how can i fix my electric dryer?

i bought the following dryer from Home Depot and moved to Nigeria with the equipment - Admiral®\r\n6.5 Cu. Ft. Electric Dryer, Model AED4475TQ, store SKU 750491, Internet/Catalog SKU 100604046 -however, it has not worked because nothing happened after it was connected to a 15 amp socket.

do i need add or modify anything before it can work in a 220-240v environment?

thank you.
