If the plug came with the machine, then I would say no…. But in the event that someone has fitted the wrong plug….
What is the rating of the coffee machine?
There should be a sticker or plate with the details. It will be in W or kW
If you can’t find it, send a message with the make and model number of the machine, and we can work it out.
Take that value… it should be in thousands. If kW, multiply by 1000 to get to thousands range.
Divide by your mains voltage. In Uk, we take it as 230V, This gives Amps.
Compare this Amps with the supply. Ie, if it’s below 13A, then yes, you can try changing the plug… if over 13, you can’t.
