Samsung Washer Error Code C1

The C1 code indicates a water level sensor error. The washer uses a pressure sensor connected to the tub by a small hose to monitor how much water is inside the drum. C1 appears when that sensor cannot provide accurate readings, which can be caused by a damaged, clogged, kinked, or disconnected hose, a loose electrical terminal, faulty sensor soldering, or a defective main control board.

No, you should not continue running the washer with C1 active. The water level sensor is a critical safety component that prevents the machine from overfilling or running without adequate water. Operating the washer in this condition could cause flooding or damage to internal components such as the motor and heating element.

Repair costs vary depending on the root cause. If the issue is only a kinked or disconnected hose, there may be no parts cost at all, just time for inspection. Replacing a damaged sensor hose is generally inexpensive, typically in the range of $10 to $30 for the part. If the water level sensor itself needs replacement, parts and labor combined can range from $75 to $200. A main PBA replacement is the most costly scenario, often ranging from $150 to $400 or more depending on the model and labor rates.

Many C1 errors can be resolved without professional help. Start by unplugging the washer and locating the water level sensor hose, then check it for kinks, clogs, holes, and loose connections at both ends. If the hose is simply kinked or disconnected, reconnecting or straightening it may clear the fault. If the hose is damaged or the error persists after hose inspection, the sensor or control board may need to be replaced, which typically requires a technician.

A reset may temporarily clear the display, but the C1 code will return if the underlying problem is not corrected. To reset, unplug the washer for a few minutes and then restore power. If the code reappears immediately or on the next wash cycle, the physical or electrical fault causing the sensor error must be diagnosed and repaired before the machine will operate reliably.
