Bosch Washer Error Code Er:11

Er:11 means the washer did not detect sufficient water entering the tub within 6 minutes of starting a fill cycle. The control board monitors incoming water flow and stops the cycle when this threshold is not met. The fault points to the water inlet valve, the wire harness connecting it to the control board, or the supply hoses. Diagnostic tests P8, P9, and P13 are used to pinpoint the cause.

It is not recommended to continue running the washer with an active Er:11 fault. The machine has already halted the cycle to prevent operating without adequate water. Forcing repeated attempts without resolving the underlying issue could cause additional wear on the control board or pump components over time.

A reset may temporarily clear the Er:11 code from the display, but the fault will return as soon as the washer attempts to fill again if the underlying problem has not been fixed. Resetting without addressing the cause, such as a failed inlet valve or blocked hose, will not resolve the issue. Always diagnose and correct the root cause before relying on a reset.

Some causes of Er:11 are easy to address without professional help. Start by confirming the water supply valves behind the washer are fully open, checking the inlet hoses for kinks, and cleaning the mesh screens at the hose connection points. If these checks do not resolve the fault, diagnosing and replacing the inlet valve or wire harness typically requires more technical knowledge and appropriate tools.

Repair costs depend on the specific cause. Cleaning hose screens or adjusting supply valves costs nothing. A replacement water inlet valve typically runs in the range of $30 to $100 for the part, with labor adding $80 to $150 if a technician is needed. Wire harness repairs can vary widely depending on the extent of the damage.
