Samsung Error Code 1C
Water level sensor fault
Common Causes
- 1Pressure switch failure
- 2Hose disconnected
A malfunctioning water level sensor can cause overfilling. If the washer is filling non-stop, shut off the supply valves immediately to prevent overflow and potential water damage.
Step-by-Step Troubleshooting
- 1
Locate the pressure switch hose — a thin rubber or plastic tube running from the bottom of the outer tub up to the pressure switch (usually near the top of the machine at the back)
- 2
Check the hose for disconnections, cracks, or kinks. Blow gently through the hose — you should feel no blockage and hear a slight click from the pressure switch
- 3
If the hose is clogged, especially at the tub connection point, clean it with warm water. Sediment and soap residue are common blockages
- 4
Test the pressure switch by blowing into the hose while measuring continuity across the switch contacts — the switch should click and change state at a consistent pressure
- 5
If the switch does not click or is erratic, replace the pressure switch/frequency sensor assembly
Pro Diagnostic Tip
Samsung newer models use a frequency-based water level sensor instead of a mechanical pressure switch. These electronic sensors fail with an open circuit rather than sticking. Test with a multimeter for continuity at the sensor connector first.
