We all depend on the best dishwashers to keep up with the dirty dishes — running it day and night for a steady supply of clean crockery and utensils. And while all dishwashers use water and electricity to run, did you know that there are certain changes you can make to help lower your bills?
Nothing drastic is required to do this either. By making a small change, here and there, less money will be going down the drain (literally) and you could save yourself some time in the process too. Here are 7 dishwasher tips and tricks which will help save you money in the long-run.
1. Load your dishwasher to full capacity
Yes, it sounds like common sense, but many of us are guilty of running our dishwashers prematurely. This will either be because it smells quite bad, or because we need what’s in there sooner than we thought. But, you must resist the urge to run your dishwasher before it’s at full capacity — the empty space will only waste water as well as electricity, and this habit will add up to additional, unnecessary cycles over time.
If your dishwasher smells bad, investigate where it’s coming from. If it’s from residual food, scraping your plates more thoroughly could reduce this. You could also just shut the dishwasher’s door to better contain the smell before you run it. If the smell is something you really struggle with, you could also invest in a dishwasher which is designed to reduce this. The GE Profile Ultrafresh System (opens in new tab) cleans itself between cycles for instance — that’s right, someone finally made a dishwasher that doesn’t get smelly.
2. Load your dishwasher correctly
As well as filling your dishwasher to full capacity, you must load it correctly. Otherwise the entire cycle could be wasted, and you could end up washing items over and over. To load a dishwasher correctly, items shouldn’t be touching each other — this is so the water can flow through and clean effectively. Each item should also be in its designated position; you can refer to your manual if you need help on this.
Don’t forget that anything which could collect water, such as a glass or bowl, should be placed upside down. Lastly, it’s crucial that no items block the spray arm. If this can’t rotate, then the whole cycle will fail. If you’ve got particularly tall items in the lower rack which touch the spray arm, you can raise the upper rack to accommodate them.

3. Don’t bother rinsing plates
Here, we refer to pre-rinsing items in the sink prior to loading them in the dishwasher. Your dishwasher is designed to clean dirty crockery, residual sauce and all, so the water and time spent pre-rinsing is entirely wasted, with the exception of perhaps reducing the smell — but, is it really worth the cost? After all, if you use a cup of water to pre-rinse each plate in a dishwasher with 14 place settings, that’s 42 cups of water wasted on just one cycle. Your dishes will still emerge just as clean either way, so you should break this habit.
Of course, that's not to say you should chuck your leftovers in the dishwasher. Residual food should still be scraped away before loading the item — otherwise, you’re just going to block your filter, ruin the cycle, and then you’ll have to remove the food by hand later, which is pretty gross.
4. Don’t hand wash
It’s tempting to wash rogue items or a small stack of dirty dishes by hand at times. However, you should always rely on the dishwasher where you can. Using a dishwasher is actually the better option of the two. It uses less water on average, requires less hands-on time, plus it’s more hygienic as a dishwasher cycle can reach temperatures our hands can’t endure.

With this in mind, be sure to pick and choose which items you decide to wash by hand. Anything wooden or overly fragile should definitely be hand-washed, as should exposed cast iron. Remember, though, some things should never go in the dishwasher.
5. Use the Eco setting
Many dishwashers now offer an ‘Eco’ setting, which will use less water and electricity in exchange for a longer run time. This does mean you will be waiting around a little longer for clean dishes (some programs can take up to four hours from start to finish), but it will equate to a substantial saving on your bills over time. Bear in mind that an Eco setting will not provide as much cleaning power as a Heavy or Intense cycle, so reserve your heavily stained pots for these.
Some of the best washing machines also offer Eco settings, which is worth keeping an eye out for. This provides a similar performance — reduced water and electricity consumption for a longer program. This is another way you can easily save on your bills.
6. Use the timer
Everyone knows that the timer on appliances can come in use for delaying cycles until it’s convenient. For instance, your dishwasher could be ready to empty as soon as you get home from work. But, did you know that you could use this feature to save money if you’re on a time-of-use energy plan?
These electricity plans will charge more during peak hours, when energy is high in demand, and conversely less during off-peak hours. That means all you need to do is set your dishwasher to start during the reduced tariff, and you could make a saving. This is typically overnight or first thing in the morning depending on your location, but if you want more details on the exact timings, check out this is the cheapest time to do your laundry and save money.
7. Keep your dishwasher well-maintained
If you want to save money in the long run, you’ll want to help your dishwasher last as long as possible, so it requires fewer repairs and won’t need replacing as often. There are several ways you can do this. First, you need to learn how to clean a dishwasher, and get into the habit of checking the filter after each cycle. You’ll also want to make sure you don’t load it with something you should never put in a dishwasher. As well as damaging the items, this can potentially damage the dishwasher itself.
You should also descale your dishwasher regularly to extend its lifespan. This will keep any limescale at bay — white vinegar works brilliantly for this. Keep the salt reservoir topped up at all times too; this can deter limescale from building up in the first place.
