Maytag Washer Error Code E326

E326 indicates a short circuit has been detected on the RS485 communication connector, specifically on the power unit side. RS485 is the internal wiring that allows the washer's control boards to exchange data with each other. The washer stops operation when this fault is detected to prevent further electrical damage. The most common starting point for diagnosis is inspecting the communication cable and its connectors for damage or moisture.

A power reset may temporarily clear the error display, but E326 will return if the underlying short circuit condition in the RS485 communication cable or connector has not been corrected. Resetting the unit without addressing the fault is not a lasting solution and could allow the short to persist. The physical cause of the short must be identified and repaired before the error will stay cleared.

Repair costs vary depending on what component is at fault. If only the communication cable or connector needs replacement, parts and labor typically range from $75 to $200. If a control board or motor control module has failed, costs can range from $150 to $400 or more depending on the specific part and labor rates in your area. Getting a diagnostic assessment from a technician before committing to a repair is advisable.

A knowledgeable DIYer can inspect the RS485 communication cable and connectors for visible damage, pinching, or moisture, and cleaning corroded connectors may resolve the fault in some cases. However, if the wiring harness needs replacement or a control board has failed, those repairs are more involved and require comfort working with electronic components inside the washer. If you are not comfortable inspecting internal wiring, a qualified appliance technician is recommended.

You should not continue to operate the washer while the E326 fault is active. A short circuit on the communication wiring can interfere with the control system's ability to properly manage the motor, water valves, and other components, which could lead to unpredictable behavior or additional electrical damage. The washer should remain unplugged until the fault is diagnosed and repaired.
