Bosch Washing Machine Error Code E38 – Meaning and Possible Fixes
Bosch Washing Machine Error Code E38
If your Bosch washing machine displays Error Code E38, it usually indicates a problem with the pressure chamber system. The pressure chamber and pressure hose are used to measure water levels inside the washing machine during the wash cycle.
Bosch washing machines monitor water levels by measuring air pressure through a small chamber connected to the tub. If this chamber becomes blocked or the pressure signal cannot be read correctly, the appliance may stop the cycle and display the E38 error code.
On some Bosch washing machine models this error may also appear as F38.
