Samsung Dishwasher Error Code bE3

The bE3 code means there is a key input error caused by a failure in the IC communications link between the Sub PBA and the touch button module. The two components communicate through connectors CN103 on the Display Control Module and CON100 on the TOUCH Module. When this communication breaks down, the dishwasher stops operating and displays the error. Moisture or condensation on these connectors is the most common cause.

No, you should not continue running the dishwasher while bE3 is active. The error indicates the control panel and touch input system are not communicating correctly, which means the dishwasher cannot respond reliably to commands. Operating it in this state could lead to unpredictable behavior or further damage to the control boards.

If the fix is simply drying out condensation and reseating the connectors, there may be no parts cost involved. If the TOUCH Module needs replacement, parts typically range from around $30 to $80 depending on the model. Replacing the Sub PBA is more involved and parts can range from $60 to $150 or more. Adding a technician's labor for diagnosis and repair generally brings the total to between $100 and $250.

In many cases, yes. Start by inspecting the Display Control Module connector CN103 and the TOUCH Module connector CON100 for any signs of condensation or moisture. Power the unit off, allow the boards to dry completely, and reconnect the connectors firmly before retesting. If the error returns after drying and reseating, further diagnosis or part replacement will likely be needed.

A reset may temporarily clear the code if condensation was the cause and the boards have had time to dry. However, if the underlying issue is a loose connector, corroded contacts, or a failed component, the bE3 error will return. A reset is a useful first step, but it is not a substitute for inspecting and addressing the root cause.
