Unplug machine , remove lid, remove all screws around edge of back panel and the 3 large ones in centre that hold the drum shaft, move the panel back and slide new belt on drum and motor pulley, belt is elastic type and very tight, drum will drop down, refit back panel to centre drum shaft with the 3 large screws then hoist up the panel stretching the belt till all back panel screws line up and refit, best of luck cheers
