Dacor Dishwasher Error Code F-6

The F-6 code on a Dacor dishwasher signals a Controller/Floor Guard fault. This means the dishwasher's control system has detected a potential water leak in the base pan beneath the tub, or the floor guard sensor circuit has malfunctioned. The appliance stops operation to prevent water damage to your floor. Both the physical base pan and the electronic detection system should be inspected.

Yes, this code should be taken seriously because it can indicate an active water leak inside the appliance. Running the dishwasher while water is pooling in the base pan risks damage to your flooring, cabinetry, and the appliance itself. Do not continue operating the unit until the cause of the fault has been identified and resolved.

Repair costs vary depending on the cause. A door gasket replacement is typically a lower-cost repair, generally in the range of $50 to $150 including parts and labor. A floor guard sensor replacement is moderately priced. Replacing the main control board tends to be the most expensive option, with total repair costs potentially ranging from $200 to $500 or more. Getting a diagnostic quote from a certified technician before authorizing repairs is recommended.

Start by checking the base pan for standing water, which indicates an actual leak that must be located and repaired. If the base pan is dry, inspect the floor guard sensor and its wiring harness for damage or corrosion. If the sensor and wiring check out, the main control board may need to be tested or replaced. A qualified appliance technician can help pinpoint which component is responsible.

A reset may temporarily clear the code, but if an underlying problem exists such as a leak, a failed sensor, or a faulty control board, the F-6 fault will return when the dishwasher runs again. Resetting is useful for ruling out a one-time glitch, but it is not a permanent fix. The root cause must be addressed to prevent the error from recurring.
