There isn't really much distinction between the mainstream 'brands'. Like modern cars they're mostly built from a small range of parts-bins:

Electrolux Group: AEG, Electrolux, John Lewis, Tricity-Bendix, Zanussi

Indesit: Ariston, Creda, Hotpoint, Indesit

Candy: Candy, Hoover

Bosch: Bosch, Siemens
