No, UK washing machines do not work with US electricity without the use of a voltage converter or transformer. The electrical systems in the United Kingdom and the United States are different. In the UK, the standard electrical voltage is 230 volts at a frequency of 50 hertz, whereas in the US, the standard voltage is 120 volts at a frequency of 60 hertz.
Using a UK washing machine in the US without a voltage converter could lead to damage to the appliance or even pose a safety hazard. If you want to use a UK washing machine in the US, you would need to ensure that it is compatible with the US electrical system by using a voltage converter or transformer. These devices can adjust the voltage and frequency to match the requirements of the washing machine.
It's worth noting that even if you use a voltage converter, you should also consider the physical compatibility of the appliance. The plugs and sockets used in the UK and the US are different, so you may need an adapter to connect the washing machine to the US power outlet.
