The pump is behind the lower plastic plinth cover at bottom of the front of machine. Remove plastic panal. On some machines there is a steel bottom on the machine & if so, then the only way to gain access is remove the front panal of the machine.
If you are lucky enough to have a machine that is open underneath, then the pump can be removed from underneath by lying machine on it's back, if not.......
The front panel is fixed by: 1xscrew behind soap dispenser drawer handle--remove drawer & then lower r/h screw, two screws at bottom of the front-panel in the fold/step, two screws holding door lock to front panel.You will also need to disconnect the door-seal from the panel-this is retained by a sprung wire. Once front is removed - it's easy.
Hope this helps.
