What E 76 / E 77 Means
E 76 is a communication error in the three-zone module for the center zone, and E 77 a broken heat sink temperature sensor for the center zone. For E 76 Electrolux checks the communication cables and replaces the filter board and center generator board; for E 77 it replaces the center generator board.
Common Causes of E 76 / E 77
- Communication cable to the center generator
- Center generator board heat sink sensor failed
🔧 One Safe Check You Can Try
Reset at the breaker and avoid the center zone until serviced.
⚠ Why You Shouldn't Go Further Than That
- Both involve boards inside the induction module.
- The cooktop must be lifted for access.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
