Samsung Washer Error Code Hot&Tap Cold LED Flash

This LED flash pattern signals that the washer's control system has detected a fault related to the MEMS PBA, which is a dedicated circuit board governing specific functions including the silver nano feature. The error can point to a faulty wire connection between the MEMS PBA and the main control board, a problem with the MEMS PBA itself, or a data code error on that board. Diagnosis involves inspecting wiring harnesses and potentially replacing the MEMS PBA.

It is not recommended to continue running the washer while this error is active. A fault in the MEMS PBA or its wiring can affect the washer's ability to operate certain functions correctly, and running cycles in this state could potentially worsen the underlying issue. The washer should be inspected and the fault resolved before returning it to regular use.

If the fix is simply reseating a loose wire connector, there may be no parts cost, though a service call typically runs in the range of $75 to $150 depending on the technician and location. If the MEMS PBA requires replacement, parts and labor combined can range from $150 to $350 or more depending on the specific model and part availability. Getting a diagnostic estimate before authorizing repairs is a good way to determine whether repair or replacement makes more financial sense.

A homeowner comfortable with basic appliance work can start by unplugging the washer and carefully inspecting the wire harness connections at the MEMS PBA and main PBA for anything loose, corroded, or disconnected. Reseating connectors may resolve the fault if a wiring issue is the root cause. If the board itself has failed, replacing the MEMS PBA is a more involved repair that typically requires identifying the correct board for the model and careful reassembly.

A power reset by unplugging the washer for a few minutes may temporarily clear the error display, but it will not resolve the underlying hardware problem causing the fault. If the MEMS PBA has a wiring issue or a component failure, the error will return once the washer is powered on and the system performs its self-check. A proper diagnosis and repair is needed to permanently clear the code.
