Bosch Tumble Dryer Error Code E29 – Meaning and Possible Fixes
Bosch Tumble Dryer Error Code E29
If your Bosch tumble dryer displays Error Code E29, it usually indicates that the appliance has detected a problem with the moisture sensing system.
Bosch tumble dryers use moisture sensors to determine when clothing has reached the desired dryness level. These sensors measure the electrical conductivity of damp clothing and send this information to the control system. If the dryer is unable to receive accurate readings from the sensors, the appliance may stop the cycle and display the E29 error code.
