How to Fix Samsung Washer Error 1C
Problem: Water level sensor error or leak detected

How to Fix 1C Error
1. UNPLUG THE WASHER. This code indicates a water level sensor error or, less commonly, a leak.
2. First, check for any signs of a water leak under the machine. If a leak is found, the leak sensor has been tripped and the source of the leak must be found and repaired.
3. If there is no leak, the water level sensor (pressure switch) has likely failed. It is usually located near the top of the tub, accessible by removing the top panel of the washer. It has a thin air tube connected to it.
4. Disconnect the wire harness and the air tube from the old sensor. Check the tube for blockages or kinks. Remove the old sensor and install the new one.
5. Securely reattach the air tube and wire harness, then reassemble the washer.

How to Fix Samsung Washer Error 3C4
Problem: Motor error (alias for 3E4)

How to Fix 3C4 Error
1. UNPLUG THE WASHER. This complex error can be caused by a motor issue or excessive vibration from failed suspension fooling the motor control.
2. First, check for a mechanical issue. Try to move the tub up and down. If it bounces more than once or feels loose, the suspension rods are bad and must be replaced (see code 1Ub or Ub).
3. If the suspension feels firm, the issue is likely with the motor stator. This requires removing the rear panel and the motor rotor to access and replace the stator.
