Error Code Explained

What Does the Samsung 1E Error Code Mean?

The 1E error code on a Samsung washer (also displayed as IE on some models) indicates a fault with the water level sensor (pressure switch). The control board uses the water level sensor to monitor how much water is in the drum at any point in the cycle. When the sensor signal is absent, unstable, or out of the expected range, 1E is displayed and the cycle is halted.

The water level sensor is a pressure-based device connected to the tub via a small rubber hose. It translates water pressure into an electrical signal the control board interprets as fill level. 1E is most often caused by a blocked or disconnected pressure hose rather than a failed sensor.

Root Causes

Common Causes of the Samsung 1E Error Code

1

Blocked or Kinked Pressure Hose

The small rubber hose connecting the tub to the pressure sensor is clogged with detergent residue or kinked, preventing accurate pressure readings.
2

Disconnected Pressure Hose

The hose has come off one of its two connection points — either at the tub fitting or at the sensor.
3

Failed Water Level Sensor

The pressure sensor itself has failed and is no longer producing a valid electrical signal.
4

Wiring Fault to Sensor

The wiring harness from the sensor to the control board has a break or loose connector.
5

Excess Suds Filling the Hose

Heavy suds buildup can enter the pressure hose and block the air column that the sensor relies on.

Step-by-Step Guide

How to Troubleshoot the 1E Error Code

⚠️

Safety First: Always disconnect the Washer from power before inspecting any internal components. Do not attempt electrical repairs. If in doubt, call a certified technician.

1

Power reset

Unplug the washer for 5 minutes and restart. A transient sensor glitch may clear.
2

Inspect and clear the pressure hose

Remove the top panel of the washer. Locate the small rubber hose running from the side of the outer tub up to the pressure sensor (a small cylindrical component on the control panel frame). Disconnect both ends and blow through it to confirm it is clear. Rinse with warm water if restricted.
3

Check hose connections

Confirm both ends of the pressure hose are fully seated on their fittings. A loose fit at either end will cause 1E.

When to Call a Samsung Technician

⚠ Stop DIY if any of these apply

If the hose is clear and correctly connected but 1E persists, the pressure sensor requires testing and likely replacement. If the sensor tests correctly, the control board is suspect.

FAQ

Frequently Asked Questions — Samsung 1E

Yes — 1E and IE represent the same water level sensor fault on different Samsung display types. The diagnosis and repair are identical.
No — the washer cannot safely fill or drain without a working water level sensor. It cannot determine when the tub is full and may overfill or fail to fill at all. Do not use the washer until 1E is resolved.
The pressure hose gradually accumulates detergent deposits, particularly with high-efficiency washers used with too much detergent. A hose that slowly narrows will eventually restrict enough to trigger 1E. Cleaning or replacing the hose resolves most sudden-onset 1E faults on older machines.
