Kenmore Washing Machine F15 Error Code
CCU internal memory check failed
What this error means
F15 is a secondary CCU memory fault on some Kenmore HE platforms—the control cannot pass its startup integrity check and may flash F15 before any cycle will start.
How F15 is detected
When F15 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 F15 calls are resolved without parts: unplug for ten minutes before restoring 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 F15 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
- Repeated power interruptions during a cycle
- CCU connector corrosion from steam at the door vent
- Manufacturing EEPROM defect on older CCU revisions
- Water drip onto the CCU from a leaking dispenser
Step-by-step fixes
- 1Unplug for ten minutes before restoring power
- 2Dry the CCU area if any moisture is visible on the mounting panel
- 3Reseat the large main harness and UI ribbon at the CCU
- 4Record the code and serial number before ordering a replacement board
When to call a technician
F15 displayed within seconds of power-on requires CCU replacement—do not attempt live board repair.
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 F15 from lint and food debris buildup.
- Record when F15 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 F15; Kenmore uses multiple revisions with different harness lengths and board firmware.
- Photograph wiring connector orientation before disconnecting any component while troubleshooting F15; reversed plugs on pumps and valves cause immediate repeat faults.
