What the F8 error code actually means

Your Maytag dishwasher has detected a problem with the spray arm rotation system and stopped the cycle as a precaution. A sensor that monitors whether the spray arms are spinning correctly has either lost its signal or reported an unexpected result. This usually points to a loose wire connection, a faulty sensor, or less commonly a problem with the main control board.

Questions people ask about F8

What does F8 mean on a Maytag dishwasher?
The F8 code on a Maytag dishwasher indicates a wash arm fault. The control board has sensed a problem with the wash arm rotation system, typically through input from the Wash Process Sensor. This error can result from a wiring issue, a misconfigured sensor-to-arm assignment, a failed sensor, or in some cases a faulty control board.
Is it safe to keep using my Maytag dishwasher when F8 is showing?
Running the dishwasher while F8 is active is generally not recommended. If the wash arms are not rotating properly, dishes will not be cleaned effectively and water may not be distributed as intended. It is best to diagnose and resolve the fault before running additional cycles.
How much does it cost to repair a Maytag dishwasher with an F8 error?
Repair costs vary depending on the root cause. If the fix involves reseating a connector, there may be no parts cost at all. Replacing the Wash Process Sensor typically runs in the range of $30 to $80 for the part, while a control board replacement can cost $100 to $300 or more for parts alone. Adding professional labor will increase the total cost.
Can I fix the F8 error on my Maytag dishwasher myself?
Some causes of F8 are DIY-friendly, particularly checking and reseating wiring connectors between the Wash Process Sensor and the control board. Clearing debris from the spray arms is also straightforward. However, testing and replacing the Wash Process Sensor or control board typically requires more technical skill and comfort working with appliance electronics.
Will resetting my Maytag dishwasher clear the F8 error code?
A power reset may temporarily clear the F8 code, but if the underlying problem with the wash arm rotation system is not resolved, the error will return during the next cycle. Resetting is useful for confirming whether the fault is intermittent, but it is not a fix for a failed sensor, wiring issue, or control board problem.
