There is an issue with the power supply.

First step from the service manual

Wait until the power supply is stable. Ensure the power cord and wall outlet are in proper operating condition. Reset the appliance by either turning the knob to the reset position (12 o'clock position) or powering off the unit and back on.

What AL H0 means on a Electrolux dryer

The AL H0 error code on an Electrolux dryer indicates a power supply issue. This means the control board has detected an anomaly in the incoming electrical supply to the unit. The dryer's electronic control system continuously monitors the quality and stability of the power it receives, and when voltage fluctuations, drops, or surges fall outside acceptable operating parameters, the control triggers this alert to prevent potential damage to internal components.

The most common triggers for AL H0 are temporary voltage fluctuations from the utility grid, a loose or degraded power cord connection, or a wall outlet that is not delivering proper voltage. Since dryers require a stable power source to operate safely and accurately, even brief instability can cause this code to appear. The issue may be as simple as a momentary grid fluctuation that resolves on its own, or it could point to a persistent wiring or outlet problem that needs attention.

Diagnosing AL H0 starts with waiting to see if the power supply stabilizes on its own, then resetting the appliance. To reset, either turn the cycle selector knob to the 12 o'clock position or power the unit off and back on. If the code returns after resetting, the power cord and wall outlet should be inspected carefully for signs of damage, loose connections, or inadequate voltage delivery, as these are the most likely persistent causes.

Common causes of AL H0

  1. 01

    Temporary voltage fluctuation

    Wiring / connection

    A brief surge or dip in the utility grid's power supply can trigger AL H0. This often resolves on its own once the grid stabilizes, and a simple reset will clear the code.

  2. 02

    Loose or damaged power cord

    Part replacement

    A power cord that is not fully seated at the outlet or at the dryer terminal block can cause intermittent or insufficient voltage delivery. Inspect the cord along its full length for fraying, burn marks, or loose connections at both ends.

  3. 03

    Faulty or inadequate wall outlet

    Wiring / connection

    A wall outlet that is worn, wired incorrectly, or not supplying the correct voltage can trigger this error consistently. Testing the outlet with a multimeter or having an electrician inspect it will confirm whether the outlet is at fault.

  4. 04

    Tripped circuit breaker or partial breaker failure

    Wiring / connection

    A circuit breaker that has partially tripped can allow some voltage through while blocking the full supply the dryer needs. Check the breaker panel and fully reset the dryer's dedicated circuit breaker if it shows any sign of tripping.

  5. 05

    Faulty control board

    Part replacement

    If the power supply checks out as stable and correct but AL H0 continues to appear, the control board's power monitoring circuit may itself be malfunctioning and misreading the incoming supply. This is the least common cause and typically requires professional diagnosis.

Frequently asked questions about AL H0

What does AL H0 mean on a Electrolux dryer?
AL H0 on an Electrolux dryer means the appliance has detected a problem with its power supply. The control board monitors incoming voltage and triggers this code when it senses instability, a drop, or a surge outside normal operating parameters. It can be caused by grid fluctuations, a faulty outlet, or a damaged power cord. Resetting the dryer and inspecting the power connection are the recommended first steps.
Will resetting my Electrolux dryer clear the AL H0 error?
Resetting the dryer can clear AL H0 if the underlying power issue was temporary, such as a brief voltage fluctuation from the grid. To reset, turn the cycle selector knob to the 12 o'clock position or power the unit off and back on. If the error returns after resetting, the power cord, wall outlet, and circuit breaker should be inspected, as the root cause has not been resolved.
Is it safe to keep using my Electrolux dryer when AL H0 is displayed?
It is not recommended to continue operating the dryer while AL H0 is active, as the error indicates the appliance is not receiving a stable or proper power supply. Running a dryer under abnormal voltage conditions can stress internal components and potentially create a safety hazard. Address the power supply issue and confirm the error is cleared before resuming normal use.
How do I fix the AL H0 error on my Electrolux dryer?
Start by waiting a few minutes for any temporary grid fluctuation to pass, then reset the dryer by turning the knob to the 12 o'clock position or cycling the power off and on. Next, inspect the power cord for any visible damage and ensure it is firmly plugged into the outlet. If the code persists, test the wall outlet and check the circuit breaker, as a faulty outlet or tripped breaker is a common cause of this error.
How much does it cost to repair an Electrolux dryer showing AL H0?
The cost depends on what is causing the error. If the fix is simply resetting the unit or securing a loose power cord, there may be no cost at all. Replacing a damaged power cord typically costs between $20 and $60 for the part, while outlet repairs by an electrician can range from $75 to $200 depending on the work needed. If a faulty control board is the cause, parts and labor can range from $150 to $400 or more.
