What the Samsung 1C Code Means

1C typically indicates the washer’s control isn’t seeing the expected feedback from the water level (pressure) system. The washer uses a pressure sensor and a small air hose to “read” the water level. If the reading is off (or changes unexpectedly), the machine may stop to prevent overflow or damage.

Common Symptoms

• Washer stops mid-cycle or won’t start a fill properly
• Water level looks too low or too high for the cycle
• Drains unexpectedly or runs the pump more than normal
• Intermittent error that comes and goes
• Soap suds lingering (especially with HE detergent overuse)

Safety First

• If you see water on the floor, pause the washer and unplug it before inspecting.
• Turn off the hot and cold water supply valves if you suspect a leak.
• Do not remove panels or work around wiring unless you’re trained—water + electricity is a bad mix.

Quick Checks (Homeowner-Safe)

1) Look for small leaks (even slow drips matter)

• Check around the hose connections at the wall and the back of the washer.
• Look under the machine for moisture trails, mineral marks, or damp dust.
• Inspect the drain hose connection and the standpipe/laundry sink for splashing or overflow.

2) Make sure fill hoses aren’t kinked or crushed

• Pull the washer forward slightly and confirm both supply hoses have a smooth curve.
• Confirm the washer isn’t pinching the hoses against the wall.

3) Run a rinse & spin / empty cycle to rule out oversudsing

• If you used too much detergent (or non-HE detergent), suds can confuse water-level sensing.
• Run an empty rinse & spin. If needed, run a second rinse cycle.

4) Power reset

• Unplug the washer for 2 minutes, then plug back in and try a short cycle.
• If the code immediately returns, it’s more likely a sensor/hose/control issue than a one-off glitch.

Most Common Causes (and Likely Parts)

• Minor leak triggering water level changes or leak detection
  • Likely areas: hose connections, internal hoses/clamps, drain pump seal
• Pressure (water level) sensor / pressure switch issue
  • Sensor may not read correctly or may have an intermittent fault
• Pressure hose problem (pinched, loose, clogged)
  • A small air hose runs from the tub area to the sensor—if it’s compromised, readings go wrong
• Drain pump or drain path problems that cause unusual water-level behavior
  • Restriction, intermittent draining, or seal issues can create confusing level changes
• Main control board (less common, but possible)
  • If the sensor and hose test good, the control may be misreading the signal
