Any help appreciated. I keep the tumble drier out in the shed ( don’t ask) and run a proper outdoor cable to it when its used. Noticed the other day when taking the plug out both it and the socket were very hot. Cable to the dryer about 10 m is stretched out , not coiled and the drier only a few months old. Any ideas? Suffice to say socket now not being used. Electrician the obvious answer?
