In Germany, there's Stiftung Warentest ("Product Test Foundation"), with the best domain: https://www.test.de :-D

They are a non-profit with a 55-year history, a stellar reputation and a track record of calling out any issues found. Their test results are broken down in a detailed way, and they have useful graphs like price vs rating. They actually buy their products instead of taking prototypes or commerical samples. They report the real-world, online consumer prices. Their own prices are reasonable (8€/month for all access, incl. PDF downloads).

Washing machine tests are actually one of their staples.
