Bosch Washing Machine Error Code E31 – Meaning and Possible Fixes
Bosch Washing Machine Error Code E31
If your Bosch washing machine displays Error Code E31, it usually indicates that the appliance has detected a problem with the water level monitoring system. Bosch washing machines use sensors to measure the amount of water inside the drum during the wash cycle.
If the washing machine detects that the water level is higher than expected, or that the water level system is not responding correctly, the appliance may stop the cycle and display the E31 error code.
On some Bosch washing machine models this error may also appear as F31.

What the E31 Error Means
The E31 error code generally indicates that the washing machine believes there is too much water inside the drum or that the water level monitoring system is not working correctly.
Bosch washing machines rely on a pressure sensor to monitor the water level inside the machine. If the appliance detects an abnormally high water level or receives incorrect readings from the sensor, it may trigger the E31 error.
Common Reasons This Error Appears
Blocked pressure hose
The small hose connected to the pressure sensor may be blocked with detergent residue or debris.
Faulty pressure sensor
The sensor responsible for measuring water levels may be malfunctioning.
Drainage issue
Water may not be draining correctly, causing the machine to detect an excessive water level.
Electrical connection problem
Loose or damaged wiring may prevent the pressure sensor from communicating with the control board.
Safe Checks You Can Try

Restart the washing machine
