I require a replacement part for my Swan slow cooker Model No 00469 115watts. This is a small electrical connection which is held in place by a small screw, on outside of inner aluminium casing.It can only be viewed after removing handles and lifting bowl out. Measures about 16mm square by 4mm thick and has two terminals attached to it for spade fittings. I would appreciate anyones help. Many thanks Alexander Lees.
