Maytag Dishwasher Error Code F6-E7

F6-E7 on a Maytag dishwasher means the control board has detected that the flowmeter is either disconnected or damaged. The flowmeter monitors water flow during wash cycles and works alongside the salt level sensor on models with built-in water softeners. The dishwasher will not operate normally until the issue is resolved.

A reset may temporarily clear the code from the display, but it will return as soon as the dishwasher attempts to run a cycle and cannot read the flowmeter signal. The underlying cause, whether a loose connection or a failed component, must be corrected for the code to stay cleared.

If the fix is simply reseating a loose connector, the repair can cost nothing beyond your time. If the flowmeter itself has failed and needs replacement, parts typically range from roughly 30 to 80 dollars depending on the model, with professional labor adding anywhere from 100 to 200 dollars or more. A damaged wiring harness repair can vary widely depending on the extent of the damage.

Start by disconnecting power to the dishwasher, then check all wiring connections at both the flowmeter and the salt level sensor for looseness or corrosion. Use a multimeter to test whether the flowmeter switch closes as it should. If the switch does not close, the flowmeter needs to be replaced. If connections and the switch both check out, inspect the wiring harness for damage between the flowmeter and the control board.

Running the dishwasher with an active F6-E7 code is not recommended. Without a functioning flowmeter, the control board cannot properly monitor water flow, which can lead to incomplete cycles or improper water softener regeneration on equipped models. It is best to diagnose and correct the fault before resuming normal use.
