There may be the following reasons for water seepage in the kitchen exterior wall:

1. Waterproof layer is damaged: the waterproof layer of the kitchen exterior wall is damaged or aged, which will lead to water seepage.

2. Water pipe leaks: If the water pipe inside the kitchen leaks, it will also cause water to seep from the wall.

3. Rain infiltration: In rainy season or heavy rain, rain will penetrate into the kitchen wall through windows and gaps.

4. Building structural problems: If there are structural problems in the building itself, such as cracks in the wall and settlement of the foundation, it may lead to water seepage.

5. Improper cleaning: When cleaning the kitchen with detergent, if you accidentally spill the detergent on the wall, it will also cause water seepage.
