HI MARK
TO DO THIS JOB IS VERY SIMPLY.
I LEAN THE MACHINES BACK BUT YOU WOULD BE BETTER LAYING IT ON THE RIGHT HAND SIDE LOOKING FROM THE FRONT.
THE PUMP IS PUSHED IN SO IT HAS TO BE PRISED UP A BIT TO RELEASE IT, OR THE OTHER WAY IS UNDO THE THREE SCREWS AND ID PULLS TOWARDS YOU.
THE PUMP IS THE ONE WITH THE GREY CRINKLY HOSE CONNECTED TO IT.
THE PUMP IS AT THE FRONT UNDER THE DOOR ON THE BASE
WE CAN SUPPLY A PUNP IF YOU WISH.
DISCONNECT THE MAINS BEFOR DOING ANY WORK ON THE MACHINE.
HOPE THIS HELPS.
