To Switch Off

I am aware that I have to unplug the electrical cord from say an electrical kettle (it could be any appliances) before I pull the 3 pin cord from the electrical switch on the wall.

To Switch On

I have to insert the 3 pin cord into the socket in the kettle before I insert the 3 pin cord into the electrical socket on the wall. Do I have to insert the 3 pain cord into the electrical socket VERY VERY QUICKLY (WITH SOME FORCE)to avoid the blue light/flick?

Rarely I have seen the blue flick. How do I completely eliminate the blue flick on the electrical socket on the wall (for switch on and switch off)?

Call an electrician and have them assess your receptacles and possibly replace them. If there is a lot of arcing, they need maintenance.

If you see a blue flick when your plugging your kettle in it is just the load of the kettle when plugged in. If you have a way to shut off the kettle before plugging it in do that. The cheapest fix to me sounds like getting a kettle with an on off switch. Sorry If I am misunderstanding your problem but my answer to your question based on my understanding is most appliances will have a small arc when on and plugged in. Also if your receptacles are older the appliance may be loose in the receptacle and the receptacle should be replaced.

This is generally a sign that the receptacle is worn out. Replace with similar one. If it is AL wiring, make sure you use an AL rated receptacle; they are usually around $6.00 compared to a standard receptacle that is about $2.00 each or less.

Please help.

Which is the proper way to plug the electrical cord onto the wall socket?

(to avoid a blue flick)

Do I plug in the cord into the coffee maker before I plug the cord on the wall?

Do I unplug the cord from the wall before I unplug the cord from the coffee maker?


Here is the reply from the makers of the coffee maker.

Dear Consumer,

There is no power switch for this appliance. It powers on and starts perking once it is plugged in. After brewing, the appliance will stay on and keep the coffee warm until it is unplugged.
