Risk level

Medium

Proceed carefully and stop if the check is unclear.

Urgency

High

Quick answer

1C or 1E means the washer cannot use the expected water-level signal. Stop if the visible level does not match the programme or water keeps entering.

Safety first

Stop and check this first

  • Stop immediately for overfilling, continuous draining or any leak near electricity. Never bypass a level sensor or keep resetting the washer.

Safe checks you can perform

  • Compare the visible level with the cycle
  • Close water and isolate power if abnormal
  • Record symptoms without opening panels

Leave these tasks to a qualified professional

  • Do not attempt this professional task: Test the full water-level sensing path

What a technician must be able to justify

Technician visit

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.

These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.

  1. Test the full water-level sensing path

    What they doA technician should check the pressure chamber, hose, sensor, harness, moisture evidence and control interpretation for the model.

Before accepting a part or repair

Nothing has been shown yet. Do not accept a part swap based on the code alone.

Follow these steps

Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.

  1. Compare the visible level with the cycle

    No special tools

    Stop the programme if the drum appears overfilled, empty when it should contain water or continues filling after the cycle pauses.

    Stop immediately for overfilling, continuous draining or any leak near electricity. Never bypass a level sensor or keep resetting the washer.

  2. Close water and isolate power if abnormal

    No special tools

    If the level rises or a leak is visible, close the accessible supply valves and disconnect power without touching wet equipment.

    Stop immediately for overfilling, continuous draining or any leak near electricity. Never bypass a level sensor or keep resetting the washer.

  3. Record symptoms without opening panels

    No special tools

    Photograph the code and note filling or draining behaviour; do not blow into pressure hoses or run undocumented calibration steps.

    Stop immediately for overfilling, continuous draining or any leak near electricity. Never bypass a level sensor or keep resetting the washer.

What it means

Samsung regional guides associate 1C and 1E with the pressure or water-level sensor. US guidance can group related variants with leakage detection, so the complete pressure and moisture path requires model-specific diagnosis.

Warnings and stop conditions

  • Mediumsource verified

    Stop immediately for overfilling, continuous draining or any leak near electricity. Never bypass a level sensor or keep resetting the washer.

Symptoms and causes

Probable causes · in order

  • The pressure signal is outside its valid rangeConfirmed

    The control cannot translate the reported pressure into a reliable water level for the current stage.

    Evidence: Samsung US washing machine information and error codes

  • The sensing path or its connection is disturbedPossible

    A restricted pressure chamber, hose leak, sensor connection or control input can produce the same family of codes.
