Bosch Tumble Dryer Error Code E03 – Meaning and Possible Fixes
Bosch Tumble Dryer Error Code E03
If your Bosch tumble dryer displays Error Code E03, it usually indicates a problem with the condensate drainage system. This means the appliance is unable to pump water from the condensate reservoir or drainage system.
Bosch condenser and heat pump tumble dryers collect moisture removed from clothing as water. This water is normally pumped into the condensate container or discharged through a drain hose. If the system cannot move the water correctly, the dryer may stop the cycle and display the E03 error code.
