Error code77
ApplianceInduction Cooktop
Affected model seriesE36IC75FSS platform
Quick answer
Electrolux induction cooktop code 77 indicates heat-sink temperature sensor circuit is open for the center-zone module.
Model compatibility: Electrolux reuses codes across series and control generations, so 77 may mean something different on another appliance or platform. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Electrolux induction cooktop code 77 points to heat-sink temperature sensor circuit is open for the center-zone module. The display narrows the diagnostic path, but it does not prove which component should be replaced. Use the observed symptoms and the full model number to confirm the correct diagnostic path.
Read this display narrowly on the documented control platform: heat-sink temperature sensor circuit is open for the center-zone module. The same display can accompany a cooking zone may shut down, so the next step is to rule out temperature sensor circuit problem before moving deeper into poor internal connection.
This service-level code family is documented for the Electrolux ICON E36IC75FSS induction cooktop platform. Other Electrolux induction generations can use different displays or meanings.

Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
Turn the affected zone off and allow the cooktop to cool.
Remove cookware and make sure ventilation openings are not blocked.
Clean the area around the cooktop without introducing water into the controls.
After cooling, restore power and test briefly.
Important safety warning. Stop if the glass or cabinet becomes unusually hot, the code returns quickly, or ventilation cannot be restored.
