I was called to a job yesterday and found this burnt socket and plug supplying a dishwasher in a cupboard full of old newspapers …..
TOUCH switches, sockets, Lamps, Consumer unit to see if they are HOT
SMELL things for a burning or even a “fishy” smell ( you will know it when you smell it!)
LOOK to see if there is any scorch marks/blackening
LISTEN for crackling, buzzing or fizzing
TASTE a cup of tea for a job well done
Most important of all , use your COMMON SENSE and call an electrician if you find ANY of the above.
