The present invention provides a drum washing machine, capable of enhancing washing performance while inhibiting increase of power consumption. The drum washing machine (1) includes: a driving part(30), capable of operating in a uniaxial driving form and a biaxial driving form, wherein the uniaxial driving form is a driving form that enables the drum (22) and the rotating body (24) to integrally rotate at a same rotating speed, the biaxial driving form is a driving form that enables the drum (22) and the rotating body (24) to rotate at different rotating speeds; a heater (60) configured to heat water stored in the outer drum (20) for washing; and a control part which at least performs washing operation of a first washing mode and a second washing mode. In a washing process of the first washing mode, the control part enables the driving part (30) to operate in the uniaxial driving form and also enables the heater (60) to operate. Further, in a washing process of the second washing mode, the control part enable
