I want to buy a vintage European coffeemaker with a heating element (220V 50hz) and do whatever is necessary to get it to plug safely into a standard two-prong or three-prong wall outlet here in the USA.

I've read some answers here about converting a 220V appliance to 110V, but the answers assumed more knowledge than I have about this subject, which is almost zilch :(

Are there step-by-step instructions anywhere for doing this sort of conversion? Do I have to take the machine apart to get at its insides, or can the work be done on the wire and plug outside the machine?
Thanks

You can change the heating element inside to 120 volt, thou not sure where you will find the exact element to fit that is 120 volt.

The best you may do is to set up a 120 volt to 220 volt transformer, so you do not need to take the coffee maker apart.

You may be better served by bringing the unit to a small appliance shop that may have the parts to change the unit to 120 volt properly.

Thanks for the information and the sound advice. May I follow up on the first item, changing the existing heating element to 120V. Not how to do it, but what the negative effects would be if it were left in place. If left unchanged, will the heating element not work at all, or be a fire or schock hazard, or simply work less efficiently?

Thanks!

If you try to operate the 220 volt maker at 120 volt the element may only get warm, certainly not hot enough to make the coffee maker work properly.

Thanks. Your answers have been very helpful. You've steered me away from a mistake :)
