Electrolux Washer Error Code EH3

EH3 means the washer has detected that the incoming supply voltage is too low for safe operation. The main control board monitors line voltage continuously and triggers this code when voltage drops below the nominal operating range. It can be caused by an external power supply problem or by a defective control board that is misreading the incoming voltage. The machine stops operation to prevent component damage.

It is not recommended to continue running the washer while EH3 is active. Operating under genuine low-voltage conditions can damage the motor, heating element, and control board over time. The error code is the machine's built-in protection telling you to resolve the power issue before resuming normal use.

Repair costs depend on the cause. If the issue is an external wiring or outlet problem, electrician service calls typically range from $75 to $200. A circuit breaker replacement generally falls between $50 and $150 including labor. If the main control board is defective, board replacement parts and labor combined can range from $150 to $400 or more depending on the specific model and local labor rates.

Start by measuring the voltage at the wall outlet using a multimeter to confirm whether the supply voltage is within the nominal range for your region. If voltage is low, check for loose wiring, a failing breaker, or contact your utility provider. If voltage is correct and the error persists, the main control board likely needs to be tested and replaced. Ensure the washer is plugged directly into a dedicated wall outlet and not an extension cord.

A reset may temporarily clear the EH3 code, but the error will return if the underlying cause has not been resolved. If the supply voltage is genuinely low or fluctuating, the board will detect it again and re-trigger the fault. Resetting is useful only for confirming whether the code was caused by a one-time voltage fluctuation rather than a persistent problem.
