Who removes Election Commissioner?

Election Commissioners hold their office during the pleasure of the President, subject to any law made by Parliament in this regard.Article 324 says that the Chief Election Commissioner shall not be removed from his office except in like manner and on the like grounds as a Judge of the Supreme Court and the conditions of service of the Chief Election Commissioner shall not be varied to his disadvantage after his appointment. Therefore, the removal of election commissioners differs from that of the Chief Election Commissioner.
