240v/3 wire to European 230/ 2 wire (coffee maker)
Hey all newbie here with an interesting question.
So II have a commercial coffee machine that is dual voltage that I want to use in Europe. The setup in the US for the 240v is changing to a 3 wire plug. How would I rewire it? (I'm not so concerned about the Hertz being different).
Seems it's two elements wired in series but where I'm getting stuck is that the European wiring only has 2 leads where as in the US it would call for 3?
I've done some research and it's hard to find much info on the conversion.
Any help with this is much appreciated.

You didn't leave an exact model..... just a generic link.
Does your machine have the 120.240v switch ?

Here is a link to the manual for the exact model Bunn manual for itcb brewer. And yes it does have the switch.

The bad news..... according to the instructions..... if it has the switch it requires a 4 wire hookup. That would be two hot wires, a neutral and a ground. The third wiring diagram is for a 230/240v machine with no switch.
That means it cannot be rewired for use in Europe. There may be a way of converting the heating elements internally but you'd need to contact the company directly for that modification.

I was thinking rewiring based on the straight 230v version but you may be right.
A call to the manufacturer would still need to be made to verify.

The link for the OP's model..... ITCB-DV....... with wiring is in post 3.
The wiring for the model with the switch is clearly listed there.

In your case you can use the coffee maker in Europe. Get a Euro style cord with single phase plug. Hook up the open end to the coffee maker. The black or brown hooks to L1 and the blue to L2. You also need to jumper L2 and N at the coffee maker connection board. The yellow/green of course to the earth symbol.

A...... thank you for mentioning a schematic. I didn't realize there was one at the end of the manual.
There is absolutely no way the model with the switch can be rewired to 230-240v use only.
The control section in there is running on 120vAC.
You would need the dedicated 230v model.
