Most and Least Reliable Dishwasher Brands

No brand is completely immune to problems, and a brand’s quality can fluctuate over time due to changes in design or production. But our survey reveals that dishwashers from certain brands are significantly less likely than others to experience problems during their first five years of use. Using our reliability ratings, you can increase your chances of choosing a dishwasher that will last a long time without expensive repairs.

Our predicted reliability ratings are based on data on 92,994 dishwashers across 28 brands. All of the machines in our survey were purchased by CR members between 2016 and 2026. They include models from popular names such as Bosch and Samsung, lower-cost brands like Ikea, and high-end companies like 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.

According to our survey, around 20 percent of the dishwashers owned by our members have broken down or stopped working as well as they should. A dishwasher that’s no longer cleaning properly is the most frequently reported problem, occurring in 8 percent of the dishwashers. Other common problems include the dishwasher not drying properly (7 percent) and not draining (6 percent).

CR members can read on for a summary of the brands we expect to be the most reliable, as well as the four we expect to be the least reliable, based on our surveys. Members can also explore our comprehensive dishwasher ratings for over 130 models, which are based on extensive testing of washing, drying, noise, energy consumption, and ease of use, along with our survey results.
