No one really loves doing the dishes. The great news is that a modern dishwasher uses far less water and energy than washing dishes by hand, particularly if you run full loads.
"Buying the right washer can make a huge difference to your daily dishes," says CHOICE whitegoods expert Ashley Iredale. "On the other hand, a mediocre model can cause more hassles and have you picking food scraps off the forks after every wash, and no one wants that."
Ashley takes 'doing the dishes' very seriously.
In our latest dishwasher reviews, our lab experts tested popular new models from brands including Smeg, Fisher & Paykel, Bosch, Miele, Dishlex, LG, Westinghouse, Kogan and many more.
After days of 'doing the dishes', they uncovered some impressive cleaners and some serious under-performers.
How do we test them? Well, it's a dirty job that involves crusty crockery identically stained with foods such as oats, egg, spinach, baby cereal and more – left out overnight, then washed and analysed (learn more about how we test).
To help you buy right and avoid costly mistakes, here are the models that scored lowest in our latest lab tests.
Lowest rated dishwashers
Omega ODW101W: Poor performer.
- Price: $599
- CHOICE Expert Rating: 58%
- Washing score: 63%
- Drying score: 35%
The worst performer in our test overall, this half-size benchtop model does about half the job we'd hoped for. It earned the lowest washing score of all models and performed very poorly for drying too, meaning you'll be reaching for that tea towel once its long cycle has finally finished.
On the upside, the Omega is cheap to run (which is good because you might need to run it twice to get the wash you want). Just don't let this model put you off benchtop units altogether – Ashley says other smaller models do perform well.
"Due to their size, some people assume these pint-sized plate-cleaners deliver poor wash performance at best," says Ashley. "But we've seen some benchtop models that punch well above their weight and even outperform many full-sized dishwashers." Read our full Omega review
Kogan KAGDWS15CTA: Must dry harder.
- Price: $900
- CHOICE Expert Rating: 67%
- Washing score: 76%
- Drying score: 32%
To be fair, this basic Kogan dishwasher does a very decent job of washing dishes. It just leaves them sopping wet afterwards, with the lowest score for drying in our current test.
Blanco BDW8345X: Energy guzzler.
- Price: $999
- CHOICE Expert Rating: 67%
- Washing score: 69%
- Drying score: 63%
This dishwasher scored just OK in our lab testing, but you should know there's plenty of better performing models out there for the price point. It's also not very energy efficient, scoring one of the lowest ratings for power consumption per place setting, which makes it more expensive to run. Read the full Blanco review.
