Wolf Cooktop Error Code E73

E73 indicates that the power module detected an open circuit at terminal E3 during its self-test routine. This means the module cannot sense a complete electrical path through the heating element or wiring connected to that terminal. The cause is typically a loose connector, a disconnected wire, or a failed heating element at the E3 position.

No. When E73 is active, the cooktop has detected a fault in the element circuit and has stopped normal operation as a safety measure. You should not attempt to bypass or ignore this error. Continued use with a wiring or element fault could pose a risk of further damage to the appliance or create an electrical hazard.

Repair costs vary depending on the root cause. If the fix is simply reseating a connector, a service call fee may be the primary expense, typically in the range of $100 to $200 depending on your location. If a heating element needs replacement, parts and labor combined can range from $200 to $500 or more. A power module replacement is generally the most expensive scenario, potentially ranging from $400 to $800 or higher including labor.

Some causes of E73, such as a loose or disconnected wiring connector, can be addressed by a knowledgeable DIYer comfortable working around appliance wiring. You would need to inspect and reseat connectors at the element and at the power module. However, if the element itself has failed or the power module needs replacement, those repairs involve higher-voltage components and are best handled by a qualified appliance technician.

A power reset may temporarily clear the display, but E73 is generated by the power module self-test that runs each time the unit powers up. If the underlying open circuit condition at terminal E3 is still present, the error will return on the next startup cycle. The fault must be physically corrected before the code will stay cleared.
