Here's how we test the latest washing machines.
Our method of testing washing machines has changed. We used to test washing machines on a "full load".
So if a machine had a maximum capacity of 7kg, that’s how much we stuffed into it. As our past tests found, this wasn't always easy to do – and we also know this isn't what people do at home.
We now test washing machines using a smaller (3.5kg) load. Our research shows this is about in the middle of the range of amounts that most people wash, whatever the size of their machine.
We retested several machines from previous tests with a 3.5kg load. We found:
We've also revised our rating scale so that dirt removal is the most important part of the scoring. Dirt removal now accounts for 50% of the overall score (up from 40%). Rinsing accounts for 20%; and gentleness, water efficiency and spin efficiency are each worth 10%.
We recommend front loaders that score at least 80% overall and 80% or better for dirt removal. If you prefer top loaders, we recommend those that score at least 65% overall and 70% or better for dirt removal.
Our test is based on the standard AS/NZS 2040:1998, and was completed using machines filled with 3.5kg loads.
Overall score is based on:
