Where do I plug it in?

A washing machine in the museum at Anne of Cleves House in Lewes.

Powered by muscles only, you had to put the clothes in and rock it backwards and forwards.

Thomas Paine lived in Lewes, and his house can be seen from the outside at least (for some reason I can't get it to upload to blip extras), and the hotel where he discussed his theories, the White Hart, is still open.
