Samsung Dishwasher Error Code IE

IE stands for inverter communication error. It means the main control board sent a signal to the inverter motor control board and did not receive a response within 3 seconds. The dishwasher attempts to recover by cycling the inverter relay off and waiting 2 minutes, repeating this 3 times before displaying the code. The fault most commonly originates in the wiring or connectors between the two boards.

No, the dishwasher will not operate normally with the IE error active. The machine has already attempted a recovery cycle and stopped. Continuing to run cycles while this error is present is not advisable, as the wash motor may not be functioning correctly. The dishwasher should be diagnosed and repaired before returning to regular use.

Repair costs vary depending on whether the fix is a simple reseating of connectors or requires replacing a board. If only the wiring harness connection needs attention, the cost may be limited to a service call fee, typically in the range of $75 to $150. Replacing an Inverter PBA or Main PBA will add parts costs, and total repair estimates for board replacements generally range from $150 to $400 or more depending on parts pricing and labor rates in your area.

The first step is to check the wiring harness connections between the Main PBA and Inverter PBA, which requires accessing the control area of the dishwasher. If the connectors are secure and the error persists, testing the harness for continuity and inspecting for corrosion are the next steps. Replacing the inverter PBA or Main PBA requires comfort working with electronic components and disconnecting power safely. Technicians with experience in appliance electronics can often handle this repair, but less experienced users may want professional assistance.

A power reset may temporarily clear the IE code from the display, but the error will return if the underlying communication fault is still present. The dishwasher's control logic will run through its 3-attempt recovery sequence again and redisplay the code. A reset is useful for confirming whether the fault is intermittent, but it does not substitute for diagnosing the wiring and boards.
