Samsung Washer Error Code Tap Cold LED Flash

The Tap Cold LED Flash error indicates a water level sensor fault. The washer uses a pressure sensor and a connected hose to measure water inside the drum, and this error means that signal is missing or incorrect. Causes include a damaged, clogged, or disconnected sensor hose, a loose sensor terminal, faulty soldering inside the sensor, or a main control board fault.

You should not continue using the washer while this error is active. The water level sensor controls how much water enters the drum, and if it is not functioning correctly, the washer could overfill or operate improperly. Address the fault before running another cycle.

A reset may temporarily clear the error code, but if the underlying fault is still present, the error will return once the washer attempts to sense the water level again. The root cause, whether it is a hose issue, a connector problem, or a failed sensor, must be corrected for the error to stay cleared.

Many cases of this error can be resolved without professional help. Start by inspecting the sensor hose for kinks, folds, cracks, and secure connections at both ends, then check that the sensor terminal connector is fully seated. If the hose is clogged, clearing it may resolve the fault. If the sensor or main PBA has failed, those components will need to be replaced, which is a more involved repair.

Cost depends on the failed component. Clearing a clogged hose or reseating a loose connector costs nothing beyond your time. A replacement water level sensor typically runs in the range of $15 to $60 for the part. A main PBA replacement is the most expensive outcome, with parts generally ranging from $100 to $300 or more depending on the model, plus labor if a technician is hired.
