F9E3 is a short service entry: the diverter disk in the sump has gone missing.
Model compatibility: KitchenAid reuses codes across series and model years, so F9E3 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
Diverter disk missing: the control has detected that the disk in the sump is not present.
The F9 group’s shortest explanation belongs to F9E3. The entry says the control has detected a missing diverter disk in the sump, and nothing further.
At a glance
| Code | F9E3 |
|---|---|
| What it means | Diverter disk missing: the control has detected that the disk in the sump is not present. |
| What you can check | There is no owner fix for this code, so stop using the dishwasher. Leave the sump alone while the machine has power, and note any odd sounds or recent repairs. |
| When to call a technician | Book a service visit, since the missing disk is a job for someone who can open the cabinet. Tell the technician about anything unusual you noticed. |
The parts involved
The sump, at the bottom of the tub, is where water pools and the pump takes it up. A diverter switches the wash water from one spray path to another. Those definitions are general ones; KitchenAid’s entry only mentions the disk and the sump.
What the entry covers
- It reports that the control sees the disk as absent.
- It omits why or how it went missing, and whether an owner may replace it.
- It omits resets and anything to check beforehand.
Only the detection is recorded because the service table and job aid address someone who has already opened the cabinet.
What to do
No steps come from the source. The reasonable course is to stop using the machine and book service. Leave the sump alone while the dishwasher has power. Mention to the technician any unusual change you noticed, such as how it sounded, or a recent repair or cleaning.
The rest of the F9 family

|---|---|
| F9E1 | Long drain; the technician tables add a diverter that cannot locate its position |
| F9E2 | Drain motor error; the technician tables add diverter stuck on |
