GE Dishwasher Error Code F151

The F151 code on a GE dishwasher signals a continuous flow fault, meaning the water level inside the tub has reached flood stage multiple times during one cycle and the machine has had to drain repeatedly as a safety response. This indicates a problem with water fill control, the water level sensing system, or the drain system. It is not a one-time overfill event but a recurring pattern that the control board has detected as abnormal. The dishwasher will typically halt normal operation until the fault is resolved.

It is not recommended to continue running the dishwasher while the F151 fault is active. The fault indicates the water level is reaching flood stage multiple times, which means there is a real risk of water escaping the tub and causing floor or cabinet water damage. Stop using the appliance and diagnose the cause before running another cycle.

Repair costs depend on the root cause. Clearing a clogged drain or freeing a stuck float switch involves little to no parts cost and minimal labor. Replacing a water inlet valve typically costs between $25 and $80 for the part, while a water level pressure sensor generally ranges from $20 to $60. Adding professional labor, total repair costs can range from $100 to $250 or more depending on the technician's rates and the specific component involved.

Some causes of F151 are DIY-friendly, such as clearing debris from a stuck float switch or cleaning a clogged drain filter and hose. However, replacing the water inlet valve or water level pressure sensor requires comfort with disconnecting water supply lines and electrical connectors. If you are not experienced with appliance repair, having a technician diagnose the root cause first is advisable to avoid replacing the wrong component.

A reset may temporarily clear the F151 code from the display, but if the underlying cause such as a faulty inlet valve or malfunctioning water level sensor is still present, the fault will return during the next wash cycle. Resetting is useful for confirming whether the fault is intermittent, but it does not fix the mechanical or electrical problem causing the repeated flood conditions.
