What Does Error E13 Mean?
The Bosch dryer error code E13 signifies a malfunction typically related to an exceeded drying time or, in some models, a condensate or water level fault. This error results in the dryer failing to produce heat, causing the cycle to stop prematurely or run longer than expected. If you notice water accumulation in the base or container, especially in condenser or heat pump models, it's crucial to address these issues promptly to restore proper functionality.
Common Symptoms:
- Dryer cycle stops mid‑cycle when displayed error appears
- Dryer runs much longer than expected before error
- Possible water present in base/container on condenser or heat pump models
Possible Causes
- Maximum drying time exceeded due to restricted airflow, heavy load, or heating issue (medium)
- Condensate pump or water level fault on condenser/heat pump models (medium)
How to Fix Error E13
DIY Fix Check airflow and load size
- Turn off and unplug the dryer.
- Remove and clean the lint filter.
- Check exhaust vent and ductwork for blockages; clear if necessary.
- Ensure external venting is not kinked, blocked, or disconnected.
- Reduce the load size and run a shorter cycle.
DIY Fix Check condensate system (if applicable)
- If your model is a condenser/heat pump dryer, empty the condensate water tank.
- Verify it is seated correctly.
- Inspect condensate pump and hoses for clogs and clean them.
- Reassemble and restart a drying cycle to see if error clears.
Technician Only Test and repair key components
- Measure airflow and resistance through heating element and thermistors to ensure proper operation.
- Test condensate pump motor and water level sensor (if condenser/heat pump model).
- Inspect control board for error storage or defective relay circuits.
Parts needed: Heating element, Thermistors/temperature sensors, Condensate pump, Water level sensor/float, Control board
- If after basic cleaning and load changes the error persists
- If you detect water in a place it shouldn’t be on your condenser/heat pump dryer
- If internal electrical component tests indicate faults
