If your Bosch dryer is leaking water, start with the most likely causes and work down the list. A damaged or loose fill hose that supplies the steam system often causes leaks outside the cabinet, so inspect the hose for cracks, holes, and tight fittings first. If water appears inside the drum or you see misting, check the steam nozzle for visible damage and replace it if it is cracked or clogged. If your model is not a steam dryer, look for other household leak sources before assuming the dryer is at fault. A failing steam generator is a common interior source and will leak if its housing is cracked. Also check hose connectors and rubber washers and tighten fittings to stop leaks underneath the machine. Less commonly, a cracked water inlet valve inside the cabinet will let water into the dryer and should be replaced.

01 - Bosch Dryer Fill Hose
A water leak that is coming from outside the dryer cabinet may be caused by a damaged fill hose. Inspect the hose for small cracks or holes and confirm the hose is secured firmly to the inlet valve. A damaged hose will need to be replaced with a new one. If needed, install new rubber washers at the ends of the hose for a water tight seal.

A water leak inside the dryer drum may be caused by a faulty nozzle, the component used to spray the hot mist. Inspect the nozzle for any cracks or signs of visible damage and replace the old nozzle with a new one if required.
A non steam dryer is not connected to water and will not cause a leak. Look for other sources of leaks.
