Each burner has its own ignitor, which creates several sparks per second when the burner knob is placed into the "Lite" or "Light" position. When in this position, the spark module sends an electric current through the ignitor, which creates the sparks.
If water gets into an ignitor, it will cause a short. The ignitor responds by clicking excessively. To prevent this from occurring, avoid using an excessive amount of water to clean the stove top and use a dry cloth when cleaning the ignitors.
The clicking is not harmful to the range and will stop when the water evaporates from the ignitors. The evaporation process may take several hours, though, depending on the conditions inside your home and the amount of water inside the ignitors.
Although the ignitors will stop clicking on their own as soon as the water evaporates, there are two steps to take to expedite the evaporation of the water. First, set the oven to 350 degrees Fahrenheit and allow it to run for at least 30 minutes. Second, position a fan so that it is blowing directly onto the burner knobs, allowing air to flow through the underside of the stove. The added heat and passage of air will greatly reduce the amount of time needed to evaporate the water.
