KitchenAid Dishwasher F8 E4 Error Diverter Motor Position Sensor — Cheap Fix
F8 E4 on a KitchenAid (also Whirlpool / Maytag — same platform) dishwasher means the diverter motor or its position sensor failed. The diverter is the rotating disk in the sump that routes water between upper and lower wash arms; without it the dishwasher washes one rack at a time. Cheap, common, easy fix.

What we fix in Minneapolis
The Minneapolis repair mix
What the diverter does
Water enters the sump, the diverter disk rotates to direct it up either the upper-rack feed tube or the lower wash arm. The controller knows where it is via a Hall sensor under the disk. When the motor stalls or the sensor fails, you get F8 E4 and either the upper rack or lower rack stops cleaning.
Diverter motor replacement
Pull the bottom rack, remove the lower wash arm, unscrew the sump cover and pump cap, swap the diverter motor assembly (motor + sensor are integrated). 40 min job, $285–$425 OEM installed.
Don't replace the control board first
Common shop misdiagnosis is to swap the control board on F8 E4. The diverter motor is the right part 90%+ of the time. We always verify the diverter circuit at the connector before condemning anything more expensive.

FAQ
Minneapolis questions, answered
What does F8 E4 mean on a KitchenAid dishwasher?
Diverter motor or position sensor fault. Diverter routes water between upper and lower wash arms. $285–$425 OEM. The control board logs this code so technicians can skip generic troubleshooting. We carry the OEM service manuals on tablet for every major platform — no guess-and-replace.
Is F8 E4 the same on Whirlpool / Maytag?
Yes — KitchenAid, Whirlpool, and Maytag share the same dishwasher platform. F8 E4 is identical.
Will my dishwasher still work with F8 E4?
It'll run, but it washes only one rack at a time (whichever feed the diverter is stuck pointing at). Upper rack will look clean while lower stays dirty, or vice versa.
How much to fix F8 E4?
Most KitchenAid dishwasher repairs in the Twin Cities land $285–$425 all-in — parts, labor, and the $149 trip fee (which is credited toward the repair when you approve the work). Sealed-system or compressor work runs higher and we always quote that up front. Every job ships with a 1-year written parts-and-labor warranty.
