The site ladybird49 gave is NOT an online review site. It is the Which? site. They test all the machines themselves and collate reliability data from thousands of members.
There are several Best Buys at around £400, but only Bosch has top reliability. There are also several Don't Buys at the same price point - poor performers and poor reliability.
The most reliable brand is Miele - but much more expensive.
I haven't investigated thoroughly, but the latest Panasonic washing machines look very interesting. Energy rating A+++, and you can apply for a 5-year parts and labour guarantee, after purchase from a 'participating outlet'. see llink...
