Grainfather plug stuck in the socket

[jceg316]

I did a couple of brews this weekend, when I was packing up on Sunday evening my Grainfather mains plug was stuck in there, I think it welded itself in there as it's not budging.

I had to replace the lead it came with a couple of months ago with a new one as the original plug was getting an odd white coating over it and the wall socket I plug into it was getting an odd yellow colour. Approximately 10 brews on this happens with the new one. This was supposed to be a heat tested IEC cable.

Along with a new kitchen plug, I also need a new cable, any recommendations? I bought a Grainfather to avoid this sh#t happening.

Why did this happen? Did some reading and there's a loose connection somewhere either in the plug or behind the socket. Does this sound right? I'm in a fairly new build (2011) and plugs seem fine, I'm thinking a faulty plug.

No expert at all but seen this...sounds like an overload...

There's a loose connection definitely and quite possibly on the socket due to discolouration when the outlet is overheating.
This being a recent build should be on a ring main and rated at 30/32 amps at the circuit board.
Come across quite a few in my time but easily rectified with a new socket though would check for burning on the cables by unscrewing the faceplate from the after it's been isolated at the fuse board.
Get a quality replacement but be sure to check the polarity connections as some are opposite to others and can cause issue when reconnecting due to cable length.
The reason it's showing now is the prolonged use of high current through the outlet.
Use a branded one like this

Thanks for the replies. I was speaking to my dad about this who is an electronics engineer (or electrical engineer, I can never remember which one) and he says pretty much the same thing about a loose connection, but specifically it can be caused by dirt on the pins, which I imagine is the culprit. He's coming over to put in a new socket.

I had a similar problem of an overload on my burco boiler which burnt through the live lead to the thermal cutout. It's a twin socket and we has the washer and dryer on as well as the boiler. Socket really hot too. Just pulled too much current. Anyway bought a new thermal cutout and fixed the boiler today.
Now got two boilers as I bought a replacement.
