Samsung Washer Error Code 4C

The 4C code on a Samsung washer indicates a water supply error. The machine is not receiving water as expected, which can be caused by kinked supply hoses, debris blocking the inlet valve, a disconnected valve terminal, a damaged pressure hose, or incorrectly routed PCB connectors. The washer stops the cycle to protect the motor and drum from running dry.

No, you should not continue running the washer while the 4C error is active. The code means the drum is not filling correctly, and running a wash cycle without adequate water can stress the motor and damage other components. Address the cause of the error before resuming use.

If the fix is simply straightening a kinked hose or cleaning the inlet valve screens, there is no parts cost and the repair is a DIY task. If the water supply valve itself has failed and needs replacement, parts typically range from around $25 to $75 depending on the model, with professional labor adding $80 to $150 or more depending on your region. A damaged pressure hose is generally an inexpensive part, but diagnosis time may add to the total service cost.

Start by checking that the water supply taps behind the machine are fully open and that the inlet hoses are not kinked or bent. Next, turn off the water and inspect the mesh filter screens inside the valve inlet ports for debris, rinsing them clean if needed. If the hoses and screens are clear, check that the wiring terminal at the water supply valve is firmly connected and that the pressure hose is intact and properly seated at both ends.

A reset, done by unplugging the washer for a few minutes and restarting, may temporarily clear the code, but it will return if the underlying issue is not resolved. The 4C error is triggered by a detected condition in the water supply system, so the root cause must be corrected for the fault to stay cleared.
