Kenmore Washing Machine F4 Error Code
Pressure switch stuck during drain
What this error means
F4 appears when the pressure switch does not release during the drain portion of a cycle. The CCU still sees tub water when the drain pump should have emptied the drum.
How F4 is detected
When F4 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 F4 calls are resolved without parts: open the lower front access panel and twist out the pump clean-out filter. 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 F4 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
- Clogged drain pump filter slowing extraction
- Kinked drain hose behind the washer
- Pressure hose disconnected at the tub dome
- Failed drain pump not moving water
Step-by-step fixes
- 1Open the lower front access panel and twist out the pump clean-out filter
- 2Straighten the drain hose and confirm the standpipe drains freely
- 3Verify the pressure hose is firmly seated at the tub air dome
- 4Run Spin/Drain and watch whether water exits the emergency hose
When to call a technician
Standing water after Spin/Drain with a clear filter and hose points to a failed drain pump.
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 F4 from lint and food debris buildup.
- Record when F4 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 F4; Kenmore uses multiple revisions with different harness lengths and board firmware.
- Photograph wiring connector orientation before disconnecting any component while troubleshooting F4; reversed plugs on pumps and valves cause immediate repeat faults.
