Error codeF6E8
ApplianceDishwasher
Quick answer
F6E8 is an electrical entry for the softener regen valve, listed for 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.
Plain language
What this code means
Electrical problem in the water softener regen valve (softener models only): loose connection, open solenoid, open fuse or drive circuit.
Who sees this code
F6E8 is limited to dishwashers that have a built-in water softener. KitchenAid’s tech sheet describes it as an electrical problem in the softener’s regen valve.
Listed possibilities
Loose connection: wiring to the regen valve is not touching properly
Open solenoid: the valve’s operating coil is broken
Open fuse: a fuse in the circuit has blown open
Drive circuit: the part of the control that powers the valve
They appear as possibilities, with no ranking.
Regeneration in plain terms
Water softeners in general renew their softening material from time to time, and that renewal is called regeneration. The regen valve takes part in that step. For this dishwasher the source gives no description of the process, so how your machine carries it out is not covered here.
Without a softener
Since the entry is for softener models, compare the code on your display with care if you are unsure your machine has one. The same document includes other F6 codes, and a digit is easy to misread.
For the owner
No steps are given. Report the model number and the code F6E8.
