Error Code: 4E Difficulty: Moderate
Problem: Water supply error – low flow rate or pressure switch fault
How to Fix 4E Error
- Clean inlet valve screens as per nF procedure.
- Verify water pressure minimum 20 PSI at source with gauge.
- Inspect pressure hose connection at tub top air dome – ensure not cracked or disconnected.
- Blow through pressure tube to clear moisture blockage (tube must be completely dry).
- Test pressure switch operation: disconnect tube, apply gentle suction while monitoring multimeter on switch terminals (should toggle at ~
- 5 PSI).
- Replace water level sensor DC96-01703C if switch fails continuity test or frequency output unstable.
- Check for air leaks in pressure system – submerge tube ends in water while running diagnostic fill cycle to spot bubbles indicating leaks.
Samsung Washer 4E Checks Before Replacing Parts
- Restart the washer and confirm the 4E message returns under the same condition instead of after a one-time interruption.
- Check the simple causes first: load balance, water supply, drain flow, door or lid closure, visible leaks, and power stability.
- Inspect accessible wiring connectors and moisture-prone areas before assuming the control board has failed.
- Use the complete Samsung washer model number from the door, lid, or rear tag before matching any pump, valve, sensor, suspension, lock, or board category.
- If the 4E code points to a specific system, test that system directly before ordering replacement parts.
