Whirlpool Dishwasher Error Code F6E7

F6E7 means the control board has detected that the flow meter is disconnected or damaged. The flow meter measures water entering the dishwasher and signals the board by opening and closing an internal contact. When that signal is missing, the board triggers F6E7 and may stop the wash cycle to prevent an overfill condition.

Running the dishwasher with an active F6E7 code is not recommended. Without a functioning flow meter, the control board cannot accurately track how much water has entered the tub, which increases the risk of overfilling. It is best to leave the appliance off until the flow meter connection or the meter itself has been inspected and repaired.

A power reset may temporarily clear the F6E7 code from the display, but the fault will return as soon as the dishwasher attempts a fill cycle if the underlying problem has not been fixed. The code is triggered by an active electrical fault, not a stored memory glitch, so a reset alone is not a repair. The flow meter connection or the meter itself must be addressed for the error to stay cleared.

Start by disconnecting power to the dishwasher, then locate the flow meter and check that its wiring harness connector is fully seated and free of corrosion. Also inspect the salt level sensor connections, as both components share a related circuit. If connections look good, use a multimeter to test whether the flow meter produces a contact closure when water passes through it. A meter that does not respond will need to be replaced.

If the problem is simply a disconnected or dirty connector, the repair may cost nothing beyond your time. A replacement flow meter part typically falls in the range of $20 to $60, depending on your specific model. Adding professional labor brings the total repair cost to roughly $100 to $200 in most cases.
