The pre-charge current dissipates power in the resistor. Each successive pre-charge adds more power so if the resistor has not cooled between operations then the temperature will rise. Frequent pre-charge operations will cause the temperature of the resistor to increase, potentially to the point where the resistor overheats and fails.
