Sorry for the delay in replying
Firstly, yes... sorry, a tumble dryer. Sited in the hall, where originally we had one of those wound extensions running into the kitchen under a door the we keep closed behind the dryer.... and into a socket in there - that socket was only installed maybe 3 years ago... with the new kitchen so shouldn't have been an issue. Though I see now that the wound extension may have been. Once that burned out, we bought a length of cord with a socket on one end and a plug on the other from an electrical shop and ran it down the hall to an older socket. This was the one that melted today. The plug from the dryer does get hot but it was the extension plug in both cases that melted.
Now.. one thing worth mentioning is that I moved the dryer to hoover yesterday and it may have been put back too close to the wall... possibly... I am not certain as hubby pulled it out when the plug got burned so not sure where it was :-\
