Oh, thought I should add that I wash nappies in mine too. I also use it for DH's work clothes (he's a shearer). It has different cycles. Heavy duty, & every thing. I usually put nappies on the heavy duty cycle, but put it on slow spin, so it has a half hour soak & extra rinse, but spins gently.
Mine also has a timer for 1 3 & 9 hours.
