. Then press the Delay button. Use the up and down arrows or the number pad to choose how many hours you want to wait. After the delay time is displayed, press Start. The dishwasher will lock the controls and begin the cycle after the set time.

Some models let you choose a specific time of day rather than a countdown. For example, you can set the dishwasher to start at 2 a.m. instead of 7 hours from now. Check your owner's manual for the available delay range and the exact method for your unit. If you are not sure whether your model has delay start, look for a button with a clock icon or the word "delay" on the control panel.

• Check the owner's manual for your model's specific delay range and settings.
• Make sure the delay is long enough for the cycle to finish when you want it to.
• Some models allow you to program a specific start time instead of a countdown.

Using delay start for off-peak energy

One of the main reasons to use delay start is to run the dishwasher during off-peak hours when electricity may cost less. Many utility companies charge higher rates during peak demand times, often late afternoon and evening. By delaying your dishwasher to run overnight or early morning, you can shift your energy use to times when demand is lower.

Delay start does not change how much energy the dishwasher uses per cycle. Its benefit is timing. If your utility offers time-of-use rates, running the dishwasher during off-peak periods can reduce your energy bill. Contact your utility provider to find out what off-peak hours apply in your area. Even without special rates, shifting energy use away from peak times can reduce strain on the electrical grid.

ENERGY STAR certified dishwashers are designed to be efficient, and pairing one with delay start is a simple way to manage when that efficiency is used. For more on reading the energy label and understanding a dishwasher's consumption, see our guide to the EnergyGuide label.

When delay start makes sense

Delay start is most useful when you want the dishwasher to run at a specific time. For example, you can load it after dinner, set a delay for overnight, and wake up to clean dishes. It can also help you avoid running the dishwasher when you are around to hear it, especially if you have a quieter model. Running the dishwasher while you sleep is a common use, though you should ensure your model is quiet enough. See our quiet dishwasher guide for models with low noise levels.

You might also use delay start when you have a full load but want to take advantage of an off-peak rate that begins later. The ENERGY STAR program recommends running full loads because a dishwasher uses roughly the same energy and water regardless of how many dishes are inside. Delay start lets you load the dishwasher after dinner, wait until the off-peak window begins, and still have a full load ready.

• You have a time-of-use electricity plan.
• You want to reduce noise while you sleep or work.
• You want clean dishes ready at a specific time, such as the morning.
• You prefer to run the dishwasher with a full load at a set time.

Tips for getting the most from delay start

Delay start works best when you pair it with good loading habits. The ENERGY STAR program recommends scraping dishes instead of rinsing and running full loads to save both energy and water. Delay start does not affect efficiency directly, but it helps you run the dishwasher at a time that fits your routine. To understand which cycle to pair with a delayed start, read our explanation of dishwasher cycles.

If you plan to delay the start overnight, avoid using a cycle that requires a very hot rinse and heated drying if you want to let dishes air dry. You can turn off the heated dry option and leave the door slightly ajar after the cycle ends to help moisture escape. This can be a good way to save energy while still getting clean dishes.

• Load the dishwasher completely before setting the delay.
• Avoid delays longer than needed, as food residue can dry onto dishes.
• If your dishwasher has a heated dry option, consider turning it off and letting dishes air dry overnight.

Questions

Does delay start save energy?

Delay start itself does not change how much energy the dishwasher uses. Its benefit is timing. If your utility charges lower rates at certain times, running the dishwasher during those periods can lower your energy bill. The dishwasher's cycle and efficiency depend on the model and the cycle you choose.

Can I set delay start on any dishwasher?

Not all dishwashers have delay start. It is a common feature on many modern built-in and countertop models, but you need to check the control panel or specifications. If you are shopping, look for models that list delay start among their features.

How long can I delay the start?

The delay range varies by model. Check your owner's manual for the maximum delay and the intervals you can set. Some models allow you to program a specific start time rather than a countdown.

Is delay start the same as a timer?

Yes, delay start is essentially a timer that tells the dishwasher when to begin its cycle. Some models let you select a specific time of day instead of a countdown from the present.

Does delay start affect wash performance?

No. The wash cycle is identical whether you start it immediately or after a delay. The only difference is when the cycle begins.
