KitchenAid Dishwasher Error Code F8E6

F8E6 means the dishwasher's control board has detected that the flow meter is either disconnected or not functioning. The flow meter measures water entering the machine during a fill cycle. This code has a special priority behavior: it blocks all other error codes from appearing, so it must be resolved before any additional faults can be identified and diagnosed.

A reset may temporarily clear the code from the display, but F8E6 will return as soon as the dishwasher runs again if the underlying issue has not been resolved. Because this code also suppresses other error codes, it is important to actually diagnose and fix the flow meter problem rather than relying on a reset.

If the fix is simply reseating a loose connector or clearing a debris blockage, there may be no parts cost involved, though a service call typically runs between $75 and $150. If the flow meter itself needs replacement, parts plus labor generally range from $150 to $300 depending on your location and the specific model. Damaged wiring harnesses can fall anywhere in that same range depending on the extent of the repair.

Some causes of F8E6 are straightforward DIY repairs. After unplugging the dishwasher, check whether the flow meter connector is loose and whether any wires appear pinched or damaged. Also inspect the water inlet for debris blocking the flow meter wheel. If the meter itself is confirmed failed or wiring is severely damaged, a technician with the right parts can complete the repair.

It is not advisable to continue running the dishwasher while F8E6 is active. Without a functioning flow meter, the control board cannot accurately monitor water intake, which could lead to improper fill cycles or other operational faults. Additionally, any other faults present in the appliance will remain hidden until F8E6 is cleared.
