Bosch Dishwasher Error Code F68

F68 means the dishwasher's control board has detected that the circulation pump speed sensor is still reporting pump activity after the board issued a stop command. This is a protective fault that halts the cycle to prevent potential motor or electrical damage. The issue is most often related to wiring or connector problems at the speed sensor or control board, though the sensor or board itself may also be at fault.

It is not recommended to continue running the dishwasher while F68 is active. The error indicates a fault in the pump monitoring circuit, and operating the machine without resolving the underlying cause could lead to further electrical or motor damage. Diagnose and resolve the fault before resuming normal use.

A reset may temporarily clear the F68 code, but the error will return if the underlying fault in the speed sensor circuit has not been repaired. Resetting without diagnosing the cause does not fix the problem and could allow a wiring or component fault to worsen over time. A full inspection of the speed sensor connectors, wiring harness, and control board connections is necessary to resolve the error permanently.

The first diagnostic step is checking the connectors at the circulation pump speed sensor and the electronic control board, along with a continuity check of the wiring, which is within reach of a technically confident DIYer. If the fault traces to a failed speed sensor or damaged wiring harness, those repairs require basic electrical skills and comfort working inside the appliance. Control board replacement is more complex and may be better handled by a technician if you are not experienced with appliance electronics.

Repair costs vary depending on the root cause. If the fix involves reseating a connector or repairing a wiring harness, costs may be minimal, primarily covering labor if a technician is used. A replacement circulation pump speed sensor or pump assembly typically costs in the range of $40 to $150 in parts. A new electronic control board can range from $100 to $300 or more in parts alone, plus labor.
