Electrolux Washer Error Code EHC

The EHC code indicates a Line WD relay failure caused by an incongruence between the relay sensing circuit and the actual relay status. The main control board monitors whether a relay opens or closes as commanded, and when the sensed state does not match the expected state, this fault is triggered. The washer will stop operating until the underlying issue is resolved.

No, you should not continue running the washer while the EHC code is active. The fault indicates the control board cannot confirm the relay is behaving correctly, which means the machine may not be able to properly control water, motor, or drain functions. Running the washer in this condition could lead to water damage or further component failure.

A power reset may temporarily clear the EHC code, but if the underlying relay or board fault is still present, the code will return once the washer attempts to operate again. A reset is a reasonable first step to rule out a transient glitch, but a recurring EHC code after reset indicates a hardware fault that requires hands-on diagnosis and repair.

Some experienced DIYers can address this fault by inspecting the main control board for visible damage such as burned components or bad solder joints, and checking wiring connections to the relay circuit. However, confirming whether the relay or the board itself is the failed component requires electrical testing skills and appropriate tools. Replacing the main board is within reach of a skilled DIYer, but diagnosing the exact failed component correctly first is important to avoid unnecessary parts costs.

If the repair requires a new main control board, parts and labor costs typically range from $200 to $450 depending on the specific model and local labor rates. If only a relay component or a wiring repair is needed, costs can be lower, generally in the $75 to $200 range. Getting a diagnostic assessment from a technician before ordering parts is recommended.
