Samsung Dishwasher Error Code bE2

The bE2 code signals a button error caused by condensation on the touch key connectors of the Main PBA. Moisture on these connectors generates false button input signals, causing the dishwasher to halt operation. The affected connectors vary by model: CN9 and CN10 on DMR77, CN10 on DMR57, and CN801 or CN803 on newer PBA variants. The issue is moisture-related and does not always indicate a failed part.

You should not attempt to run a wash cycle while the bE2 error is active. The false button signals could cause unpredictable operation. Power the unit off at the circuit breaker or unplug it while you investigate the connector area, and only resume use after the error is resolved and the board connectors are dry and undamaged.

If the fix is simply drying and reseating the connectors, the repair may cost nothing beyond your time. If a door gasket needs replacement, parts typically range from $15 to $50 depending on the model. A full Main PBA replacement is the most expensive outcome, with parts generally ranging from $80 to $200 or more, plus labor if a technician is needed.

In many cases, yes. If condensation is the only cause, powering off the dishwasher, allowing it to dry thoroughly, and inspecting the Main PBA connectors for moisture is often enough to resolve the error. Disconnecting and reseating the affected connectors after drying can also help. If the error returns repeatedly or you find corroded pins, further repair or parts replacement may be needed.

A reset may temporarily clear the code, but if condensation or a damaged connector is the underlying cause, the error will return when the dishwasher runs another cycle. A lasting fix requires drying or correcting the affected connectors. Resetting without addressing the root cause is not a long-term solution.
