Plain language
What this code means
Diverter disk missing: the control detected that the diverter disk in the sump is absent.
F9E3 is the shortest of the F9 entries. All it says is that the control found no diverter disk in the sump.
Stated and not stated
Given: the control sees the disk as missing.
Left out: the cause, how the disk went missing, and whether an owner could replace it.
Left out: a reset, or any first check.
Terms
The sump is the lowest part of the tub, where water gathers for the pump. A diverter sends wash water along one spray path or another. These are ordinary dishwasher terms, while the entry names just the disk and the sump.
Why so little
Both the service table and the job aid assume the machine is open in front of the reader. They note the detection and stop, with no owner-level steps.
Sensible handling
Since the source offers no steps, stop running the dishwasher and arrange service. Keep your hands out of the sump while power is connected. Tell the technician about anything out of the ordinary beforehand, such as a different sound or recent cleaning or repair.
Other F9 entries
F9E1: long drain, with a technician-side diverter position entry
F9E2: drain motor error, with a technician-side stuck diverter entry
