Plugged into wrong Voltage 220V.

Plugged into wrong Voltage 220V.

Good afternoon, I accidentally plugged my Keurig machine into the wall without a transformer. The voltage here is 220V. Do I need to buy a Keurig transformer to replace or how can I fix it? Please help. These Keurig was given to me as it was my grandmothers best coffee maker. She lost her battle to COVID-19 this past year so it is very valuable to me. Thank you !
