Should you turn off appliances at the socket when not in use?

Wall socket Ideally yes you should turn off certain appliances at the socket when not in use. If the wall socket doesn’t have an on off switch it would need to be unplugged instead.

Electricity still runs inside an appliance even if it’s switched off. If electricity is present, there is always the possibility of something overheating or shorting out. However, it is far more likely that if something was to go wrong it would be whilst the appliance is in use.

Where does electricity run inside an appliance?

With an appliance plugged into the wall socket electricity runs first through its plug and mains cable. After that it enters the appliance and goes through a mains filter (suppressor). Then on to the on off switch. Theoretically it should stop there until the on – off switch is activated. But it is possible for power to also go to the main PCB, the door lock, control panel.

In the past I’ve known mains suppressors on some washing machines short out and explode (like a firework – but no fire). The washing machines were not in use at the time. To be fair that was a long time ago and on a specific brand of washing machine. But this shows the possibility of something shorting out with the appliance not running.

Recent examples of fires with appliances not running

This article was inspired after reading a recent media article where a tumble dryer had apparently, “caught fire” whilst left plugged in. From the pictures that I could see though it appeared that the fire incident was small, and confined to the wall socket and plug. Someone also added a comment to one of my articles saying that their tumble dryer caught fire whilst left plugged in but not running.

Reduce Risk

Is it essential to turn off appliances at the socket?

Many millions of electrical goods and appliances are left permanently plugged in. It’s extremely rare for anything bad to happen. But if it’s not really any trouble to turn off the wall socket or unplug the appliance when you’ve finished using it – then why not?

This is what I do

My own washing machine and tumble dryer are in our garage. They are very much out of sight. We always try to remember to turn both of them off at the socket when we have finished using them. Fortunately, this is pretty easy as both sockets are easily accessible just above the appliances..

Our dishwasher on the other hand is a built-in appliance in our kitchen. The socket for the dishwasher is located behind a load of pots and pans in the bottom of a cupboard and behind a back panel. It is accessible, but only with a fair amount of effort. Therefore unfortunately we never turn it off at the socket.

If we ever did have a fire we would no doubt seriously regret that. But as you can imagine it is a lot of extra messing about with an appliance that is used virtually every day. We all have to make these kind of judgement calls. The risk is not great, but is undeniably there.

So if it is easy to turn off the appliance at the wall socket then why would you not? If it is quite difficult then it is understandable that you don’t. But is it possible to rearrange things to make the wall socket more accessible? With my own dishwasher I could, with a fair bit of effort, rearrange everything so that the microwave is plugged into this socket and the dishwasher into a separate one above the worktop. This, is something I need to do.

    Hello Richard. As you can imagine I’ve seen many very poor examples, with mains sockets directly underneath parts of the plumbing that could easily leak and run water straight into the socket. But in many houses some thought has been given to the position of wall sockets that the builders know will be used for a washing machine. They may still have the wall sockets behind the washing machine or inside a cupboard, but they usually install a separate switch above the worktop somewhere that is easily accessible and often even labelled.

    But generally speaking, especially in older houses, wall sockets are just badly placed and totally inaccessible far too often. Often tradesmen will have an overriding goal of what is easier for them. A perfect example of this is in my son’s brand new house where the mains socket for the washing machine was attached to the 1 mm thin ply board at the back of the under sink cupboard. As soon as you start pushing and pulling on the main socket it just came completely loose. I had to relocate it to the side of the cupboard and was able to screw it firmly into a proper surface.
