Isolated mains.Took off front panel(2screws).Took off control panel (2screws below panel each side, 1screw each side sunk into underside of panel) ease panel slightly downward and pull forward.You can now release the facia of panel by undoing the 2 screws in top of facia and 2 in each side plastic moulding.This allows the facia to move to access the screws holding the switch in place.Pull off the spade connectors,remove the switch,replace and reverse the procedure to reassemble the parts making sure you fit the correct size screws to each part.Reconnect mains and its job well done.I didn't have the appliance model No.so I took the numbers on the switch,did a search on appliancepartspros.com.and they came straight back with current replacement ,thanks guys!
