This grid shows you the most energy and water efficient dishwashers available in Australia. The dishwashers are initially sorted by Energy Rating first and lowest price second. This means that if you have a bunch of dishwashers with the same energy rating, the cheapest ones will be higher up.
This makes it easy to spot the cheapest dishwasher of a certain energy rating.
You can refine your search with the options at the top of the screen. The first two options you have are Place Settings and Price, so you can make sure you are only looking at dishwashers in your price and size range.
The next two options are to only show dishwashers over a certain energy or water star rating - if the grid is empty try relaxing these options to a lower star rating.
The final option is for real energy saving freaks. It filters the list to only show dishwashers with dual water connections. That means dishwashers with a hot water connection as well as the usual cold water connection.
It is usually better to have a hot water connection because the water-heaters in all dishwashers are not very efficient, and it is highly likely that your house hot water system will use a lot less energy. If that is the case then it makes sense to heat the water outside of the dishwasher.
If your hot water system is electric heat pump, gas, or solar, then this option will save you a lot of energy compared to the kwh/year figure quoted. However at the time of writing there were only 2 dishwashers with this feature.
One thing yo watch out for here is if you have instant gas hot water. Because it takes a while for the water to heat up it is highly likely that only cold water gets into the dishwasher for each fill. This kind of defeats the point of a hot water connection. A neat way round this is discussed here

The default order for the dishwashers in the grid is by Energy Rating and then price.
You can change this order with the drop down box in the top right corner:
Most of the options on this list are self explanatory. These ones may require some explanation...
This sorts the dishwashers by the amount of electricity they use over a year. Electricity is measured in kiloWatt hours (kWh). The dishwashers with the lowest consumption will be first.
Sort By Total Cost
Sorts the dishwashers by the total cost of buying and using the dishwasher over the time period in the 'years' dropdown box.
This is the cost of the appliance plus the cost of the energy that will be needed to power the dishwasher, plus the cost of the water to run the dishwasher. You can change electricity and water costs in the Advanced Options.
You may well find that the cheapest dishwashers to buy are not the cheapest to own over 10 years or so.
This sorting method is really useful for quickly identifying the dishwashers with the best balance of price and efficiency.
If a dishwasher is very energy and water efficient for the price then it will be towards the top of this list when you sort by total cost.
Sorts the dishwashers by the cost of energy needed to use the dishwasher over the time period in the 'years' dropdown box.
Sorts the dishwashers by the cost of water needed to use the dishwasher over the time period in the 'years' dropdown box. It is interesting to see that the cost of water can be close to the energy cost!
