If the wires are shorting out you would either experience a power interruption, circuit breaker or fuse blow, and/or a smell of some sorts. If this is under warranty I suggest you turn it in for a new one. On the other hand, remember it is a percolator device and when water is heated to the desired temperature the action is for the hot water to rise and flow over the basket containing the coffee grounds. Percolation makes a popping sound, at that is a normal condition.
