“Running your dishwasher at certain times can save energy and reduce costs, as electricity rates often vary throughout the day,” Lewis explains. For that reason, he suggests running your dishwasher in the evening after peak hours when electricity demand is lower and the power companies subsequently lower energy costs.

At off-peak times, typically at night, when most of us sleep, demand drops. To encourage people to use electricity during these quieter periods, energy companies, like us, sometimes offer cheaper rates. Other off-peak hours: Late at night (usually from around 11pm–6am).
Using dish soap in a dishwasher creates a thick, sudsy foam in the appliance that can overflow through the dishwasher door. This is due to the formula of dish soap that relies on suds and bubbles to clean dishes. On the other hand, dishwasher detergent relies mostly on enzymes to get your dishes clean.
Electric heating systems and tumble dryers tend to be the most expensive electrical items to run because they use large amounts of power over extended periods. Other high-cost appliances include electric ovens and immersion heaters.

Time-of-Day Smart Tip: Stagger the use of your oven and other large appliances, like the dishwasher or washing machine, to cut your energy consumption.
You can save even more money by running your dishwasher during off-peak hours, usually from 9 p.m. to 7 a.m. Many utility companies offer off-peak energy rates. And don't pre- rinse if your dishwasher can handle it.
