What the E73 error code actually means

Your Electrolux induction cooktop is showing E73 because an internal circuit board that controls power to three of your cooking zones is not producing the correct voltage. This could be caused by a loose wire connection or a faulty electronic board inside the cooktop. The cooktop has shut down this module as a safety measure, and a technician will need to inspect or replace the affected components.

Questions people ask about E73

What does E73 mean on a Electrolux cooktop?
E73 indicates an improper voltage output from the filter circuit board inside the 3-cook-zone induction module. This fault is equivalent to E33 and points to a problem within the same module and board assembly. The cooktop disables the affected zones to prevent further damage when this condition is detected.
Will resetting the cooktop clear the E73 error?
A power reset may temporarily clear the E73 code, but the error will return if the underlying electrical fault on the filter circuit board or its connections has not been resolved. The cooktop should not be used on the affected zones until the root cause is diagnosed and corrected.
How much does it cost to repair an E73 error on an Electrolux cooktop?
Repair costs depend on which component requires replacement. A service call alone typically runs between $80 and $150. If the filter circuit board or a generator circuit board needs to be replaced, parts and labor combined can range from $200 to $500 or more depending on parts availability and the technician's labor rate.
Can I fix E73 myself, or do I need a technician?
A knowledgeable DIYer can start by checking that all cable connections on the filter circuit board in the 3-zone module are secure and free of corrosion. However, if the fault persists after reseating connections, replacing the filter or generator circuit boards involves working inside a high-voltage appliance and is best handled by a qualified technician.
Is it safe to keep using the cooktop while E73 is displayed?
You should not continue using the 3-cook-zone induction module while E73 is active. The code signals that voltage output from the filter board is outside safe operating parameters, which could pose a risk to other internal components. Other zones on the cooktop not associated with this module may still function, but the faulty module should remain off until repaired.
