Bosch Dryer: leaking water
What is this symptom?
If your Bosch dryer is leaking water, it’s likely due to improper moisture handling. This issue can manifest as puddles under the unit or condensation around the vent. Common culprits include clogged vents, improper leveling, or faulty components. Addressing these issues promptly is crucial to prevent damage and ensure optimal dryer performance.
Important Tips for Bosch Models
- Bosch condenser and heat pump dryers have a condensate tank that must be emptied after every cycle; improper installation height for drain hose (>100 cm) can lead to leaks.
Possible Causes
Clogged or obstructed vent/exhaust duct causing condensation buildup
How to Identify: Water at vent outlet, moisture inside duct, slower drying times, visible lint accumulation, water puddling under or near vent
Part: Vent hose/exhaust duct
Improper leveling or placement
How to Identify: Dryer sits unevenly or on soft/flexible surface; water pooling on lowest side
Part: Dryer feet/placement
Full or damaged condensate tank or drain hose (condensing/heat pump models)
How to Identify: Tank not emptied, cracked, water leaking externally, kinked or damaged hose
Part: Condensation tank/drain hose
Faulty or leaking water inlet valve
How to Identify: Water leak from valves or hoses at rear; cracks in valve body
Part: Water inlet valve
Worn or defective door seal/gasket
How to Identify: Water at door perimeter, visible seal wear or damage
Part: Door seal/gasket
