There are four Bajjar Kurehits (Cardinal Sins/Conduct to refrain from) that indicate that you have broken your Amrit and they are as follows: sex outside of marriage, cutting your hair, eating Halal meat, and smoking or use of tobacco in any form. If you have done any of these things and you are Amritdhari (Initiated Sikh), then you have to go Pesh (Confess) in front of Panj Payare (Five beloved ones) and take Amrit again.
