What Does Error Code 1C Mean on a Samsung Washing Machine?

Water level sensor error — pressure (level) sensor fault.

The 1C code (also shown as 1E or LC1) fires when the control loses a trustworthy water-level signal. Samsung uses a pressure sensor connected to the tub by a thin clear hose; air pressure rises as the tub fills. If that signal drifts out of range, or the hose is kinked, clogged, or loose, the reading becomes unreliable. The control halts fill and drain to avoid overflow or dry operation. Unlike PE, which flags a specific out-of-band value, 1C generally indicates a broken or disconnected sensing path.

Models affected: Samsung top-load and front-load washers with an analog pressure-based water-level sensor, spanning most recent model years
What owners report: Owners commonly report this appearing at the start of a cycle during fill, sometimes after moving the machine or after residue builds up in the sensing hose. A frequent quick win is simply straightening or clearing that small clear hose, which can clear the code without any parts.

What Causes Error Code 1C?

Here are the most common causes in order of frequency. Start with the most likely cause before moving to the next:

  1. 1
    Pressure sensor failure 45% of cases
  2. 2
    Pressure (sensing) hose kinked or clogged 35% of cases
  3. 3
    Hose connection loose at sensor or tub 15% of cases
  4. 4
    Control board sensor input fault 5% of cases

How to Fix Samsung Washing Machine Error Code 1C

🔧🔧 Moderate DIY Est. time: 30–60 min
⚡ Safety first: Unplug the appliance before opening any panels or touching internal components.
  1. 1

    Check the sensing hose

    Locate the small clear hose from the tub to the level sensor. Straighten kinks and clear any sludge.

  2. 2

    Blow test the sensor

    Disconnect the hose at the sensor and gently blow — you should hear a click as the diaphragm moves.

  3. 3

    Replace the level sensor

    If it doesn't click or tests out of range, replace it.

How to Reset Error Code 1C

Power off for 1 minute and restart. If 1C returns during fill, recheck the sensing hose for kinks before replacing the sensor.

Note: If the error returns after resetting, the underlying issue has not been resolved. Work through the fix steps above.

When to Call a Professional

If a new sensor and clear hose don't resolve 1C, the control board pressure input has failed.

Average professional repair cost for this issue: $150–$280

Frequently Asked Questions

Can I keep using my Samsung Washing Machine when error 1C appears? +
You often can for a cycle or two, but the sensor issue behind 1C will keep interrupting normal operation until it is fixed. Plan the repair rather than ignoring the code.
What most commonly causes 1C on a Samsung Washing Machine? +
Across reported Samsung washing machine repairs, the most frequent is pressure sensor failure (45% of cases), pressure (sensing) hose kinked or clogged (35%), then hose connection loose at sensor or tub (15%). Check them in that order before replacing any parts.
1C keeps coming back after a reset — what should I check next? +
A reset only clears the stored 1C fault; if it returns, the sensor problem is still present. Move on to the physical checks — check the sensing hose, then blow test the sensor — since the code will reappear until the root cause is resolved. This is a moderate job — a multimeter and some disassembly are usually involved.
How much does it cost to fix Samsung Washing Machine error 1C? +
A DIY repair typically runs $20–$60 in parts, versus $150–$280 for a professional service call, so handling it yourself saves around $130. Expect the work to take roughly 30–60 minutes.
Which Samsung Washing Machine models show error 1C? +
1C is documented on Samsung top-load and front-load washers with an analog pressure-based water-level sensor, spanning most recent model years. Other units sharing the same control platform can display it too, so the fixes here generally transfer across the series.
