Most and Least Reliable Dishwasher Brands

Our predicted reliability ratings are based on data about nearly 70,000 dishwashers, spread across 28 brands. All of the machines in our survey were purchased by CR members between 2014 and 2024. They include models from popular names such as Bosch and Samsung, lower-cost options like Ikea, and high-end companies such as Miele and Thermador. We combed through the responses for any reports of performance problems or breakdowns to predict how reliably a dishwasher from a given brand will hold up in its first five years of service.

The results are clear: No brand is completely immune to problems, and a brand’s quality can vary over time because of changes in design or production. But certain brands make dishwashers that are much less likely than others to have problems in that first five-year time span. Using our reliability ratings, you can improve your chances of ending up with a dishwasher that will last a long time.

CR members can read on for a summary of the brands that we expect to be the most reliable, as well as a warning about the five least reliable brands in our surveys.
