sounds like a radial circuit (15A fuse wire straight from CU to socket). As a 15A fusewire pops at about 8xFLC (was it the correct lump of fusewire, or a bit of wire nail?!) I'd wager the large inrush load has melted a bit of the copper cabling at either the CU termination, or the socket. Check the live, neutral and earth.
Also, consider replacing your re-wireable CU with a nice MCB CU with RCBO.
