Kenmore Washing Machine F7 Error Code
Motor control processor fault
What this error means
F7 means the Motor Control Unit detected an internal processor fault. The drive system stops and the drum will not agitate or spin until the MCU resets or is replaced.
How F7 is detected
When F7 appears on a Kenmore washing machine, the control board has confirmed that water did not leave the machine within the programmed drain window. On Kenmore Elite 41382 31102, Kenmore Elite 41952 99111, and similar variants, the drain pump runs for a fixed interval—often three to seven minutes on washers and dishwashers—while a pressure switch or turbidity sensor verifies the tub or sump is empty. If water remains, the cycle stops to prevent spin with a full tub or overflow on the next fill.
Most F7 calls are resolved without parts: unplug five minutes and restore power. Restricted drain paths mimic pump failure because the impeller spins against a blocked hose or filter. Document whether the pump hums audibly during the drain step; a humming pump with no water movement points to a clogged filter or kinked hose, while silence may indicate a failed pump motor or loose wiring at the harness.
After clearing blockages, run a short cycle and listen at the drain hose for steady water flow. If F7 returns on the next load with a clean filter and straight hose, measure resistance at the pump motor connector per the service manual for your model before ordering a replacement pump assembly.
Common causes
- Power surge damaging the MCU processor
- Loose MS2 harness between CCU and MCU at the top rear
- Moisture on the MCU from a prior inlet leak
- Failed MCU EEPROM or drive processor
Step-by-step fixes
- 1Unplug five minutes and restore power
- 2Remove the top cover and reseat the MS2 connector at the CCU
- 3Inspect the MCU mounted on the left cabinet wall for burn marks
- 4Run a short spin cycle as a functional test after harness reseat
When to call a technician
Persistent F7 after reseating MS2 and M13 connectors requires a new Motor Control Unit matched to your model suffix.
Affected models
- Kenmore Elite 41382 31102
- Kenmore Elite 41952 99111
- Kenmore 22202 90002
Prevention & maintenance
- Clean drain filters and hose terminations monthly on high-use washing machines to prevent F7 from lint and food debris buildup.
- Record when F7 appears in the cycle and whether it clears after a 60-second power reset on your Kenmore washing machine—that detail speeds diagnosis if you call service.
- Keep the model and serial number from the rating plate when ordering parts for F7; Kenmore uses multiple revisions with different harness lengths and board firmware.
- Photograph wiring connector orientation before disconnecting any component while troubleshooting F7; reversed plugs on pumps and valves cause immediate repeat faults.
