Samsung Washer 1E Error — Water Level Sensor Fix

What it means

Samsung washer 1E error means the pressure sensor (which measures water level in the tub) is reporting an unexpected reading — Samsung's 'Water level or leakage error'.
Either the sensor itself has drifted out of spec, or the small clear pressure hose between the tub and the sensor is blocked or detached.

Affected Models

  • Samsung Front Load Washer
  • Samsung Top Load Washer
  • Samsung AddWash Washer
  • Samsung EcoBubble Washer
  • Samsung QuickDrive Washer

Common Causes

  • Pressure sensor hose detached at one end
  • Pressure sensor hose pinched, kinked, or split
  • Pressure sensor (water level switch) faulty
  • Wiring loose between sensor and main control board
  • Trapped water in the pressure hose distorting readings

How to Fix It

  1. Power-cycle the washer.

    Unplug for 60 seconds, plug back in.
    One-off sensor read glitches sometimes clear on a clean reboot.

  2. Find and inspect the pressure hose.

    Remove the back panel.
    Look for a small clear plastic tube running from the bottom of the outer tub up to the pressure sensor (a small black cylinder).
    Confirm both ends are firmly connected and the tube isn't pinched, split, or full of trapped water.

  3. Blow out the pressure hose.

    Disconnect the hose at the sensor end.
    Gently blow into the hose to clear any trapped water or detergent residue.
    Reconnect.
    Detergent gunk in the hose throws the sensor reading out and triggers 1E.

  4. Replace the pressure sensor.

    If the hose is intact and clean but 1E persists, the sensor itself has failed.
    Replacement is a 30-minute job with the back open.
    Order the matching part for your model from Samsung parts.

When to Call a Professional

The pressure hose is owner-checkable; sensor replacement is technician-level.
The sensor itself is inexpensive (£10–£20) but accessing it usually needs the back panel off.

Frequently Asked Questions

What is the difference between Samsung 1E, LE, and LC errors?

All three are Samsung's 'Water level or leakage error' family — same root issue, different display formats on different model generations.
1E is most common on older washers; LE was used in the 2010s; LC is the newer alphanumeric form.
Causes and fixes are identical: pressure hose, sensor, then leak detection.
