Bosch Dishwasher Error Code E16 – Meaning and Possible Fixes
Bosch Dishwasher Error Code E16
If your Bosch dishwasher displays Error Code E16, it usually indicates that the appliance has detected an issue with the water inlet system. The dishwasher monitors how water enters the appliance during the start of the wash cycle.
If the dishwasher detects that too much water is entering, or that the inlet valve is not operating as expected, the appliance may stop the program and display the E16 error code.

What the E16 Error Means
The E16 error code generally indicates that the dishwasher has detected abnormal water intake during the filling stage. Bosch dishwashers use sensors to control how much water enters the appliance during each wash cycle.
If the system detects that the inlet valve is not regulating water properly, the dishwasher may interrupt the cycle and show the E16 error.
Common Reasons This Error Appears

If the valve controlling the water supply does not close properly, the dishwasher may detect excess water entering the appliance.

Temporary electronic fault
Occasionally a brief interruption in power or system glitch may cause the dishwasher to display an error.
