The most common reason for a double-glazed unit failing is that the desiccant in the unit becomes saturated. The desiccant absorbs moisture and stops it from getting into the glass panes' gaps. When it is saturated the desiccant is unable to absorb moisture and the moisture between the panes will grow.
The formation of moisture in the gap between the strip of aluminium and the seal is typically the first indication. It is important to remember that this isn't an easy fix, and the best option is to replace the entire unit.

If the condensation is inside your window, it could be a sign of an issue. This is because the condensation in your window means that the seals have failed and water can get in between the glass panes.
This is usually caused by poor ventilation. If there is no air circulation the warmth inside your home is sucked up and this can cause moisture to build up. This is especially common in bathrooms and kitchens where there's lots of humidity and moisture in the air. If you have a misty double glazed window, it's essential to check your ventilation and reduce the humidity levels within the room to stop condensation from forming.
The failure of double glazing seals could also lead to increased energy costs. This is because your heating system will need to work harder in order to keep your home warm, and this will increase over time. Double glazing that leaks can allow cold air into your home which makes it feel colder.

Faulty installation can cause the seals on the window panes to crack, allowing moisture to get in between. This will then eventually corrode the spacer bar made of aluminium and result in the sealant inside the unit degrading. The anti-moisture grains within the spacer bar may be saturated by water and stop working as efficiently.
