Primary control board fault — board failed self-check

What Does Error Code F1 Mean on a Kenmore Washing Machine?
Primary control board fault — board failed self-check.
On Whirlpool-built Kenmore washers (110-prefix, including the Oasis/Cabrio top-load platform), F1 means the machine control board failed its own self-check or lost contact with a critical sensor input. The infamous 'Kenmore F1 error' on Oasis-era top-loaders was so common that the boards became a staple repair part.

Here are the most common causes in order of frequency. Start with the most likely cause before moving to the next:
- 1 Machine control board failure 60% of cases
- 2 Pressure sensor hose disconnected from the board 20% of cases
- 3 Connector backed out at the board 15% of cases
- 4 Power surge damage 5% of cases
How to Fix Kenmore Washing Machine Error Code F1

Power-cycle the washer
Unplug for 5 minutes and retry — a one-off F1 after a surge sometimes clears for good.

Reseat board connectors and the pressure hose
Unplug the washer, open the console/rear panel, and firmly reseat every connector — especially the small clear pressure-sensor hose, which slips off and produces F1.

Replace the control board
If F1 returns every cycle, replace the machine control. On Oasis/Cabrio-era models this is a well-documented 30-minute repair.

How to Reset Error Code F1
Unplug the washer for 5 minutes, plug back in, and start a Drain & Spin. Persistent F1 means the board needs attention — note whether it appears at the same point each cycle.
