  • Built-in might not have top or side panels; must be enclosed and anchored to prevent it from tipping forward when fully loaded dish racks are pulled out.
  • Semi-integrated is a built-in type that allows you to fit a panel to the door to match the rest of your kitchen cupboard doors.
  • Fully integrated is a built-in with the whole front matching your kitchen and the controls inside the door.
  • Benchtop is a compact dishwasher that sits on top of your kitchen bench, rather than being installed into cabinetry.

Recommended View more details.

We recommend dishwashers which score at least an 80% CHOICE Expert Rating, at least 75% washing performance score, at least 80% drying score and no other scores below 60%.

CHOICE Expert Rating View more details.

The CHOICE Expert Rating is made up of washing performance (65%), drying performance (25%) and energy efficiency (10%).

Washing score View more details.

We assess how well the dishwashers can remove food such as oats, spinach, egg yolk, baby cereal, butter, and tea stains that have been dried overnight without being rinsed first. Our test is based partly on the current Australian standard and partly on the International Electrotechnical Commission (IEC) draft standard.

Drying score View more details.

Reflects how dry the dishes are 30 minutes after the normal cycle has finished. During this time the doors are left closed (unless the dishwasher has an automatic door opening function that is activated at the end of the program).

Energy efficiency score View more details.

Based on the amount of energy used per place setting by the dishwasher on the tested program. The less energy used, the higher (better) the score.

Energy use (kWh) View more details.

This is the energy use of the program we selected. We use this, plus the number of items washed, to formulate our energy efficiency score. A dishwasher generally makes up around 2.9% of the annual household energy usage. Look for the smallest number in this column so you aren't paying as much in the long run.

Water use (L) View more details.

How much water was used (in litres) by the program we selected. We show this to give you an idea of how much of a water bill you'll be in for depending on your patterns of use.

Noise level (dBA) View more details.

Measured from one metre away from and one metre above the dishwasher, which is placed within cabinetry. The noise level varies depending on kitchen layout, but our reading gives a comparative measure. For reference, a normal conversation is around 60dB and a whisper is between 20 and 30dB. A difference of 3dB is noticeable to the human ear.

Program time (minutes) View more details.

How long the program that we selected took (in minutes). This time can vary based on whether the dishwasher has a dirt sensor (automatic), how full it is and the program you select.

Year tested View more details.

Due to a slight change in our dishwasher test method, results for dishwashers tested from 2024 onwards are not directly comparable with results from tests conducted in 2023 or earlier, and should be considered separately.

Shop Ethical rating View more details.

Shop Ethical rates the environmental and social impact of the company (not the product) using independent sources. This rating is not included in our total score. N/A means there is no rating for that company.

D
Energy star rating View more details.

Claimed by the manufacturer. The more stars, the more energy-efficient the dishwasher.

4
Claimed energy use (kWh/year) View more details.

Energy use per year, claimed by the manufacturer. Look for lower numbers to decrease your energy consumption.

225
Energy star program View more details.

The wash program used to determine the energy star rating. Manufacturers tend to choose a program that uses the least energy and water to get the most stars possible.

Normal 45°C
Water star rating View more details.

Claimed by the manufacturer. The more stars, the more water-efficient the dishwasher.

4.5
Claimed water use (L) View more details.

The claimed water use per wash cycle. Look for lower numbers to decrease your water consumption.

12.3
Reliability score View more details.

A high score means the brand (not the model) is less likely to have faults over time, according to CHOICE members.

Satisfaction score View more details.

A high score means CHOICE members are satisfied with the brand (not the model).

Service score View more details.

A high score means CHOICE members were happy with the support they received from this brand when they had a problem with their dishwasher.

Warranty (years) View more details.

Stated warranty of the dishwasher. You're still covered by the Australian Consumer Law regardless of the manufacturer warranty.

2
Country of origin View more details.

Where the dishwasher was manufactured, though parts may have been sourced from other places.

Germany
Availability View more details.

'Tested model' means you ought to be able to find this dishwasher in stores. We check availability every time we test, which is around 6 to 10 times a year. You may still find discontinued models on second-hand websites or in second-hand stores. 

With identical models, performance characteristics will be identical and the only difference will be something trivial such as colour, which won't have an impact on performance. 

Similar models are identical in most aspects except for a few, which means that a majority of their test results are identical so you can reasonably expect to get the same results from the model we tested.

Discontinued model
Price View more details.

The manufacturer's recommended retail price. Prices are often flexible, so shop around both online and in bricks-and-mortar shops for options.

$999
Running cost over 10 years View more details.

An estimate of how much the dishwasher will cost over 10 years for water and electricity if you wash a full load every day using a normal or auto-sensing cycle, based on 40c per kWh for electricity and $2 per 1000L of water. The greatest running cost will be the cost of detergent; this can vary significantly, so it's not factored in to these calculations. A dishwasher generally makes up around 2.9% of a household's annual energy usage. Look for the smallest number in this column so you aren't paying as much in the long run.

Program tested View more details.

The program we tested the dishwasher on. If a dishwasher has an auto program, we select it over the normal program. We do this because an auto or sensing program should be designed to give optimum results for every wash. You're probably also paying extra money for this feature, as the base model won't usually have it.

If there isn't an auto program we test on the normal program, as this is what our members tell us they use the most. If you see the phrase "to go", this means the dishwasher makes a guess on how long it will take. But this may change as it uses its sensors to go either shorter or longer; that's why we also record how long it actually took.

Normal 45°C
Place settings View more details.

The number of place settings a dishwasher claims to be able to fit. A standard place setting includes one of each of the following: a dinner plate, bread and butter plate, soup bowl, small bowl, small saucer, tea cup, drinking glass, knife, fork, teaspoon, dessert spoon and soup spoon (12 items in total). So a dishwasher that claims to have 15 place settings should be able to fit in 15 sets of standard-sized items of the above – that's 15 dinner plates, 15 drinking glasses etc (180 items in total).

14
Cutlery (Basket/Tray) View more details.

This describes what system the dishwasher has to clean the cutlery. These usually take the form of a basket, tray or both.

Yes/Yes
Colour View more details.

Where possible, we've listed the white model code and price. Most models are available in other colours, finishes or types – usually at a higher price. Stainless steel indicates any metallic or metallic-look finish; not all models are actually stainless steel. Where there is a 'Not applicable', the model is fully integrated and designed to match cabinetry (you'll need to buy fronts for these).

White
Tap connection View more details.

H or C: You can connect the dishwasher to hot or cold water. Connecting to hot water is likely to shorten the cycle time, but you may lose program versatility. You may need a tempering valve to connect to solar hot water, as the inlet temperature generally should not exceed 60°.

Cold: The product only has a cold tap connection, and the dishwasher heats the water itself (all dishwashers have a heater).

Cold
Maximum hot water inlet temperature View more details.

Where dishwashers accept a hot water source, there can be a cap on how high the temperature can be before it affects the hose or internal mechanisms. Usually this can be regulated by your heater, or a tempering valve can be fixed to the inlet if your water temperature is higher than accepted.

70°C
Dimensions (cm, H x W x D) View more details.

The dimensions listed are the smallest figures claimed by the manufacturer (we round up to err on the side of caution). It's best to leave extra space around the dishwasher for easy installation and air circulation.

82 x 55 x 60
Water inlet pressure (kPa) View more details.

This will matter if you have weak water pressure or a gravity fed water supply (tank supply).

50 - 1000

Child lock door View more details.

A useful safety feature which can help prevent curious little ones accessing the dishwasher tub.

No
Child lock controls
No
Child lock dispenser View more details.

This indicates whether the dishwasher has a child lock on the detergent dispenser. It's quite rare to have these.

Not tested
Anti-flood hose View more details.

Anti flood typically means a device is attached to the hose ending at the faucet which closes off the stream when a break is detected in the hose. (Asko claims its PEX hoses have the same level of protection.)

Anti-burst refers to a device located at the entry into the dishwasher which stops the flow of water into the machine if a break in the hose is detected.

We've not had a complaint about a flood from a dishwasher ​in a few years from our members, so it's likely either of these mechanisms would be satisfactory.

Yes
Delay start View more details.

Delay time, delay start or time delay is a feature that lets you program the machine to start the wash at a selected time in the future. You can load it with dirty plates and detergent and program it to start in the middle of the night (e.g. if you use off-peak energy) or during the day (e.g. if you have solar panels).

Yes
Time remaining display View more details.

This will show, usually in digital format, how long a program has to go. However, this may change during the wash, as the dishwasher uses sensors to detect just how dirty a wash is. It can be annoying to see the count get down to 5 minutes, then flip back up to 15 minutes as the dishwasher changes its mind.

No
Height adjustable basket View more details.

The top basket can sometimes be lifted into a different position, giving more height to dinner plates or pots to fit into the lower racks, or by lowering it you can fit taller glasses into the top basket.

Not tested
Easy-to-lift top basket View more details.

Look for height-adjustable baskets (usually the top basket) and removable or fold-down plate racks/tines for more versatility when loading. An "easy-to-lift" top basket means you can adjust the height without needing to completely remove the basket to change its position. Some models can be adjusted when fully loaded.

No
Fold-down plate racks View more details.

Fold-down or removable tines are useful for loading larger items like pots, pans and baking dishes.

Yes (1/2 of the tines)
Removable tines View more details.

Sometimes tines (the little spokes that hold your plates and crockery in place inside the dishwasher baskets) can be removed entirely to provide more space to put in larger items, typically pots and pans.

Not tested
Fan assisted drying View more details.

Usually dishwashers rely on thermal heat (the heat residing in your crockery after being exposed to high temperatures in the water) to dry the crockery via evaporation, but a fan can greatly assist in this drying process in some cases – the catch is that having a fan operating will cost you more in energy.

Not tested
Salt dispenser View more details.

A salt dispenser can be useful if you live in a locality with hard water (lots of minerals in the water that make detergent work less effectively). Adding salt to the dispenser means it can offset the results of the hard water. Hard water is not particularly common in Australia apart from places such as Adelaide, so not a must-have. Check with your local water utility about your water hardness condition.

No
Internal light View more details.

An internal light flicks on when the door is opened. Could be useful from either a safety aspect (you can see any knives pointing upwards when reaching in to take them out), or from a efficiency aspect (you can see if you've forgotten anything in the dishwasher).

Not tested
Auto-open door View more details.

Door automatically opens at the end of the cycle. This will generally mean a better drying score, because the heat exchange with the colder air acts to improve drying of dishes.

Not tested
Eco or bio wash View more details.

To wash more economically with less water, or at a lower temperature; about 50 degrees C is good for an enzyme-based detergent

No
Light or fast wash View more details.

For washing lightly soiled or rinsed dishes more economically in a faster cycle.

Yes
Delicates View more details.

Tends to refer to glassware or other type of crockery load that's fragile.

No
Pots or intensive wash View more details.

A commonly found feature in most dishwashers, suitable for pots and pans with dried-on dirt. Dishwashers often have "zones" suitable for these types of items, typically in the lower basket.

Not tested
Rinse only View more details.

Allows you to rinse (not wash) your crockery. May be useful if you're waiting for a full load to run your dishwasher but it's getting whiffy in the interim.

Yes
Auto or sensor program View more details.

Auto sensing or dirt sensor wash can be a useful feature as it claims to sense the dirt and adjust the wash to suit the amount of soiling on load in the dishwasher.

No
Half load View more details.

Half-load or load sensing half-load adjusts the water and program times for a much smaller load, while load sensing adjusts them according to the soil in the dishwasher. Both let you wash smaller loads more economically.

Yes
End of wash signal (audible/visual) View more details.

When the wash ends, a dishwasher will usually give an indication via an audible sound or a visual indication, or both. Some go to the point of playing a national anthem, which thankfully can be turned off.
