A code names the subsystem; the symptom is what sent you to look at the display in the first place. That page says what it usually turns out to be, cheapest cause first.

A full cycle later and the load comes out dirty Dishwasher not cleaning
On South Florida water a good share of these are chemistry and temperature rather than a failed component. The useful distinction is what is left on the dishes: grit is one story, film is a completely different one, and they lead to different places.
- Grit and film are two different problems
- Water temperature is measured, not assumed
- Hard water is a real factor here

What else belongs to the dishwashers
On this make a code belongs to the appliance rather than to a product line. These are the other conditions this machine can display, and the models that can show this one — a display often has more than one thing to say, and the model number decides what any of it costs to put right.

About Whirlpool-built Kenmore dishwasher error code F4 E2
Whose code this actually is
Kenmore did not write F4 E2, because Kenmore has never built an appliance. This one is Whirlpool's, and it appears on the dishwasher that Whirlpool built and Sears sold under the Kenmore badge. Whirlpool, Frigidaire and Bosch all built dishwashers for this badge, and their numbering overlaps enough to be convincing while meaning entirely different things.
What it means
The heating system. Whirlpool labels the pair as a heating error.
Which Kenmore models can raise it
The Kenmore dishwasher whose model number begins 665 — the three digits before the period on the rating plate. Those digits are Whirlpool's, which is why Whirlpool's table is the one that applies to F4 E2 and no other manufacturer's does.
The other ways it may be written
The same condition is published under more than one label, because it has been carried across generations of the appliance and because a segment display draws some characters oddly: F4 E3. They are the same finding and they lead to the same place.
What happens next
- Dishes that come out wet with this showing is the signature.
- On this water a heater scales, and a scaled heater fails early.
Where this usually goes
The job this most often becomes is dishwasher wash performance service, and that page carries a starting figure and the reasons that move it. A Kenmore dishwasher on this water scales its heater and its spray arms faster than the manual assumes, so codes about temperature and wash performance are read here with the supply in mind first. Photograph the display before you cut the power: a reset clears F4 E2, and on a Kenmore the characters plus three digits off the plate are most of the diagnosis.
Where this meaning came from
Whirlpool's own documentation: Dishwasher error codes and flashing lights — Whirlpool Product Help. Kenmore publishes none of its own, which is why every entry on this site names the manufacturer's document instead.
