KitchenAid Dishwasher Error Code F6E7

F6E7 indicates that the control board has detected a disconnected or damaged flowmeter in the water softening system. The flowmeter monitors water flow through the salt regeneration circuit and communicates that data back to the control board. When the signal is absent or the circuit is open, the dishwasher logs this fault code. The salt level sensor wiring is also checked as part of the diagnosis since both components share the same circuit path.

The F6E7 fault is related to the water softening system rather than the primary wash function, so the dishwasher may still operate in some capacity. However, without a functioning flowmeter, the salt regeneration cycle cannot be properly managed, which could affect wash performance over time, particularly in hard water areas. It is best to diagnose and resolve the fault before continued heavy use.

If the fix is limited to reseating a connector or cleaning corroded terminals, the repair may cost nothing beyond your time. A replacement flowmeter part typically runs in the range of $30 to $80 depending on the specific model. If a service technician is needed for diagnosis and repair, total costs including labor could range from $100 to $250 or more depending on what components require replacement.

Many cases of F6E7 are caused by a loose or corroded wiring connector, which a confident DIYer can address by disconnecting power, locating the flowmeter and salt level sensor connections, and reseating or cleaning the terminals. Testing the flowmeter switch with a multimeter is also within reach for someone comfortable with basic electrical diagnostics. If the flowmeter itself has failed or the control board is at fault, replacement parts and more advanced diagnosis may require a qualified technician.

A power reset may temporarily clear the F6E7 code, but it will return if the underlying problem with the flowmeter or its wiring has not been corrected. Simply cycling the power does not repair a failed switch, broken wire, or corroded connector. The fault needs to be diagnosed and repaired at the component level for the code to stay cleared.
