Samsung Dishwasher Error Code 3E

The 3E code on a Samsung dishwasher indicates a circulation pump error. It is triggered when the pump motor speed falls below 2,400 RPM while the target is 2,600 RPM or more for three seconds, or when the inverter repeatedly reports motor errors. Sub-codes 3E1 through 3E4 identify more specific fault conditions within the circulation pump system. The most common cause is a physical blockage in the pump or circulation hose.

A reset may temporarily clear the 3E error code, but it will return if the underlying cause has not been resolved. To reset, you can power the dishwasher off at the circuit breaker for a few minutes and then restore power. If the pump is blocked or a component has failed, the fault will reappear as soon as the machine attempts to run a wash cycle.

Repair costs vary depending on the root cause. If the issue is a simple blockage, there may be no parts cost involved, though a service call fee typically ranges from around 75 to 150 dollars. Replacing a circulation pump motor generally costs between 150 and 350 dollars including parts and labor. An inverter board replacement can range from 200 to 400 dollars depending on parts availability and technician rates in your area.

Start by checking the circulation pump and hose for any foreign material such as broken glass, food debris, or small objects that may be blocking the impeller. Remove any obstruction found and run the dishwasher again to see if the error clears. If no blockage is present, the next steps involve inspecting the wiring connections to the pump motor and testing the pump motor and inverter board for electrical faults. Component replacement may be required if the motor or inverter has failed.

It is not recommended to continue running the dishwasher while the 3E error is active. If the circulation pump is not operating correctly, water will not be distributed through the spray arms properly, meaning dishes will not be cleaned or sanitized. Continuing to run the appliance with a failing pump motor could also place additional stress on the inverter board and worsen the damage.
