The desiccant is designed to absorb excess moisture, and prevent it from making its way into the gap between the glass panes. As it becomes saturated, the desiccant will not be able to absorb moisture, and the amount of moisture between the panes will rise.
A swell of moisture forming between the aluminium strip and the seal is often the first indication.
