[QUOTE="boltonsparky, post: 500198, member: 4678"] If there isn't overload loose connections is the usual cause of things melting/cables burning. Any damaged cables will need repairing properly as failure to do so will again cause high resistances and resultant heat. A 13a plug top fuse won't blow for a surprising amount of time if it's only just overloaded. I've seen well melted plugs with the 13a fuse still intact. Equally your MCB will be a 32a most likely (although could be a 20a or 16a) so it would need a load of 7.36KW before being overloaded and even then tripping time would be slow. Any socket outlet that is genuine and rated at 13a should be ok for use up to a 13a load however some wiring accessories are of dubious quality these days, they don't make them like they used to. What state is the plug top for the dishwasher in, is it a moulded one? There could be a fault within the dishwasher causing an excessive load. [COLOR=#c0392b]"These sockets then run off the kitchen ring via a wall socket behind the rear cupboard panel (we can't access this without removing the appliance)" [/COLOR]this sounds suspect as a kitchen fitter masterpiece and doesn't sound right to me although I don't fully understand what you mean by it. You may have a spur off a spur so the cable is overloaded hence the melting. [/QUOTE]
