F6E8 concerns the electrical side of the softener regen valve, on water softener models only.
Model compatibility: KitchenAid reuses codes across series and model years, so F6E8 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
What this code means
Water softener regen valve electrical problem on softener models only, from a loose connection, open solenoid, open fuse or drive circuit.
Only a dishwasher with a water softener built in should display F6E8. According to the KitchenAid tech sheet, the code is an electrical problem with the softener’s regen valve, for water softener models only.
At a glance
| Code | F6E8 |
|---|---|
| What it means | An electrical problem with the water softener regeneration valve, found only on softener models. |
| What you can check | There is no owner step for this code. First confirm on the display that it really reads F6E8, since it only applies to dishwashers with a built-in water softener. |
| When to call a technician | Arrange service, because the possible causes are a loose connection, an open coil, an open fuse or the drive circuit, all of which are electrical. Give the technician the code and model. |
Table of listed items
| Item | What it means |
|---|---|
| Loose connection | Contact is lost in the wiring that reaches the regen valve |
| Open solenoid | There is a break in the coil that works the valve |
| Open fuse | A fuse in the circuit is open |
| Drive circuit | The section of the control supplying power to the valve |
The sheet offers these as possibilities and does not order them.
The word “regen”
Softeners in general are regenerated now and then, meaning the softening material is cleaned so it keeps working; the regen valve belongs to that step. The source does not lay out the process for this dishwasher, so specifics for your model are absent.
Not sure there is a softener?
Look again at the display. The document has other F6 entries, so swapping a digit is easy to do.
Owner steps
None appear. Pass the model number and the code F6E8 to the technician.
