Water, power disconnect or at least be sure they are off. Drain as much water as possible from cabinet, rest machine on back (any extra water should stay inside). Underneath is a metal floor plate secured by two 'star' screws. remove this, it will have an earth wire attached. The pump is now at top left. Handy hint - when you have done what you have to do - be very sure you have replaced that pump cover with all three plastic lugs in their slots, otherwise you get a lovely paddling pool effect!
