Electric socket not working

Apodemus

Just glad its sorted and that you came back to update everyone!

A dishwasher should not be supplied through an extension lead. Likely the lead, socket-outlet and/or plug top are burnt out. This is a fire hazard.

Why is it? Everything above is 13A rated, but a dishwasher is 10A max.

I know, there are very poor quality extension leads, but that's another story.

Really? Mine is effectively supplied through an extension cable, except for the fact that one end is hard wired into the type of switch that was shown above. However the dishwasher just plugs into the other end and there have been no issues for 10 years and no one has ever raised it as a problem, either the original electrician or the person that installed the replacement dishwasher.

are you one of these people that looks at everything and then says, with a sharp intake of breath, that’s going to be expensive?

Risteard

Extension leads aren't intended to supply large loads for extended periods. Also ratings for fully unwound and coiled up are different. Also they are not designed for permanent use - if you need power permanently in one place then have a socket-outlet installed. (And not two appliances in a double socket-outlet either as they are not designed for two heavy loads.)

Mine (Bosch) is the same.
The maximum current draw is 10A and this is only when the water is initially heating up. After that, it drops down to 3 amps for the remainder of the washing cycle. Even when it's heating up for the drying cycle, it's only using 7 amps.
If I was to use it plugged into a 13A rated extension lead, at the very most it would only be drawing 75% of the current that the lead was rated for and for the vast majority of the time, it would be less than 25% so provided that the extension lead is of good quality and unwound fully, I can't see why it wouldn't be safe to use.

But what is a large load? and what is an extended period?

Cool! It takes a brave person to come on and admit such an oversight. Good job we are kind, thoughtful and considerate folk on here who wouldn't DREAM of bringing this back up at every conceivable opportunity...

They haven't got it supplied through an extension lead. They used an extension lead to check if the fault was with the socket or the appliance.  The washer worked when plugged into the extension hence the question

 do sockets themselves fail?

Expecting obvious physical damge there is about a 0.00000001% chance of that.

this is strange, I've replaced hundreds of sockets that have failed?? have I just bizarrely come across the 0.00000001%?
of course they fail. and a lot more often than you think!

I think "hundreds" is a huge OVERestimation too.

Switched sockets fail far more often, but in this case it's unswitched one.
