What the 6-7 error code actually means
Your KitchenAid dishwasher is showing an error because it cannot read the sensor that tracks how much water is flowing through the machine. This usually means a wiring connection has come loose or the flow sensor itself has been damaged. A technician can run a specific test to determine whether the sensor or the control board needs to be replaced.

First diagnostic step
Disconnect power. Check connections at salt level sensor and at flow meter. Use meter to check for flow meter switch closed and salt level sensor. Disconnect flow meter and leave salt sensor connected. Apply magnet to side of salt tank near sensor. Run complete service diagnostics cycle; if sanitized LED turns on in interval 3, control is good and replace flow water assembly; if not, replace control.

Questions people ask about 6-7
What does 6-7 mean on a KitchenAid dishwasher?
Error code 6-7 on a KitchenAid dishwasher indicates a flow meter problem, meaning the control board is detecting either a disconnected or damaged flow meter. The flow meter monitors water movement through the wash system and operates alongside the salt level sensor. When the signal from the flow meter is absent or incorrect, the control board logs this fault and may halt normal operation.
Is it safe to use my KitchenAid dishwasher when error code 6-7 is displayed?
Running the dishwasher while the 6-7 error is active is not recommended because the control board cannot accurately monitor water flow, which may lead to wash performance issues or undetected water delivery problems. It is best to resolve the fault before continuing regular use. Disconnect power and inspect connections as a first step before attempting any wash cycles.
Will resetting my KitchenAid dishwasher clear the 6-7 error code?
A power reset may temporarily clear the error display, but the 6-7 code will return if the underlying issue with the flow meter or its wiring has not been resolved. Resetting is not a repair and should only be used as part of the diagnostic process. The fault requires physical inspection and targeted testing to identify and correct the root cause.
Can I fix a KitchenAid dishwasher 6-7 error myself?
A knowledgeable DIYer can perform the initial steps by disconnecting power and checking for loose connectors at both the flow meter and salt level sensor. The more advanced part of the diagnosis involves running a service diagnostics cycle and using a magnet on the salt tank to test sensor response, which requires familiarity with dishwasher diagnostic modes. If the wiring connections are secure and the fault remains, replacing the flow water assembly or control board is typically a job for an experienced technician.
How much does it cost to repair a KitchenAid dishwasher 6-7 error?
Repair costs vary depending on whether the issue is a loose wire, a failed flow water assembly, or a faulty control board. A simple wiring reconnection may only cost a service call fee, typically in the range of $75 to $150. Replacing the flow water assembly generally runs between $100 and $250 in parts and labor, while a control board replacement can range from $200 to $400 or more depending on the specific model and local labor rates.
