LG Dishwasher Error Code bE2

The bE2 code means the IC communication between the Sub PBA and the touch button panel has failed. This typically causes the display to go blank during a washing cycle. The fault is most often triggered by condensation or moisture reaching the electrical connectors on the control board. Inspecting those connectors is the recommended first diagnostic step.

A reset may temporarily clear the code, but if the underlying cause such as a loose connector or moisture-affected pin is not corrected, the bE2 error will return. Resetting is useful as a test step after you have inspected and corrected the connectors, but it is not a fix on its own.

Repair costs vary depending on the root cause. If the fix involves simply drying and reseating connectors, there may be little to no parts cost beyond a service call fee, which typically ranges from $75 to $150. Replacing a touch panel assembly or Sub PBA will add parts costs, generally pushing the total repair into the $150 to $400 range depending on the specific components needed and local labor rates.

In many cases, yes. If condensation on the PBA connectors is the cause, you can disconnect power, allow the unit to dry completely, and then inspect and reseat the connectors before restarting. However, if the problem is a corroded connector, a damaged wiring harness, or a failed board, repair becomes more involved and may require a technician.

Running the dishwasher with an active bE2 error is not recommended. Because the display goes dark during the cycle, you lose visibility into the machine's operating status, and the underlying communication fault could indicate a wiring or board issue that may worsen with continued use. It is best to diagnose and resolve the error before running additional cycles.
