Error Code Explained

What Does the Samsung 1E Error Code Mean?

The 1E error code on a Samsung dishwasher (also shown as IE on some display types) indicates a water level sensor (pressure switch) fault. The water level sensor monitors how much water fills the tub during the wash cycle. When the sensor signal is absent, out of range, or indicates an abnormal water level, 1E is displayed and the cycle halts.

On Samsung dishwashers, 1E is most commonly caused by a failed pressure sensor or a blocked pressure hose leading to it. In some cases, a failed water inlet valve that allows too little water in can also produce a 1E reading.

Root Causes

Common Causes of the Samsung 1E Error Code

1

Failed Water Level Sensor

The pressure-based water level sensor has failed electrically and is no longer producing a valid signal.
2

Blocked Pressure Hose

The small hose connecting the tub sump to the pressure sensor is clogged with grease or debris, preventing accurate pressure transmission.
3

Insufficient Water Fill

The water inlet valve is restricted or failing, allowing too little water into the tub — not enough to register on the sensor.
4

Wiring Fault to Sensor

A loose or corroded connector on the sensor wiring harness.

Step-by-Step Guide

How to Troubleshoot the 1E Error Code

⚠️

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

1

Power reset

Turn off the dishwasher at the circuit breaker for 5 minutes. A transient sensor glitch may clear on restart.
2

Check water supply

Confirm the supply valve under the sink is fully open and the inlet hose is not kinked. Insufficient supply pressure can prevent adequate fill and trigger 1E.
3

Inspect the pressure hose

Locate the small rubber hose from the sump to the pressure sensor (typically near the base of the tub). Disconnect and blow through it to confirm it is clear.

When to Call a Samsung Technician

⚠ Stop DIY if any of these apply

If the supply is adequate and 1E persists after a reset and hose inspection, the water level sensor requires replacement.

FAQ

Frequently Asked Questions — Samsung 1E

Yes — 1E and IE are the same fault on different display types. The number 1 and the letter I are visually similar and both represent the water level sensor fault.
Yes — if the sensor itself has failed, it may not correctly detect water even when the tub fills normally. The dishwasher cannot verify the fill level and halts as a precaution.
