Bosch Dryer: not draining
What is this symptom?
Is your Bosch dryer not draining properly? If it collects water instead of removing condensate, your clothes may remain damp. This issue often leads to error codes like E03/DR. Common causes include a clogged drain hose, a full condensation container, or dirty filters. Fortunately, there are DIY solutions you can try before seeking professional help.
Important Tips for Bosch Models
- Error code E03 specifically indicates a blocked or kinked condensation drainage hose on Bosch dryers and Bosch recommends inspecting and clearing that hose.
Possible Causes
Clogged or kinked condensation drain hose
How to Identify: Check for visible kinks or bends and disconnect the hose to inspect for blockages.
Part: Condensation drain hose
Full or improperly seated condensation container
How to Identify: If the dryer has a removable water tank, ensure it is emptied and seated properly; overfilling interrupts drainage. Community articles note overfilled containers can stop proper drainage. (åšä¸–家电
Part: Condensation container
Dirty filters or lint buildup blocking drainage
How to Identify: Check lint filter and condensation-area filters for lint and debris; cleaning improves flow.
Part: Lint filter / condensation filter
Faulty drain pump
How to Identify: No sound of pump operation and persistent drainage problem despite clear hose and container; water remains in drum.
