The 223 and 270 error code are telling us furnace cannot light because the pressure switch is not closing.Make sure the intake and exhaust vents are not blocked by snow, ice , spider weds or anything and that condensate drain is not frozen or backing up.

Were you able to check and make sure intake and exhausts are clear?
